Credits accruing but no trickles sent????
(Message 41364)
Posted 27 Dec 2010 by skgiven Post: I noticed a few trickle update pending messages a few days ago and then finished tasks stopped uploading. The cause is a crashed upload server (power outage). Things tend to behave strangely when they are not working properly. I checked my pending credit and it suggests quite a lot of work to add to the tally, http://climateapps2.oucs.ox.ac.uk/cpdnboinc/pending.php Result ID Workunit ID Host ID Claimed credit 8182465 6249578 794294 226.80 8182772 6249640 794294 151.20 8338165 6274938 798383 2,570.40 9231729 6488047 981208 1,995.84 9422923 6528706 981208 2,081.77 9422975 6531095 981208 2,081.77 9422976 6532521 981208 2,081.77 9490809 6575330 981208 2,081.77 9516615 6587782 981208 2,081.77 9991674 6568525 981208 2,081.77 9992330 6551093 981208 2,081.77 10815674 6781676 981208 2,081.77 10815686 6781682 981208 2,081.77 10847538 6746957 981208 83.16 10896103 6429409 981208 2,081.77 11734809 6898261 1117464 6,176.41 11734833 6898265 1117464 5,280.84 11734840 6898267 1117464 6,176.41 11800772 6911453 1117464 6,176.41 11893960 6928697 981208 7,145.52 11893976 6928699 981208 5,656.87 12420807 7292459 1117464 617.72 12421592 7262840 1117464 988.30 12422027 7293668 1117464 1,019.18 12422951 7294582 1117464 1,358.88 Pending credit: 66,441.64 No doubt the techs will sort out their upload server and the database when they get back from their holidays. |

Performance on hadcm3igeo "coupled" models
(Message 41363)
Posted 27 Dec 2010 by skgiven Post: From the list of apps/models/experiments on offer (below), is there a definitive (or even rough) answer as to which tasks get the most credit (run the fastest/do the most) on which systems? UK Met Office HadSM3 Slab Model UK Met Office HadCM3 Coupled Model Experiment UK Met Office HadAM3 UK Met Office HadSM3 Mid-Holocene UK Met Office HadAM3P UK Met Office FAMOUS UK Met Office HadAM3P European Region UK Met Office HadAM3P Southern Africa UK Met Office HadAM3P Pacific North West For example, which task would run the fastest on an Phenom CPU, which on a IC2Duo and which on an i7? Also, which operating system is the fastest (while being stable)? XP x64, XP x86, Vista/W7 (x64/x86), Linux (x64/x86). The reason I ask is that I would like to configure my i7 system for maximum throughput (optimization) if possible. I would be happy to install the fastest operating system and run the fastest tasks for my CPU. Thanks, |

Running Boinc GPU client w/ CPDN
(Message 37624)
Posted 3 Aug 2009 by skgiven Post: Folding @ Home also runs CUDA programs using NVIDIA Cards, and a similar program using ATI cards. http://folding.stanford.edu/English/DownloadWinOther Note you will need to have the drivers installed first! For NVIDIA Cards, make sure you have an up to date driver and Cuda program installed. I have not used an ATI card, but it works just as well. Again, the other programs are GPUGRID, Aqua, and the pointless SETI. The Milkyway also do an ATI project and may one day finally even manage to get an NVidia effort up and running. Presently just begining the Alpha. |

(Message 31440)
Posted 21 Nov 2007 by skgiven Post: I was just asking for help in contributing to the project. I thought this was a help forum. \"The answer is the same as for the previous poster\". Does this mean that you cant be bothered thinking about it or telling me the answer? \"leave BOINC to get on with it and it will\". Get on with not doing what I want it too in the same way it has been doing. Why would I want to do that? \"it takes time for BOINC to work things out each time\". What? It\'s a computer program! Thats what it does. If thats your effort at help I\'ll work it out myself.

Posted 20 Nov 2007 by skgiven Post: I have the opposite problem to this user: I want climate predictor to run all the time on 1 core of my quad systems, but it does not run at all! This is because the other projects are cheating with the time settings - I sence an interproject quabble here. CPDN sets the deadline to about a year in the future, while the other projects I am connected to set theirs to a few days (often 2 or 3 days). As a result they are always in the \"Running High Priority\" Status, and CPDN does not get a look in as the next one goes straight to that status and these projects keep picking up more work. Malariacontrol seems to be the worst offender, but Tanpaku, Boincsimap and World Community Grid also do this. HOW Can I Adapt the Settings so that CPDN actually runs once and a while??? Thank you, Whenever Climate Predictor start to run, it prevent ANY other projects from running. It always run as \"High priority\". It completely ignore any resources sharing preferences. |

How do I set BOINC to use both CPU cores for climate prediction?

Posted 11 Feb 2007 by skgiven Post: It\'s not possible to run one model on both processors. [/quote] How then can I use both cores when I run Rosetta, Tanpaku or similar project calculations? |

How do I set BOINC to use both CPU cores for climate prediction?
(Message 26728)
Posted 11 Feb 2007 by skgiven Post: I want to use both CPU cores for climate prediction on my Pentium 945 (dual core). It only uses 50% of CPU power at present, and will take 93 days to run a project, at 24h per day. I will probably upgrade the system between now and then. So if I cant set this up to work flat out there is no point starting, I will just do one of the other projects like rosetta (all my other systems use 100% CPU, and all are dual core). I dont know whats up with this project? Any suggestions on how to get the CPU use to 100% of both CPU cores? |

Posted 5 Jun 2006 by skgiven Post: I am participating in the BBC Climate change experiment, running BOINC Manager 5.4.9. The estimated time it will take to do one set of calculations on my fastest machine is nearly 3 months, and about 5 on my slowest machine. Wise up and break the calculations down into realistic sizes, so that more people will actually finish the calculations. 3 to 4 months is a ridiculous time to spend on a single calculation. I guess that half to about 80% of people would be put off by this and not even start (or drop out quickly). The chances are that about 10% of people will have a serious software problem in that time and have to reinstall, losing all data. Probably the same proportion of people will change their machine, and many will just give up on it. All in, I would guess that you are excluding 85% of would be participants. I would suggest performing a calculation that takes about a week on a standard computer would do. Are you getting any data on the effects of running processors at 100% for extended periods? How many processors fail (indirectly because of fan failures, or just burn out)? What effect does the extra heat have on the Mean Times To Failure for the other components? How much is spent cooling the office? Is the process actually contributing more to global warming, than slowing or stopping it? Big questions for a big project! Worth discussing I hope. GL |
