Post: most any computer that\'s fast enough to run CPDN is going to support at least SSE or if its Intel based will most certainly support SSE2. im not shure exactly when AMD\'s started supporting SSE2 but id think anything fast enough for CPDN would have this. |

Post: I know credits are only recalculated once a day so no credits for 2 days seem a little odd. Must be a problem somewhere. |

Post: Hmm well i only have 1Gb RAM of Dual channel corsair 675Mhz ram on an Intel 965 chipset (Intel motherboard) with onboard video. it shows up as close to 1Gb in Ksysguard so i don\'t think the Vid card is poaching too much RAM. |

Post: Actually i have 3 Wu\'s for some odd reason on my C2D. One hasn\'t even started yet and when the 2 run together they really slow down on the sec/ts. I wish i could convince CPDN to use just one core and leave the other core for other boinc tasks without resorting to modified clients. for now i just live with it but it would be nice if i could just leave CPDN run full time on one core. P.S I know i haven\'t trickled for a while but the Wu\'s are suspended for AA5 and ill return to a 50% work share after that. So thats not an issue. |

Post: That should work if they just take a combined total and use that :) Expect to hear more complaints though from the top team in certain projects as the fall back spots (if they do).. I think one project is the best idea myself as everything is still ongoing. |

Post: On the Linux box try installing BOINC 5.8.1 it does wonders for your benchmarks On my C2D it up things considerably. It almost benchmarks as good as a windoze machine. |

Post: You can set BOINC to only run when the computer is not in use. This can be found under general preferences. Personally though i leave BOINC running 24/7 because it scales back seamlessly when i need to use the computer. Im yet to endure BOINC related slowdown as it just cuts back to 0 when you demand the most out of your processor. |

Post: im finding this annoying, its gonna take me 40 hours atm to do 1 year (or 1 feed back,) 5.65 s/ts Yes this is certainly not a project for short Wu\'s. There are probably many projects better suited to you if you like your Wu\'s short. Beware that 1hr 20mins is a short Seti WU my slower rigs often run over 10hrs on a seti long WU so it might not be as short as you expect. A good project if you want to have a set time limit for Wu\'s is rosetta@home. In your Rosetta preferences you can set your own Wu length. the machine you have quoted is just marginal to run a CPDN WU if you check the min specs they ask for. Also out of interest why 10gb virtual memory? Thats an absolute waste of hard disk space. If your using swap your going to slow down massively as is. If your using much over a gig of swap you might as well not have RAM your going to be that slow. generally its not recommended to tell windoze what to do with swap file size. It almost manages it competently on its own. If your on Linux you only really need a swap twice the size of your RAM and even then you are unlikely to use any at all. If you wish to look into another project try the Team BOINC@AUSTRALIA Website there is a list of active projects down the left hand side of the page with an explanation of what they are trying to do. Also im unsure if im reading this right but we dont install BOINC on other peoples (even friends) machines without their permission. It could be considered theft. But then again i may have just misunderstood and i hope i have. |

Post: Sadly this is a true Dual Core (C2D) If apps run side by side i go from 1.9123 sec/ts to 2.1045 sec/ts which is a significant increase (but mainly of the second WU not the first). Also by the 9th trickle my first WU has increased to 1.9715 sec/ts. Im worried how slow this is gonna get by the end. Maybe i need more RAM but i thought 1Gb would be enough for a Linux Machine |

Post: LOL i cant even get the graphics to display. Oh well im saving a few cycles for the app anyway. I found my t/s times in the trickles section. Although alarmingly its much longer when running 2 models side by side and slightly longer with every trickle. |

Post: The current CPDN workunits are rather large lol. Even my Core 2 Duo looks like it will take around 1900-2k hours to finish a WU. But its got a 50% share so i guess i should finish it fairly easily. Another thing to think on is the fact there is only one size WU available so i don\'t suggest CPDN for older machines. I wouldn\'t try this on my 2Ghz Celery for example (supposedly its fast enough but i doubt it). But maybe a late p4, core 2 or AMD dual core i would. Whats sort of machine is this on? Also estimated time is just that an estimate it could be wildly wrong. CPDN Wu was listed as 2850hrs on my Core 2 Duo E6400 yet so far im processing at least 1/3 faster than the estimate, so wait and see if the estimate is accurate. |

Post: Im very new to this CPDN thing but i have a query. My results page shows i have 259.2 (or something like that credits, but when i look i have 2 trickles recorded. Any idea why i don\'t have credit for both of them or is there some sort of delay/lag in the result being credited. Im just a bit curious |

Post: I just joined up today and run all Linux machines except for one my little sister uses (it doesn\'t crunch all that much either as its not full time on like my other machines). I did post a how to on setting up a Kubuntu Linux boinc cruncher in the seti forums. Im still waiting to hear back if it worked or not for people new to Linux. One thing i have found is that if you install it this way you can setup your projects and then reboot your machine. As its starts before you log in it crunches away as if it were CLI only (low to no overhead) yet has a nice GUI for easy setup. I haven\'t gone into how to strip back the Install but its a fairly small install anyways. My smallest hard disk is 3.2Gb and has it installed on it with over 1.5Gb (1.7Gb if i remember correctly) to spare and a 500Mb swap drive so it can be stripped back fairly heavily if someone is comfortable doing this. Anyways heres the link if anyone wants to give Kubuntu a try http://setiathome.berkeley.edu/forum_thread.php?id=36333&nowrap=true#486018 Add to the end of this how to - reboot your computer and do not log back in. |
