    Chaps

    Since the hooha about uploading files to the server I have had nothing to work on for the past 2-3 days.

    climateprediction.net Message from server: Project has no tasks available

    1) Is this happening to everyone else?
    2) Anyone know when more models will be available for download?

    Cheers

      I too have had no work for a while ...

      But the servers are all showing 'no problem' ...

      Help?

        As the server status page shows, there are no tasks available. Well, actually there have been some today but they have been snapped up by whichever machines put in the request in the short window before they are all gone again. I am afraid those of us who don't have the luck to be sending the request at the right time will have to wait till a fresh batch of tasks is released.

          Lately -- the last few months anyhow -- when the project releases new work (aside from retries) it's been in big batches of several tens of thousand at a time. When that may happen again -- who knows -- but it probably will happen fairly soon.
          Meantime I accept work from other projects that have real short turnaround.
          CPDN is the one project I focus my computing resources on whenever work is available.

            This project doesn't always have work.

            When one of the four groups of researchers decide what they want to do next, they contact the project people, and give them the information that's needed to create a new batch of work units.

            However, the Southern Africa group, based in South Africa, haven't been running models for a while, so they may have finished. Or not. :)

            So, everyone just has to wait until more work is available. And then there'll be 35,000 plus computers after it.

              Andrew

              Your computer has crashed every work unit sent to it.
              Perhaps you should use this lull to find out why.

                  Interesting, there seem to be a fair number of tasks being released, I have just got one. - I had expected to be down to using one core but now one core has a pnw while the other is slowly making it's way through a full ocean model.

                    In fact, 4 tasks downloaded including an saf, though this is probably a re-issue.
                    The number of tasks in progress seems to be going up or at least not changing very much which implies other tasks are going out and anyone who is patient will grab one/some of these tasks if they are patient.

                      I got a new SAF WU for one of my machines the same way. The problem appears to be that the demand is greater than the supply. When a small number of WU’s are dumped into the hopper (mainly reissues) the thousands of machines calling for new work snap them up immediately.

                        And I guess the ration will get worse till a new batch is issued.

                          You can tell if a model is an original or a reissue by the name.
                          On an original, the last number is a zero.

                              Hi, Desti,
                              Me, too. However, we must keep in mind that the different science teams require time to evaluate results (would we have it any other way?) before releasing the next set. These chopped-up tasks are a far different management problem than when we ran entire models; of course, as you know, they required months at 24/7 and some peoples' whining/whinging resulted in the operation we have today -- including its large up- and down-loads.

                              We must also remember that our two support staff were thrown into the deep end of a very complex years-old project and have not yet developed miraculous instantaneous turnaround skills.

                              And, should we mention all the firefighting required by the wondrous server system? That, too, will require time and money to rectify. Meanwhile, brute force ...

                              I'm reminded me of an old saw, from decades ago: The difficult we do right away; the impossible takes a bit longer.

                                  At least I grabbed some of the spare WU's to feed my processors.

                                    Looks like there is a batch of pnw tasks released - they keep appearing in small numbers on the server status page and number of tasks in progress has gone up by about 3K

                                      Looks like a few thousand PNW - just been growing and growing - probably re-issues. But anyhow plenty work for now

                                                One PNW failed after a few seconds on a newly-rebuilt machine. All three in the Work Unit failed in, apparently, the same way. (Can't check because the server fails requests to look at any of the failures in the Work Unit.)

                                                Probably not a machine failure (I hope!) because three PNW ran together (with a WCG task) and completed okay. (47.03 / 47.08 / 47.09 hours, running concurrently on stock i5-3550.)

                                                  I haven't received any new WU since June 5th, so I'm now out of work on 2 hosts.

                                                    Actually thats an ATI request. The project doesn't provide work for ATI or Nvidia. However there are only the occasional resends for CPU work requests at the moment until the scientists create more work units. There were some pnw's created about a week ago but they disappeared pretty quick (I managed to get some on 2 machines, but the rest missed out).

                                                    If you are running BOINC 7.0.25 or later there is a way to prevent it requesting ATI and/or Nvidia work (on a per-project basis) which it will never get and then backing off for an hour before it can ask again. If the BOINC server software was more up to date the project could do it as well, but they run a pretty old version. If you'd like to know how just ask.

                                                      For the last few weeks the only WU available have been re-issues of WU that failed earlier. I've got a few of them.
                                                      Some were WU that hit broken machines on the first pass - these are working ok on my machines.
                                                      Some were misconfigured at the get-go and fail again.

                                                      When the backlog of these types of WU clears -- thanks to all you contributors --

                                                      Hoping there's funding for more :)

                                                            I'm in no hurry since Summer is here, and it's a hot one. Once Fall starts, I will look forward to having a few thousand WU to crunch. :)

                                                            Edit: That said, running Linux means I don't get any of the EU models... so waiting is required in my case.

                                                                      The i5 laptop had three tasks, of four running, that decided to go into 'high priority' mode. When this happened no more tasks were requested by BM 6.2.12, despite the '10 days work' setting. After the fourth task completed, three tasks were left running, BM subsequently requested work and downloaded one task. Now that it has four tasks, three high priority and one normal priority, BM is still not requesting any more work despite the setting for '10 days' work.

                                                                      During nearly 8 BOINC years solely on cpdn, although sight of 'high priority' is rare, I have never seen BM with this behaviour before. I presume this is BM doing as it wishes? Just curious if anyone has seen this behaviour, if is a BM version issue in 6.2.12, or a common BM behaviour?

Of course, I know that there are very few CPDN tasks available just now. But, like hagar, it is the absence of requests in the event log which seems surprises me. At present, I have 4 tasks running, one of these due to finish in 16 hours, none waiting to start, no other BM apps running and my preferences set for a maximum work buffer of 9.9 days. But no requests for new work. Curious.

                                                                          • The "Computer is connected to the Internet about every" setting is now the refresh level. If you have it set to 0 BOINC won't fetch work for a project until it is starved of work.
                                                                          • The sum of that and the "Maintain enough work for an additional" setting is now the maximum work buffer size for the project.


                                                                          I've no idea what's preventing hagar's 6.2.12 from requesting work, but enabling work fetch debug might give some clues.

Is this the same in the 7.0.28? If so,what setting should it be set at to have it begin requesting work at the 240 hour (10 day) mark?

                                                                              I don't know the wording of these new versions, but would have thought that they'd be different to reflect the new usage.

                                                                              If it's still the old text, then try:
                                                                              "Maintain enough work for an additional" to 9
                                                                              and
                                                                              "Computer is connected to the Internet about every" to 1

                                                                              That should give you 10 days of work, then no more until your work level/load drops down to 1 day to go.

                                                                                      That's a nuisance. The workunit your model came from must be normal because another computer has managed to complete a model from it. Server status looks normal at the moment but if we have more reports of the same download problem we'll have to tell Jonathan.

                                                                                      You're unlikely to get another Hadcm model as very few are available at the moment. I expect you'll get a Hadam EUR model instead.

Trouble is there were so many computers requesting work by then that you had to be lucky in the timing of the request for new work to get one. What is needed I think is a large batch of the full resolution ocean models as they take long enough to complete that even the fast computers don't exactly romp through them!

                                                                                                    I hope this time-out doesnt take to much time, and when CPDN will restart we got some new numeric models with 64 Bit and Multi-Core-Support.

Weeks of unforseen disreachability (PSU dead, HDD full, Databank inconstistant, Hacker-Forces) are really not cool.

I assume some of those papers influence the IPCC report even if they don't appear as part of it.

I am writing this on my laptop running on batteries and posting from an open wifi network that I happened to be able to jump on because I nave not had any electrical power since hurricane Sandy hit the East Coast of the United States last Monday. The Authorities are saying that not all electrical power will be restored until Nov. 11.

                                                                                                        All the food in my refrigerator has spoiled, I am going blind from trying to read by candle light (how did they do that in the old days) and I have no heat because the furnace doesn’t work without electricity (it was 37 degrees F last night). This is getting real old, real fast.

                                                                                                        So no new work from CP, WU’s don’t download fully, full servers that make it difficult upload results, no problem!

                                                                                                            I'd suggest a lot of candles, large ones if possible. A bit late though if you don't already have lots on hand.

                                                                                                            On this mornings news, (local time), one station showed queues of cars 20 blocks long, with the driver of one having been there for 7 hours.
                                                                                                            There were people with containers getting petrol because their cars didn't haven't enough to reach a station. And one man was arrested for pulling out a gun to try and push into the queue.

                                                                                                            It's nasty out there, Jim. Stay inside as long as you can.
                                                                                                            Good luck with the aftermath.

                                                                                                                    Guess that I am lucky, about 25 miles north of where the distruction started, only had one gutter dented from a tree and the new car is covered with dents from flying branches. Neighbor has a 75 foot tall Maple tree that is dying and it lost a lot of weak branches. Dents can be repaired, gutter put back up all that is important is that no one was hurt here.

                                                                                                                    The neighbor has wanted to take that tree down for a long time but it is hard to get at, so would cost almost $2,000 which he can not afford. I refuse to park the car in my parking space in back of the house when a storm comes because of the tree. This time I parked in the front yard and the still got the car. Left the old car in back (the one I wanted the tree to crush) and it was untuched. Just can't win with that tree.

I suspect it had something to do with the time change of time on the night of daylight savings switching since thats the night when it happened. Anyway, I lost my jobs and haven't been able to get any new tasks for CPDN since that time and wonder if there will be any forthcoming soon.

It's a big job so I don't think they'll do it until next week. I'd be surprised if they release any new batches of workunits before the upgrade, so be prepared to wait for say a week. Crunch another project in the meantime.

And the most likely cause of this is if the clock backup battery was flat/faulty.
                                                                                                                          If there's no backup battery, when the computer was last turned off or rebooted, the time would have reverted to some time/date in the far past. So when the daylight saving switch happened, the time/date may have leapt forward a looooong way. BOINC doesn't like this, and must have decided that all of your work was now obsolete and deleted it.

I am still without power (and heat) 12 days after Hurricane Sandy and there has been a second storm called a Nor’easter that was almost as bad. It dumped as much as a foot of snow in some places. We still don’t know when we will get our power back.

                                                                                                                                    There is something to be said for having hurricanes in August. At least it is warm afterward. I should go before my battery dies.

Hope the power is back soon. Longest I have ever been without power over here is a couple of days. And if that happens now, I have a woodstove that will heat one room and the hot water, with some gain for the rest of the house. I can understand why a friend in rural Scotland who gets rather more frequent and longer outages than Cambridge has his solar system set up so he has several hours of battery at night if the mains goes off. OUr Solar is grid linked and stops working if the power goes out. Not that it has for more than half an hour since we had it installed a year ago.

I am writing this on my laptop running on batteries and posting from an open wifi network that I happened to be able to jump on because I nave not had any electrical power since hurricane Sandy hit the East Coast of the United States last Monday. The Authorities are saying that not all electrical power will be restored until Nov. 11.

                                                                                                                                            All the food in my refrigerator has spoiled, I am going blind from trying to read by candle light (how did they do that in the old days) and I have no heat because the furnace doesn’t work without electricity (it was 37 degrees F last night). This is getting real old, real fast.

                                                                                                                                            So no new work from CP, WU’s don’t download fully, full servers that make it difficult upload results, no problem!

                                                                                                                                            While it's obviously dreadful what has happened on the eastern seaboard, and you have my sympathy, we still appear to be awaiting an explanation as to why the project has in effect been moribund for some weeks now. Or is the reason hidden somewhere else in a different thread on one of the two message boards? (Why do we need two message boards?)

                                                                                                                                              The project people have been fixing a series of problems before releasing more work. And this is likely to continue for a while yet.

                                                                                                                                              No details are likely to be made available.

                                                                                                                                              This board is the standard BOINC message board. The other board is the original one from before BOINC was released. It was originally hosted for many years at the Open University in Milton Keynes.

                                                                                                                                              It's handy to have two for when the server with the other board is down, so that messages can still still be posted.

                                                                                                                                                I'm getting frustrated. I haven't gotten any WUs for a while now. The last dozen or more that I did get either crashed or hung on download so I can understand being dropped to the back of the line.
                                                                                                                                                But since then I have changed from a 2 CPU board to a 4 CPU board with faster CPUs and really want to see if this will make processing these weather projects faster. But without any work to do I can't find out. Before with only 2 CPUs I would have to suspend processing on the Weather project in order to process my other BOINC projects and still have a CPU to do my work on. Now with 4 CPUs I can dedicate one to processing weather data, 2 for other BOINC projects as well as a third project that can operate on my GRU board and still have one for my own work. But I need to have something to process and with no WUs to work on I will never find out if my new configuration is of use to the weather project or not. So right now I am processing 3 BOINC projects on my CPUs, one on my GRU and a 5th project on my 4th CPU when I am not using it to do my own work yet have no weather WUs to process to see if they will work and if so how fast they can process weather WUs. My previous 2 CPU computer configuration had trouble getting the work done quickly enough. Though I have processed 133,000 units of work for the weather applications it has been stuck there for several months now. Meanwhile my SETI credits have gone from 135,000 units of work when I changed my configuration to over 227,000 in just a couple of months. While it is nice to contribute to SETI, it would be better to contribute more to the weather applications since they have more immediate impact upon how we live on this earth right now just as my contributions to World Community Grid have soared with my new configuration to over 88,750 which is primarily concentrated on Childhood Cancer studies.
                                                                                                                                                Is there something I can do to get back into the good graces of the Weather projects after the dozen or more straight failures I suffered with my previous configuration? If so, what?

Other projects benefit, in my case it is malariacontrol.net, although this projects does not give as many credits and does not run so hassle free than climateprediction.net.

                                                                                                                                                    As for your new computer, the few models that made it through to your computer have also failed. (Apart from one that was aborted.)
                                                                                                                                                    This is a problem with your computer, as it is with your other computers.
                                                                                                                                                    You'll have to look in the stderr list on the page for each model to find the error message. (Click on the + symbol to expand the list.)

                                                                                                                                                    As for "back of the line", there's just under 36,000 computers after work, and only around 5,000 to 10,000 WUs released at a time, so good luck with getting any when they do start to show up again.

Is this correct or has something gone wrong? Screenshot below

                                                                                                                                                        And they're very touchy about being interrupted. It's possible that there's several reasons for this. Some of us don't turn off the computer or interrupt them in any other way until they finish. :(

I do have my computer on 24/7 but am also running several other projects like Seti which I started in 1999 (only because I thought the moon would be leaving its orbit from earth)

                                                                                                                                                                System is an AMD 8 core 3.1ghz, so I'll just let it do its thing and try not to make it angry at me by interrupting it too much.

If that happens for a HadCM3N task when running restart dumps at 25%/50%/75%/100% ...

With a bit of lot, not too long after that.

This week? Next week? Before the Sun turns into a red giant and swallows that Earth?

Now there are just under 17,000 computers. Still a bit more than the number of models usually released in the big batches.

                                                                                                                                                                        My guess is that it'll be OK by Christmas. Just as there was a saying in 1914 in the UK, that the war in Europe would be over by Christmas. And they were right; it was over by Christmas, 1918.

I presume that means some tasks have been released, even if they do go too quickly to see them as available.

My computers run 24/7 and allow new tasks is set. Nothing is suspended so I don’t see why I don’t catch at least one of those new/old tasks.

                                                                                                                                                                                Ahhh. I think that the problem is that there are more computers than models. But I could be wrong.

                                                                                                                                                                                Has any one heard of a word spelt patience?
                                                                                                                                                                                Or ultra-marathon running? That should give one something to do while one waits for work.

                                                                                                                                                                                  With the limited number of cpdn tasks I had decided that the 4 cores would be back-filled with LHC Sixtrack science tasks. So today I turn on the revived laptop - there was just enough time to attach to LHC before boinc picked up another CM3 task from cpdn to fill the fourth core. It's now got a full complement of four CM3s fighting in boinc for air-time from 16 Sixtrack tasks.

                                                                                                                                                                                  I can only surmise that the virtue of 'Patience' was mis-heard by the laptop, XP and boinc manager. They applied 'Pertinaceous' instead.

I could let my dual core atom try for some cm3 tasks but given the time it takes to complete regional models I suspect I am better off leaving things as they are! The I3 machine has with the times it is switched off taken into account still got a couple of days to go before it is out of CPDN work. If it runs out it will get attached to WCG like the atom.

                                                                                                                                                                                    The atom does like it's new SSD hard disk though.

When some regional tasks come along, my atom netbook will be back in action for CPDN. In the meantime it is taking the best part of 24 hours for each task it runs. It now has a screenful ofWCG tasks to get rid of.

                                                                                                                                                                                        And it occurs to me that it's not possible to be attached to this project 24/7 as with other projects.

So computers after work and not getting any, are only connected about 23 minutes each day.

Still plenty of WCG crunching to keep it happy.

And now after waiting for so long I had new work for my Win7 laptop and it crashed too.

This can cause them to crash. Also it is recommended that you suspend the models and use the file > exit dialogue before shutting down. Also suspend the models if you are going to do any processor intensive work with the computer. Some have even suggested it is best not to run this type of model except on computers that are running 24/7. Unless you are able to carry out some or all of these measures the rapit models are going to be very prone to crashes. Also exclude your BOINC data directory from any antivirus scans

It's supposed to start with that, so the reply must have been corrupt or (more likely) empty.

Now I am getting 3 or 4 at a time and they are processing faster than they did with my old 2 CPU configuration. Also more of them are completing without ABENDS despite the instability of Windows 8 which ABENDS 4 or 5 times a day lately, probably because of too old device drivers. I thought going to WIN 8 was going to make my system more stable, boy was I ever wrong!
                                                                                                                                                                                                                I've gone from a bit over 122,000 in credits to now having over 242,000 in credits in just a couple of months so it looks like I'm finally making progress even though I am processing tasks in SETI, LHC, Rosetta, World Community Grid processing a half dozen different sub-projects, Cosmology, Einstein, Milkyway and Lattice Project in addition to Climate Predict. They each are sending dozens of WU's at a time to process (except LHC which still doesn't send a lot of work and still I have been able to process as many credits in the past 2-3 months as I had been able to in previous SEVEN YEARS I have been processing CP projects. The processing speed of my 4 CPU configuration is really amazing despite the unreliable nature of WIN 8 that has been so shaky that I have had to cease processing anything for days at a time instead of 24/7 as previously.

Despite a lot of effort by that machine, it has finished only three out of 31 tasks. There must be something seriously wrong if the success rate is only 10%.

                                                                                                                                                                                                                  If the machine is crashing four or five times a day then it really isn't going to do well with tasks of CPDN's size and duration. It would be a very good idea to find out what the problem is and to resolve it. Quite apart from any concerns about distributed computing, no machine should crash that often: the machine itself looks very capable.

I'd be very surprised if the instability is due solely or even mainly to Win 8 which was made for desktops and laptops just as much as for mobile devices.

In many cases I've also looked at the pages for the workunits to see how other computers managed with the same models.

                                                                                                                                                                                                                    http://climateapps2.oerc.ox.ac.uk/cpdnboinc/results.php?hostid=1261663

We can get plenty info from looking at the Hadcm Task pages.

This is almost always due to the the model itself producing impossible climate conditions, so that's the fault of the models, not your computer.

                                                                                                                                                                                                                    * However, quite a few models with exit code 22 did not crash with impossible climate. I think the problem in these cases is probably instability of the computer.

Jorden explains this error in his FAQs. This seems to point to a memory or RAM problem. Your computer has lots of RAM. Test it. Windows 7 has its own memory-testing/diagnostics program and I expect Win 8 has too.

                                                                                                                                                                                                                    If it fails the test using all RAM modules together, rerun the test with each of the modules in turn. If you find a faulty module, download MEMTEST and use that to double-check.

                                                                                                                                                                                                                    Are all the RAM modules the same type? A previous computer of mine ran beautifully with type A and beautifully with type B. But A + B produced crashes.

Never did work out what was different about the computer that let them play together - playing with memory bus speed didn't seem to make any difference in fact the one that let them play was a duron processor that still let them play with a substantial overclock.

And now after waiting for so long I had new work for my Win7 laptop and it crashed too.

If they all crashed simultaneously that usually implies something environmental (such as a power cut or windows shutting down before Boinc has exited). If it was a laptop, perhaps it tried to hibernate the tasks.

                                                                                                                                                                                                                                  I have found that the tasks usually survive an accidental trip through hibernation. Last week there was a power cut during the middle of the night. Both of my laptops went into hibernation when their batteries were exhausted. (Batteries only last about 2 hours when the machines is being flogged as hard as Boinc does.) Automatic shutdown is set for 20% charge. When the machines were restarted all the models had survived.

                                                                                                                                                                                                                                  I know that using hibernation is not a good idea with Boinc, but, it is a lot better than just having the computer run until the battery is dead and then crash. That’s just about a guaranteed model killer.

                                                                                                                                                                                                                                    There have been a lot of posts here about the fact that the project often has no work available. If you look at the “Server Status” page you will see that it reads “0” except for a few Hadam3’s that are almost certainly “zombies” that will fail in the download phase.

                                                                                                                                                                                                                                    Despite the fact that technically the project has no work, I have picked up 3 hadcm3n WU’s in the last few days. These WU’s are all reissues of WU’s that failed on other machines. They all end in _3 or _4. They have been around the block a couple of times already.

                                                                                                                                                                                                                                    In order to get these it is necessary that Boinc be running (duh). If you don’t have any work from CPDN run something. Run 24/7 (with an internet connection) if you can. The reissues are generated in very small numbers as they timeout and they are snapped up just as fast. The more you run the better the change. Running 24/7 the chances of catching one is greatly increased.

                                                                                                                                                                                                                                      * increase the work buffer to 10 days (though you have to make sure you don't get too much work from too many projects).

                                                                                                                                                                                                                                      * if you see that tasks are available and you're really keen to grab some you can temporarily suspend tasks from OTHER projects

                                                                                                                                                                                                                                      * if for any reason you suspend work from a project, BOINC prevents that project from fetching new tasks

                                                                                                                                                                                                                                      * if you can't get hold of new CPDN tasks, do consider joining other projects as well. Find them in the Tools menu of BOINC Manager. The projects listed there are all considered safe and reputable by the people in charge of BOINC at the Uni of California at Berkeley

                                                                                                                                                                                                                                      * check in the climateprediction.net preferences of your account that you've enabled all the model types you want. At the moment the model types are Hadcm3m, which is longish, and all regions of Hadam3p (Europe, Pacific North West, South Africa and we hope some Australia & NZ). If you want anything available just enable them all

                                                                                                                                                                                                                                      * if you're running BOINC tasks on a laptop make sure you're not letting it overheat by simultaneously running too many tasks for the machine's fans to cope with. Check temps by downloading (for example) Core Temp and also, if you're running GPU tasks for another project, GPU Temp. If you don't like the look of the temperatures, members here will advise you about what to do

We cannot change this setting which was decided to limit the load on the server. The countdown to the next hourly attempt is shown in the Projects tab of BOINC Manager. Do not try to ask for work now by clicking the Update button as this will reset the time to 60 minutes. Patience rules!

                                                                                                                                                                                                                                                  I'm running BOINC Manager 7.2.38. I do not see the countdown information you reference in the Project Tab...The fields are: Project, Account, Team, Work Done, Average Work Done, Resource Share, and Status (which is blank). Where is the countdown time displayed?
