I would first suggeste to deal with problem of machine stability and/or crashing models. It would be also good to upgrade to latest BOINC version - 5.4.11 Credit is based on trickles uploaded. Some models were not running long enough to rech and upload upload as least one trickle...which is why you got zero credit for such cases. But the are obviously models that lasted long enough to reach some trickles, which you should have been credit for, I think... |

How forgiving would climate be to changing operating system mid-WU?
(Message 23135)
Posted 13 Jun 2006 by Honza
Post: Yes, thanks for the observations. I still think there is actually no need for 32-bit BOINC (core/manager/studio/view/whatever). As BOINC communicates via sharing memory/DLL and doesn\'t need much memory (10 MB will do) and it doesn\'t perform any calulation...why 64-bit? But it needs ability to report \"I\'m running on 64-bit capable CPU + OS). What we \"need\" is 64-bit BOINC applications... It is still beta so memory usage may change (hopefully) before gold version. I agree it will be more demanding than XP - perhaps twice as much as I\'m used to with every next egenration of OS from M$. Even nowadays, one can use 2GB for hard-core gaming (not mentioning graphics works, rendering etc. where it was commong even years ago). The trouble with M$ and 32-bit always was and still is: it can\'t use 4GB. So, where 2GB for Vista + latest high-end high-resolution with high-details game titles might not be enought to run smooth, 4GB is not an option as it can\'t be fully utilized with 32-bit Vista (or XP SP2). I\'ve been trought this so I know what I\'m talking about. To lower memory usage, I have disable (actually removed from installation) redundant services and applications like remote desktop, M$ Outlook Express and many more... A 64-bit version of Vista looks like a solution (and XP x64 did the job for me as well). Still the drivers availability is kind of precarious - for example for my HP BI 3000 DTN - a $1000 piece of hardware...not a $50 crap of looks-like printer. Hopefully, when Vista goes live, HP will make proper drives if they were unable to make them for XP x64. Anyway, for now, I don\'t see much benefit running Vista in a near future. |

(Message 23096)
Posted 10 Jun 2006 by Honza
Post: I had no trouble *running* BOINC on Win XP 64-bit nor Vista. But installing, resp. attaching to the projects may be different issue. On Linux, 64-bit version may try to download 64-bit app. Issue of 32-bit app and 64-bit OS is being discussed on BOINC dev. list. BOINC is not ready for 64-bit - at least in term of reporting 64-bit availability (both on OS and CPU level). But once you get it running, transfering to another Win OS should be trouble free - 64-bit runs on WoW emulation (without effeciency impact). There is no need for 64-bit BOINC core, but reporting 64-bit OS needs some handling, IMHO. |

Post: Hi Charles, Doing climate research is HW demanding and Sulphur cycle models are even a bit more demanding on HD space. To be more exact, up to 2.7GB are used just before model is completed (about 1GB archive of completed model). 1GB HD...must be very old piece. Is it a typo? Only OS like Win XP takes more space. Perhaps you ment 1GB free. I would consider upgrading your HD anyway. It is usefull to complete at least first phase (partial results get uploaded) but completing whole model is what CPDN researchers are looking for. No, so far there is no other than Suplhur models available. Soon, there will be Coupled models which are less HD space demaning (but even more CPU intensive). |

First two mentioned are public and for general use. The classic one - phpBB message board (called classic among old-timers since it served very well during CPDN classic pre-BOINC era) is a treasure of CPDN where many aspects of the project are discussed over the years of CPDN. Structure of phpBB message board is a bit different than BOINC Message boards vs. Questions board. I believe I\'m not the only one that can get confused by different names of boards; when you are not pefrect at English...better ask for clarification - and thanks for that. Yes, SETI boards rearrangement looks like a good choice - for SETI, where \"number crunching\" dominates over Science since the project has started. I think CPDN is a bit different - science topis make a considerable amount of discussion. Rearrangement can be considered by CPDN team. What Jack Lass suggest apply anyway and participants should post topic in appropriate place. |

Post: Still, if this is indeed a resource starvation problem like I think it is (\"There are no child processes to wait for\"), the client should have waited for resources to be free, not errored out. Right?Problem well described. At what priority is Outlook running? Lucky me - I never used Outlook on my system but found a lot of problems with it over office computers: eating-up all CPU resources as a common one. How long should the BOINC core (client) waited for child processes (CPDN aplication)? If 30 minutes is not enough, should it wait even more in every case (e.g. Windows shutdown/restart)? I definitely would not waited half an hour until Windows restart. There must be a timeout limit...which was propably exeeded due to Outlook resource demands. The other problem on Windows and single-CPU/core machine is that when one process (application) with high-priority demands all available CPU resources, there are no available resources to manage the problem. Solution might be: (i) put both applications demanding resources on equal priority so they can share resources, (ii) having more CPU unit (dual-core, dual-CPU machine) so that each CPU unit handle each CPU resource demanding application (beware of processes CPU affinity), (iii) solution on OS level. I would first check out Outlook priority, do some maintining of Outlook (compact database, degraf disk as such application tends to fragments large files which results in slower running) etc. What AV solution are you using? There can be a connection with e-mail client. |

Post: codycowboy, please, look again - it\'s 30 Nov 2006, not 2005. 1115 hours might be right, but BOINC tends to overestimates time-to-complete of jobs. It will take couple of weeks to complete a CPDN model. |

Post: Agree with Les - CPDN is quite demanding and sensitive to HW overall stability. On the other hand, CPDN can be VERY stable - on one my machines, I have 33 completed models in a row (including Sulphur cycle) [ with only 2 failed during early alpha/beta stage last summer, which is not surpricing]. |

Post: Is there some kind of time-out that happens between trickles, or what?There is a 2-weeks time-out to the active machine count/status. The policy on re-sending inactive model, I assume, depends on the current needs of the project (e.g. when Sulphur cycle models are needed, Slab model will not be re-send when they error-out or become inactive). |

Post: Perhaps a simple fix like: when newer trickle arrives, put to state from \"over\" to \"In Progress\" again. This may propitiate people\'s curiosity and make it more consistent with the actual situation of individual model progress. Lookin at my results page, server status ain\'t no right. |

Post: CPDN is kind of different as of \"state\". Server will accept further trickles and even final upload - even after WU is beyond deadline. If you are doing regular backups and - for example - experience a power failure with model crash, you can revert to backup and continue your model. This is to enable participant to finish the whole model. In that perspective, I think, it does make more sense. |

Using them on a forum would need to make a .png (or .gif) files from postscript (an easy task for me) and upload them on a server with link to the forum post(s). If you need help with it, you can provide me with a link to download or send them to me via e-amil (prefer zipped as this should shrink zipe of postscripped files significantly). |

Post: Hi there, I assume you have upgrade to the 5.2.12 version as you have previous slab model about 90%+ completed. BOINC might downlaoded another model due to your setting in preferences (global) to prevent running out of work. A simple idea might work - on a work tab, suspend sulphur cycle model a let the slab finish; disable new work before that to prevent another SC model download. After finishing slab model, resume SC model and let it continue... |

sulphur version 4.22 released
(Message 17612)
Posted 1 Dec 2005 by Honza
Post: SC 4.22 for Windows downloaded and started fine. Download is a bit smaller (couple MBs). Sulphur_se_4.22_windows_intelx86.zip does no longer contains 6.3MB globe.tga file. Does it mean that it is no londer needed (when older 4.19 models are finished of course) and you managed to use only globe.rgb for the excellent graphics? I would say so because former 4.19 used 60+52MB when graphics is on, 4.22 uses 59+only 22MB... There might be a slight speed improvement (now at 3.12 sec/TS vs. 3.21-3.33 or other 4 SC 4.19) but it\'s too soon to make conslusions. Good job! |

Post: Thanks, geophi. Just about the same as for Intel (so far). This leave the (im)balance of AMD vs. Intel on CPDN quite intacted. When comparing your numbers, I just found that BOINCView gives ill numbers when calculating Completion times [for CPDN]; your calculations are correct. We should rely on sec/TS (since the early days of CPDN) and figure days-to-complete from them. Even a 5% gain would be worth the effort. With over 10%, a proposition suggested by Chris may be even more interesting. It will be interesting to get some Linux numbers as well... |

Post: Great news, Tolu thank you. Yes, great news. It is a slab model - just got one \'cause didn\'t want to till weeked when my regular slab 4.13 finish. Memory usage is about the same. It is soon to judge speed improvment after 10 mins of running but BOINCView suggest 1.9 vs 1.7 sec/TS (20days 2 hours vs. 18 days 5 hours) on Pentium D. I\'m interested in some figures for AMD as topic of AMD performance on CPDN is of interest to many CPDNers. Executables are about the same size. hadsm3se_4.14_windows_intelx86.zip now includes also globe.rgb and globe.tga which makes the initial download 4MB smaller. Good timing since there are hundreds of new users (from SETI Classic). http://www.boincstats.com/stats/project_graph3.php?pr=cpdn&table=users |

Post: I have AMD 2000+ 512 RAM 166 running 4.45B Should i upgrade to 1024 RAM ? XP Prof Dutch; running 16 h/day Zonk, SC takes about 65MB memory (with no graphics output). If you had HT Intel of dual-core (AMD or Intel), it would be twice that much. System itself may consume about 100-150 MB and depends on what services are you running (both system\'s like themes, remote desktop and many others that may be considered as redundant for many users and/or 3rd party like SW firewalls, antivirs, messangers, P2P clients...) It also depends on what else you are doing on this machine - office machine? Game box? Audio/video station? Generally, 512MB should be enought for common use. Having 1GB would not make CPDN running faster but compputer may run smooter when more apps running together. |

Post: BOINC Server Upgrade Done -- RAC Calc Changed, originial message at phpBB forum - http://www.climateprediction.net/board/viewtopic.php?t=3197 quiting Carl OK, the BOINC server upgrade (software, not hardware!) seems to be done, the web pages are updated as well as the underlying BOINC software. The BOINC forums have improved quite a bit I think (although I\'m sure the phpboard fans will still stay here! Smile I think I have the final RAC credit algorithm for CPDN -- let me know what you think. Basically it\'s like the regular BOINC RAC -- I sort of weight a vector of trickles with the \"exponential decay\" calc (so a week old trickle is half-full-credit for expavg_credit) etc. It seems to get numbers more in line with other projects, and weights recent trickles higher so it\'s more sensible for CPDN. and you\'re not as penalized if you have a slower machine (since before I was taking \"average trickle date\" which is not so great). |

When will a 64-bit version Bionic be released?

Posted 25 Mar 2005 by Honza
Post: > <a href="http://www.techreport.com/reviews/2005q1/64-bits/index.x?pg=1">A recent article by the TechReport guys on 64 vs. 32bit and Intel vs. AMD</a> Thnaks for the link, geophi. It's quite a good reading. I found this part relevant for CPDN as it is using Fortran compiler: "The performance gains from having 16 GPRs available will vary depending on the complexity of your code. Compute-intensive applications with deeply nested loops, as in most Fortran codes, will experience higher levels of register pressure than simpler algorithms that follow a mostly linear execution path." |

Post: > > Do you have any source link to this..'cause i'm really interested to know more. > > Only did a quicky search, but google helps ;) Thanks for the links. Perhaps i wasn't clear in what i'm iterested in. I know both CPUs are compatible on SW level, that Itaniums showed itself as a dead end, what general 64-bits registers offer as it have been mentioned in many articles over and over. More interesting part are speculations that Intel with it's Netburst architecture wasn't quite ready for 64-bit extension so that AMD64 may gain more from 64-bit (e.g. doing better on 64-bit). In some cases - Intel Presshots with EM64T running in 64-bit may provide even worse performance than in 32-bit. In other words, i was interested in technology part or real sw performance rathen than in marketing talks, sw compatability and user's comfort. |

Post: > Tell me if I'm wrong. But 64bit windows only brings an advantage if you use more than 4GB of memory cause of 32bit can't address to memory up the 4BG frontier. So you may only see performance gains if you're running appilcations with huge memory needs so that the system has to permanently use paging files. You are right about benefit of larger amounts of memory (and swapfile etc.) to be allocated in Win 64-bit. But using 64-bit general registers can boost performance as well. See for example this article, which is quite informative and has some performance tests as well. http://www.pcstats.com/articleview.cfm?articleid=1665&page=1 Note that it is about AMD64, not Intel EM64T. I expect AMD64 to do better on 64-bit but time will tell... |

Post: There are already quite a bunch of people waiting for 64-bit. Win XP 64-bit is annouced to April...being available to market as i have been told by M$. Albeit, none info about commond 64-bit aplication like Photoshop etc... or the guy i have been talking to from Adobe knew nothing. As some popular HW like modern VGAs etc. already got beta version of their drivers, i'm expecting themn to be released soon after Win 64-bit hit the market. AMD64 is quite cheap, Intel CPUS with EM64T are not...but at least are compatible with Win 64-bit or Linux 64-bit...as i have recently tested. I got the feeling that only 64-bit apps are missing (when both CPUs and OS/Drivers are soon to be available): starting from commond apps like Photoshop, Acrobat, 3D rendering apps and...not on the last place, clients for BOINC. Apparently, you will hardly see any ETA on those and it may take a while as Les pointed out... EDIT: i think there already is/was 64-bit complilation BOINC platform.... |

CPDN grants more credit than Predictor
(Message 10831)
Posted 14 Mar 2005 by Honza
Post: > One of the main differences from cpdn to the other projects is that cpdn is currently the only one that doesn't send the same wu to more participants and compare their results. This means if your host claims an amount of credit for cpdn work, that amount is what is granted - which is not the case per definition at the other projects. That's far from accurate. CPDN does resent some WUs of re-check consistency among different platforms. What it doesn't, is the concept of claimed/granted credit. Credit is granted upon actual work being done, not some synthetic benchmarks and others not-much-sayings numbers. You finish whole model, you get 6805.26 credit. As simply as that; no horse-trading. > As far as I can tell from Andrews link, it would seems that on cpdn there is not even such a thing as claimed credit. Yes. Claimed credit would make no sense on CPDN project. > Well, in either case, cpdn is not very comparable with the others as it is very different in how it works. Nope, is more easy and clear than other projects as of god-damn credit. Every trickle you sent (10802 timesteps, 72x per model), you get about 94.5 credit. As simple as that, no trickies - just trickles. The different amount of credit per day is, IMO, basically generated by different CPDN performance on different CPUs, e.g. P4 vs. AMD (to thank or to blame Intel Fortran compliler). It is a known fact that Intel P4s with HT can do a much more that AMD(64). Generally, P4s are good for CPDN a SETI, AMD is doing quite good on Einstein. |

Running Climate on Dual boot machine

Post: > Thanx Honza. Too bad they havent made that possible...I wonder why, I guess > the datafiles have the same format and such...it shouldn't need to be a big > problem really to make that possible... It is not as easy as one may think. I'm not expert on this but there is a lot inside the code, including visualization, needs of different system libraries, different file handling etc. and, first of all - compiler. > Another thing...I saw that you have a couple of 3 Ghz machines, Prescott CPU:s I assüme..I have 3 Prescott machines running, and they get so damn hot. ABIT tool reports up to 70 degrees...do you have the same ? Or do you watercool your machines ? :-) Nope, not a single Presshot in my home :-) I have tested some Presshot based machines lately, including 3.8GHz model...but are too hot with high power consumption + plus extra demand for cooling (noisy). Slow cache, long pipeline, expensive DDR2 (i'm used to 2GB RAM) etc. No thanks, i will wait for dual core CPUs before farther upgrade. I've got couple of old good Nortwoods with air Arctic Cooling and couple of AMD64 (with same cooling). A Pentium-M Dothan in desktop version is best choice for cold and low power consumption. But there are people running both Northwoods and Presshots in their farms - naming astroWX just as one of them - with no problem as of cooling and with good performance on hyper-threading enabled (running two models at once). There were nice threads about self-building of computer on classic phpBB forum, which is still shut-down. A thread of building dual-Xeon by UK_Nick with in-depth technical details and lot of nice photos is also deep buried there. Let's hope classic forum comes back soon... |

It was not possible to spot this before it acctually happen or had been tested. It's up to CPDN team to update those things. I also believe there are importants things to do such as new models etc. It may be recognized as yet another reason for having phpBB forum again, where stickes/annoucements can be easily updated by moderators so that cpdn team can focus on more important issues. |

Bad for CPU to run 100%, 24/7 @ 62 degrees?
(Message 10041)
Posted 26 Feb 2005 by Honza
Post: Hi mo.v, there is a thermometer on CPU - actually it's insede. I remember having a external termometer on Pentium II, back then. There is also one that measure mainboard chipset (which may tend to get hot as well) and some modern VGA has this feature on their GPU (graphic processor). "Modern" VGA cards can take 50Watts and also get very hot (60+ C). The problem is that it may not be as accurate as i seems and not every chipset solution is supported by every application (e.g. Speedfan, MBM and others). So, one may need to checked several appication before he sses any numbers. Quality mainbaords has a CD with such applications...

Post: Thanks for the answer, i understand your point now. I'm at university for couple of years as well (even being only a student) and i think i know little bit how it works. I have also been several years among leadership group of international non-profit organization with about 2000+ members in Czech only. Despite of this, i still think that no answers at all is bad scenario - it doesn't take long to write a bit about progress or at least acknowledge that problem is recorded and is on the list-to-do. See Les Bayliss post - i really know how you feel. Tolu has been working hard on Alpha sulphur cycle project recently (and it seems to be moving again) so it's likely that he is now working on upload servers. I can't say for sure since i don't know and there is, again, no answer. I can use Stratcat statement here as well - it's a conjecture, based on my prior experiences.

Agree. Limitations of BOINC board with combination of rather static web-site is not a good one.

Hmm, BOINC forum is not a good helper on that - yet. At least Private messages on phpBB were good. I' pretty that CPDN team is aware of problems we are dealing with and i'm quite confident that they are working on them. A limited time is always agains us all. See ad (4) - i think classic forum would be a more effecient tools to help other participants and a bit lighten that stress that rest on cpdn team. > 6.

If we were on old board, e.g. phpBB based forum, i would: - redirect you post in appropriate thread were pc stability tests and problem running model resides - but we don;t have classic forum as of now. - edit your post (e.g. moved it in appropriate tread) but we don't have moderator opportunity there - sent you a PM (privete message) but we don't have this feature as yet. - you may have been found an answer quite easy by youself since: old forum is better structured and seach function works pretty well; but you are on BOINC forum not the "old" one. Sorry for not answering you post straigh away - i'm using it for [again] illustration limitation of both BOINC forum and not having classic forum. Is your compures overcloked? Please, try to look in Questions and Problems were this type of problem belows. I can image you picked up this thread since it is obvious that it is still alive and you will get your answer soon.

Post: I'm in total agreement with geophi on what he wrotes (lack of moderation at all, missing stickies/annocements making forum a mess and people asking tha same question again and again). I don't want to repeat myself - mainly when things are apparent. I spent considerable time today by looking at phpBB forum and even done some add-ons and widening of functionality on Czech BOINC phpBB forum. Rich phpBB forum functionally can be brought to even another level that since cann't compare with those of BOINC (in considerable timeline). Other finding that seems to be relevant - i havn't found a proof that phpBB forum in version 2.0.11 have been hacked. More relevant, and what i consider of most importance, is that phpBB forum is not only rich on functionality, but classic forum already has a HUGE amount of knowledge on CPDN project, problem solving strategies etc. This is similar to lost of all classic CPDN MODELS that we have been computing for months. I also feel that CPDN community (which i count myself to be member of since May 2003) and it's spirit had already been somehow damaged by ignoring already existing way to put our knowledge base of classic forum back. There is nobody that wants CPNDer to push to phpBB; but everybody should have an option to share what (in significant way) enabled CPDN for BOINC exist and became a viable project. |

Post: I'm sharing concern and missing of OUR classic forum as many contributors do; thanks mo and many others. This point of view is not shared since the car never crashed! It's safe in garage (being repared?), locked so noone can even see it. It's not someone else's car, it's a shared car - note that apps like CPView, CPFarmView, Wowmugs designs, manuals how to perform computer maintenance, doing backup and many more are authorship of CPDNers that decicated hundreds of hours doing those things, helping both CPDN project/team and other participants. This would have been (and i dare to assess should have been) available to all CPDN participants so that they can run CPDN with less troubles and have deeper understanding hence stick with CPDN. As of the questions below, upon my knowledge, answer would be Yes, it doesn't need any large space (even less for running CPDM model!), rather fast and reliable internet access, no need to top hardware neighter. Yes, it can be raised by the sale of WoW mugs (will there be eventually possibily of buying?) and donation (as has already been proposed for buying better compliler so that AMD users and 64-bit application - as was availabe decade ago for Cray - can run their models faster hence bring even more benefit to CPDN project). But they issue can be easily considered irrelevant since a generous offer to host phpBB forum together with moderation/administration and with no cost for CPDN has been already made. There is already server built and running, forum set-up, even domain name such as cpdnforum.info can be registred to illustrate this it would be CPDN off-site forum (no to harm Oxford reputation) - again with no cost for CPDN.

My estimation is that sulphur cycle models may be available to participants by the time your models have finished; there are still issues to deal with and test before releasing beta and public version. In a first stage (e.g. alpha-testing) it is better for the progress of testing that participant familiar with both BOINC and CPDN test those models in order to provide feedback and chase bugs. > Thank you for the information about incorporating these effects in the new > models.

It think it was not meant as lack of trust. Any phpBB forum administrator in priciple has access to e-mails of registered members...and a few people may dislike it if a classic-and-ever-best phpBB CPDN forum data with user's profiles would be used. Doing a phpBB forum backup is a two-click operation for forum administrator - i do so on regular basis on Czech BOINC forum (now about 3.000 messages, incorporating all BOINC projects). Restoring it may be another story - i haven't had to do so, yet (emoticon missing). As i understand, a lot of people would be happy having even read-only version of phpBB forum since there is a huge library of valuable information with an easy and user friendly access. Perhaps phpbb_db_backup.sql can be edited so users profile are excluded but valuable information remains...why starting another forum from fresh when thousand of messages with clear structure has already been made with great effort; both by CPDN team and participants. |

Post: Back again after a beatiful weekend i spent learning to play didgeridoo; another 3 BOINC models uploaded and yet another crash of alpha model. Thanks for kind offer, Beezlebub. Sylvia is right about e-mail addresses etc but personally, i would rather have phpBB back with may e-mail address on yet another place than be considerably limited by BOINC forum. There was a poll several months ago (on phpBB, of course) about phpBB vs. BOINC forum- 3/4 votes were for having phpBB. Personally, i see having both forums a wise choice - with preference of phpBB. With respect, i can't agree with Carl's arguments (e.g. a lot of new people etc, vocal of few 'regulars'.). Actually, i would interpret it as an argument for having phpBB back (with working a better searching functions) since, as geophi points out, there are the same qeustions again and again. Everyone should keep in mind that those 'few regulars' helped building an unique spirit of CPDN forum (and yet unmatching to other DC projects), helped deeper understanding of CPDN and enabled a real CPDN community to exist; i wouldn't be so involved nor had visited Oxford and travelled that far without it! A limited personal and time sources within CPDN team is another argument for having readable phpBB forum with some advanced editing features etc. phpBB was pretty effective of guiding new members, having stickies and annoucements to point of important issues (when CPDN web-site is quite static). I think that phpBB did very well during BOINC launch - a similar spike of new members like we have now. I agree that CPDN team is doing pretty well on releasing materials about CPDN etc... but as you can see, there are strong voices for phpBB resurection. As i see it, the list of missing features on BOINC forum only got bigger. There has been such discussion about missing feature back in Aug 2004 (now buried in phpBB forum, of perhaps on BOINC forum as well but can't find it) and a long, long list of them. To name and summarize some of them and are still considered as important, may be even more than before: - working search facility - greatly limited post editing and styling for non-HTML geeks (majority of participants); for those knowing HTML still more time consuming. - stickies, annoucements - moderators, administrators - who's on-line - mark-as-read - list unread posts on 1-page (instead of 9 different pages like now) - general users friendly interface - no preview of written message - PM (private messages), now substituted by 'Ping name' topics which is mostly ineffective for more that 20 people now in Alfa CPDN). Participant from forum is effectively unable to contact other participant via forum. - polls; they were pretty popular, right? - editing threads like split, re-arrange, lock, edit, delete - limited 2-level threads resulting in a mess-like post vs. 3-level hierarchy - sending subscriptions notification repeatedly (phpBB does it only once until thread is read again) ... And, for sure, lot more i can't think of right now. > If any of the admin people are reading this, I will offer phpBB on my hosting > site server for a cpdn forum so as to keep it off your servers so it doesn't > compromise your security.

There are a lot of other CPU types to run (AMD XP, AMD64 Winchester, mobile Pnetium etc.) and yes, some overclocked machines as well.

There is not reason for this on single processor machine. It is not possible and even if it would, it would actually slow-down processing.

Acutally, there is a small bug in computing credit that gets corrected upon every stats database update (several times a day) but RAC remains affected. > It does say it will take 35 days to run one model though, is this normal? Yes, it is normal. And it is a good measurement (together with sec/TS) for CPDN performance. It is a know fact that Intel P4s with HT on are doing considerable better than AMD. This may make you feel that your AMD64 is a bit slower comparing to other machines (e.g. P4 at 3 GHZ) but one needs to compage AMD64 vs AMD64 etc. > Any tips and recommendations would be appreciated, > Dale Your are welcome :-) Hope to help.. |

Running CPDN on a corporate network
(Message 8163)
Posted 30 Jan 2005 by Honza
Post: Hi Frenchy, it is a good idea to consider putting such resources to a useful project - where i consider CPDN being one of them. What apply to a small network that some of us running at home may in many aspects apply to a large scale as well so i'm about to share my experience... As for network traffic, there is about 8MB download of CPDN client for the first time; each other model download takes only 10kb. A trickle is a size of packet so there is no worry about overloading of internet connection at all. Final upload is about 7MB. On some [older] machines, a HD or RAM demand may be an issue: 64MB RAM /1GB HD space for each running model (on P4/HT multiply by 2 if 2CPU are enabled in BOINC preferences). A monitoring feature/utility of BOINC client over LAN (such as BoincView) might be very usefull. You can monitor BOINC clients' progress and send commands like "disable network access". CPDN usually runs with no need for baby-sittings; i got machines running for weeks on 24/7 basis with no need for intervention. Any farther questions welcomed. Hope to help. > Hello everyone, > My main concern at the moment is the number of times the PCs would need to > access the internet to trickle, I would not want to affect our Network traffic > at all and am wondering whether there would be a way of preventing the PCs > from trickling until the end of the process or only at a time when it is > convenient (during the night for example). > > Any experience in the corporate environment and/or suggestions about the > trickling bit above will be highly appreciated. |

The timing is perhaps bad but was not a matter of choice. Security issue is an important one and nor CPDN nor KMi nor OU should be careless about it. I still agree with Marj that it's a shame having all the valuable information deep burned in shadows. Another idea - would having a phpBB up in a read-only mode be considered as a security risk?

HadCM3 became operational towards the end of 1997, so projecting a normal rate of increase in computer power (doubling every 18 months) up until 2003/04 (the target timetable for operational delivery of HadGEM1) suggested that a model of approximately 15-20 times the cost of HadCM3 would be affordable at that time. This was factored into the design to allowing something like a 6-8 times cost increase from higher resolution, with a further 2-3 times from additional physical complexity. |

From an Einstein forum: The bug that is fixed concerns possible loss of work when starting the benchmark (which happens e.g. when you upgrade the client, but also about once a week). In principle it affects all projects, and every time the benchmark is ran gives a possibility for breaking the current project. It turned out that the CPDN app currently is the one most sensitive for this bug, and because of the very long time the CPDN WUs take, it also does the most damage to this project. But sooner or later every project may be affected. |

Post: Hi virex, Well, good idea but doesn't apply - we both are running all P4s with HT on and two models simultaneously (which does improove final performance). Let's date put another assumptions: - BOINC benchmark tests are CPU-numbers blind. e.g. having HT, dual of even multi-cpu machine doesn't run more benchamrks threads hence donesn't affect final score. Take a look at faster quad-Xeons with HT on. - Prescotts with larger but slower cache/memory access then Northwoods tends to do poor in such tests; AMD64 or FX can easily outperform all Intel CPUs because of their build-in memory controller. My final assumption is that Prescotts will do a bit slower than Northwoods in BOINC/CPND. They might benefit from larger cache in distributed.net effort or other apps where apps itself fits in cache. > i'm assuming that Jim has hyperthreading turned on, and you don't.....that would explain the benchmarks |

Post: Hi Mo, i'm sure that is it that critical. - 2 weeks period is considered as machine active status for statistics. It is known that under classic, one might download model, complete it whole off-ilne (no trickles) and then upload. - once model is finished, it will stay on Transfer; i'm not aware that it will fade-away after some peorid - one can upload model until it's deadline - which is propably fare more then December 2004. Well, a bit of speculation i must admit (haven't been profeed} but still what common sense might suggests... HTH > Hi everybody. I know about the server problem, but noticed what Steve said, > that if he can not 'update' (do you mean trickle, Steve?) within 2 weeks of > the last time, his whole model will be lost. > > What does this mean?

Post: Hi there, as for uploading results, you might get lucky sending them to climateapps2.oucs.ox.ac.uk/cpdnboinc instead of regular www.climateprediction.net (the same apply for attaching to the project etc.). First, i would backup whole BOINC folder. You may want to try editing account_climateprediction.net.xml and replace second line where is located. Be warned - this is only desperate idea which hasn't been tested. > I have finished my dataset (100%) and I have been trying desperately over my past few days to upload to BOINC. I get the following error: > "Cannot resolve hostname: www.climateprediction.net (valid name, no data > record of requested type)." > What to do?

Hi geophi and thanks for redirection to appropriate thread - still can't get into using BOINC forum... I also undertaken some rearch... it seems that phpBB SQL exploit is active. http://www.phpbb.com/phpBB/viewtopic.php?t=239819 Solution/remedy is there http://www.phpbb.com/phpBB/viewtopic.php?t=240513 http://www.phpbb.com/phpBB/viewtopic.php?t=240636 http://www.phpbb.com/phpBB/viewtopic.php?t=244451 An SQL exploit can maybe overload CPU/System so there is no spare CPU cycles to provide webpages data at www.climateprediction.net hence causing whole www.climateprediction.net unaccesable. That's perhaps why marj was able to load a bit of CPDN web but was 'thrown out' soon after. EDIT: No announcement that the site was going to be worked on today as far as i can say. But CPDN has of version 2.0.10 today; i got the feeling that upgraded recently from 2.0.8 ? |

Post: Hi there, today i experienced [another] exit code -5. I think this one is a bit different in term of conditions. I opended large file in Photophop and made some operations where Photoshop had taken over 1GB RAM - I have 1.2GB available to Win, rest 800MB are dedicated to RAM DISK (exclueded memory). This situation must have become stressfull for both Photoshop and BOINC (2 concurrent modells under P4 HT). When i realized that Photoshop needs more memory than i expected, i immediately shutted down Maxthon and BOINC. One model died (with premature upload upon BOINC restart), another went fine (and still going). I relalized that i don\'t have swap file (but plenty of memory, heh - still not good for M$ Win). My report also suggest a question: how is BOINC dealing with low-memory? Can some exit code -5 be triggered by Win on low memory? |

Agree that life with classic forum is much easier - i still miss many feature: 'view post since your last visit' to mention one of most crucial. I already checked CPView with BOINC completed model and it work just fine. I also noted about 0.5C diffrence in above surface temperature comparing to web-graph; perhaps a slight shift on y axis? I still hope and pray that Carl will make time to make this shared DLL - it would enable to monitor model progress (CPFarmView monitoring both classic and BOINC!) and other things. One that cames to my mind was already mentioned - some mechanism that will know that models goes wrong to upload and new model download would be suggested to user.

Post: Hi Kobel, sorry for your troubles... You can try a 'Reset project' which should download new files and perhaps fix the problem. If not, i suggest to Detach from the project which should release your WUs so you can be propably able to delete mentioned host(s) |

Post: Actually, classic CPDN phpBB forum is usually highly evaulated - as opposite to SETI forum. I think there are two major reasons: participants and forum itself. Participant: you can find a bunch of pretty educated folks on climate/enviroment topics around the board. Forum: i [and i'm not the only one] found phpBB forum very user friendly - unlike BOINC [albeit i like idea of scoring post]. There is also interconnection between participants and forum using administrators, moderators, stickes, annoucements and many many others - as you can find in 'Future of the forum' thread [link already provied]. BOINC FAQ link can be found right on BOINC Question and Problems. Since i don't consider my English good enough to make summaries, i would suggest you to join effort of making FAQs etc. - crandles has done excellent job so far on this and he would appreciate your helps i guess...

Post: Hi Zydor, what you have described sounds like a good idea [and it's has already been started]. I would like to add some comments from my experience suggestin other possible ways... Core team is usually quite busy and even working during weekends - Carl is a good example of this. Some are very computer skilled, some are skiller in climate prediction stuff - still their knowledge is limited by number of computers and possible configuration. My point is - you can never experience whole variety of possible problems and their solution. I think that moderators and experienced users can help there also - see links for an example of already made efforts: http://www.climateprediction.net/board/viewtopic.php?t=2299 http://www.climateprediction.net/board/viewtopic.php?t=2227 There are some infos already provided by CPDN team - Getting started. http://climateapps2.oucs.ox.ac.uk/cpdnboinc/download_main.php I would think that this is a good point to start reading - but a lot of people don't read it! If they did, we haven't had any 'CPDN WUs too large' since it clearly says that CPDN model takes weeks to complete... Unofficial BOINC FAQ is also usefull http://homepage.mac.com/pauldbuck/site-boinc/faq/faq-over.html There is always good suggestion "Read before ask" and majority of people do follow. And it almost certanly happens that new issues arise - like 'Visual Fortran run-time error'. A collective investigation of participants and core team should follow to help fix the bug. This is also a good way to make live easier for participants - make BOINC and it's project more stable with less aby-sitting needed. For sure, there are still many issues that needs some improvments - including BOINC forum board is guess... http://www.climateprediction.net/board/viewtopic.php?t=2194 |

Post: Hi Millen, not a stupit guestion IMHO. I would suggest to backup classic (it's about 8MB .zip file in my case) and then uninstall. It enables you to run again (perhaps you like THC slowdown experiment which will not be available for BOINC) need with no need to install again and re-register. Note that BOINC and classic can run paralel - which makes sence on P4 with HT. But you would propably decise to run 2 BOINC models... Also, archive folder can be moved to a CD of DVD for futher analysis (IDL, CPView or perhaps specially ad-hoc utilities provided later by CPDN team to test some hypotesis). |

Post: > Why Honza's transfer appears to be working, I couldn't say. Unless maybe the trickles are approached differently? With the other BOINC projects, you aren't credited until completion.

Note that is has been done under Beta - not sure about public version... > However, as me and UK_Nick just found when finishing a model, BOINC is still trying to do something with credits at the end, because we received double credits. The credits we had from the trickles, and the credits BOINC gave for completing the WU. (when the other projects normally receive them) Should be fixed now... > So perhaps a surprise is in store for Honza as his model completes? Could be interesting to see what happens.

Making a full BOINC backup prior to following instruction is recommended; actually, i'm doing regular daily BOINC backup as when beta testing classic client. Note that filenames/folder naming is a bit different in Beta but structure remains. [pasted from old Alpha web page before it is flushed, text by Carl]. If you are currently running a client with the old client/website that is fine, it should finish and upload. If you running the Windows or Linux client and would like to 'migrate' your current alpha test run to use this improved client and website, please do the following: Note the currently running experiment/workunit name in your "old alpha" BOINC, (i.e. "4000_0043120000") You are going to want to copy the files matching this workunit name that are in your old_boinc/climateapps2.oucs.ox.ac.uk_cpdn/ folder, i.e. it would be the 4000_0043120000.xml file and the 4000_0043120000 folder as an example Download the 'special' BOINC 3.90 client, attach to this site: http://climateapps2.oucs.ox.ac.uk/boinc with your old authenticator code (you can get your code emailed to you from the Your Account link You should get a new download of the CPDN client (3.15) and a new new experiment (or two...or 100 ;-). If not please check your user preferences and make sure that you have enough disk space, and that your BOINC setting allows for using a disk drive that has a high enough percentage, etc. Note the name of the experiment that starts up (i.e. "4110_004324334") Stop your boinc client Copy over your "old boinc" experiment .xml file and the folder with the same name. Rename the new experiment .xml and folder to something else (or you can delete it as it will not be needed) Rename your "old boinc" experiment .xml file and folder that you copied over to the new experiment name from boinc (i.e. rename 4000_0043120000.xml to 4110_004324334.xml and 4000_0043120000 folder to 4110_004324334 in my example) Restart your new boinc client, it should pick up where you left off in the new model. One odd quirk is that now we are using the BOINC CPU time accounting (as we should) which will show time reset to 0 (and consequently the finish time will be a little odd as well <img src="http://boinc.mundayweb.com/cpdn/stats.php?userID=56&trans=off"> |

Post: Thanks for link, Mikey. Chapter 4 discuss the resolution issue. Is it possible to have hybrid resolution: double resolution of ocean (192x146) and normal resolution for atmosphere? Chapter 4 also suggest the horizontal resolution can be adjusted to one needs and computer resources, but vertical resolution (layers) should be chosen more carefully. A compromise needs to be found - larger resolution will also affect dl/ul traffic etc. As i understand from Open Day, we run rather more models with larger parameter space and less amount of detailed models (like Earth Simulator?). |

Note that another 2 WUs 'exited' AFTER migration when 2 CPUs used (P4 HT). It might have been with connection of prolonged heat (30+C over a week with no rain at all) and other consequences. I have checked CPU temp again and it's 63C; not so bad should be better i guess...others P4 are up to 60C. @ Ian, after rereading Andrew's updated post there (http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=206) i tend more to ascribe the 'exit code -5' problem to extreme heat in the room where affected conputer was. But unusual thing is that it was during dark night which confuses me. Will check CPU fan etc... Thanks for mentioning other external causes - now i see that you are pretty familiar with issue. I remember some note on Open Date about result of idenatical model on different machines (e.g. re-check) but can't remember exact match in % (was it 95% ?). Somebody will hopefully fill-in the gap or perhaps Open-Day archive will help there. I'm quite sure it was 100% match. |

I agree with you that client doesn't have to be adjusted to overclockers needs but to be stable as it is on 'factory settings' and not the other way round. Let's calm down and have a look again: note that this machine is VERY stable (regardless slight overclocking i havent found ANY problem so far; stability tests incluede) and completed some amount of standard and THC slowdown models. My question (still not answered) was also about migration of on-going model - together with 'exit code -5'... Also note that i'm not the only one with 'exit code -5' so connecting it apriory with decent overclocking is a not precedent. Statisticaly: how do you explain model going toward Phase 3 and then crashed and some models crashes after couple of hours just in beginning? Climate: some model crash due to paramteters Beta: note that this is still beta - client and new BOINC 4.0x as well. I'm not sure if you have been there during Alpha stage or had opportunity to talk to CPDN team in face... i can asure you that their are doing very good job. Also note that compiling 500k+ source code such as climate model is very sensitive (unlike SETI etc.) and that were many problems due to different compilers and switches - not only for Win. Well, it also seems that AMD CPUs tends to loose on Intel P4 (unlike under classic CPDN as 1+year experience shows) due to compilers and it's switches. AMD with some switches tended to be faster and, yes - unstable...There must be decent balance of optimalization for performance and stability. My point is that there are many factors that impact (in)stability... What would you say if i report another crash under 'factory settings'? What woud you say if there are more and more people reporting this problem? This (and other 3 boxes i'm running at home) have showed a good proof of stability and compatability during more than a year running 24/7 classic CPDN since its early beta. |

Post: From the behaviour and performance it looks like a real Dual CPU machine :-) I'm getting 26 ts/min with on 3.2GHz P4 or AMD64 3000+ I think it's because sec/ts calculated from CPU time and timesteps of each model. I got about 1.8 sec/ts during alpha testing and i guess that if i haven't reseted the project and continue running old and new one, the behaviour would be the same... I would also expect both your models decreasing it's speed, resp. figured going down. |

Post: Hi Yeti, there is no way (so far) to use multiple CPUs on a single model -> each CPU is simulating different model. You can get some +15% on P4 HT but keep in mind that it need another 50-60MB of RAM, HD space etc. You may also find interesting running single BOINC model and keep your 'classic' CPDN/Win running another; assuming you are on Win platform. |
