1) Message boards : Number crunching : Some food for thought. (Message 37879) Posted 31 Mar 2010 by Minicluster Post: http://boincstats.com/stats/project_graph.php?pr=milkyway quotes us at about 1.61 PetaFlops. Now, I am taking this number with a very very large grain of salt, but still ... 1 petaflop is damn impressive. With some sloppy conversions, we are looking at about a quarter million cpu years. If that doesn't cause you to pause, read it again and think about that. anyway ... Carry on.
2) Message boards : MilkyWay@home Science : Milkyway@Home Science status? (Message 37737) Posted 25 Mar 2010 by Minicluster Post: Thanks for getting back to us. Looking forward to the writeup.
3) Message boards : Number crunching : Why is 5970 classified as 5800 series in BOINC? (Message 37674) Posted 23 Mar 2010 by Minicluster Post: Don't tell anybody, it's a secret. Gosh.

5) Message boards : Number crunching : Win7 64 Bit Catalyst 10.1 Bluescreening.... (Message 36330) Posted 8 Feb 2010 by Minicluster Post: After installing 10.1, boinc was crashing due to memory access violation. Logs showed it was CAL related. Rolled back and everything was good. (Had a similar problem with GPU-Z which seems fixed as well). 4850,275,windows 7 64-bit.
6) Message boards : Number crunching : NVIDIA GPU Bug? (Message 35686) Posted 15 Jan 2010 by Minicluster Post: Hi there, Take a look at http://developer.download.nvidia.com/compute/cuda/2_3/toolkit/docs/NVIDIA_CUDA_Programming_Guide_2.3.pdf. Page 109 out of 145. You want Compute Capability >= 1.3. The document shows you picked up cards with 1.1. For ATI cards, refer to: http://developer.amd.com/gpu/ATIStreamSDK/ATIStreamSDKv1.4Beta/pages/ATIStreamSystemRequirements.aspx (superscript-1 Does not support double precision floating point operations) 58xx series should all support Double Precision. Thanks. (Could we create a sticky about what cards are supported or put that information on the front page?)
7) Message boards : Number crunching : Testing ATI Application Availability (Message 35451) Posted 11 Jan 2010 by Minicluster Post: Oh I know, I would like to use 3 GPU's without taking out a CPU task. My system crunches only Milkway. Cheers to future stability.
8) Message boards : Number crunching : Testing ATI Application Availability (Message 35447) Posted 11 Jan 2010 by Minicluster Post: A quick question, why does the app report that it uses 41% of the CPU? If it not too much trouble, may you look into perhaps lowering the number? perhaps closer to the magic number of 27% ? Thanks again.
9) Message boards : Number crunching : Server down twice today?? (Message 35441) Posted 11 Jan 2010 by Minicluster Post: All 8 5970 GPU's and 2 4850 GPU's crunching flat out here. :-) That's a crazy amount of flops right there.
10) Message boards : Number crunching : Testing ATI Application Availability (Message 35317) Posted 11 Jan 2010 by Minicluster Post: Well, it is slowly picking up ATI and CPU work units, and it will be nice when it grabs a few for the green goblin. Thank you for promptly fixing the problem.
11) Message boards : Number crunching : Testing ATI Application Availability (Message 35286) Posted 10 Jan 2010 by Minicluster Post: I would suggest you stick with the optimized app until they sort out the problems with the scheduler.
12) Message boards : Number crunching : Testing ATI Application Availability (Message 35260) Posted 9 Jan 2010 by Minicluster Post: I think the project scheduler thinks the ATI app for NVIDIA. Explains why I can get work (I have a gtx) and others can't. It is also corroborated by the fact that boinc requires an NVIDIA card to do the crunching (on the ATI app).
13) Message boards : Number crunching : Testing ATI Application Availability (Message 35247) Posted 9 Jan 2010 by Minicluster Post: I detached and reattached my machine, but still no automatc WU download. It seems the server sees only the Nvidia cards. Did you check your profile to make sure the project is allowed to send ATI work? I was hoping to get cuda work, so far it hasn't. May someone take a look at the project scheduler to see if it is confused?
14) Message boards : Number crunching : Testing ATI Application Availability (Message 35237) Posted 9 Jan 2010 by Minicluster Post: Finally got a work unit (had to detach and attach). Seems the system is a bit confused? My 4850 seems to have been eaten by the green goblin. Also, 1.99 CPUs? Really? Windows 7 64bit, boinc 6.10.18.

16) Message boards : Number crunching : Project Throughput (Message 34757) Posted 22 Dec 2009 by Minicluster Post: Anyone dare to venture a guess on the throughput of this project? Do there exist server side scripts that can give an (approximate) amount?
17) Message boards : Number crunching : 2.8 p4 running 50% crunching 1 wu-why? (Message 34726) Posted 20 Dec 2009 by Minicluster Post: Windows Taskmanager: (percentage reported) * (number of cpu's reported) = actual percentage. So each task is actually maxing out whatever processor it was running on when it was sampled. If something is reporting >50% then that means that either Windows's scheduler is over counting or the process is multithreaded and using all available processing power. As for pausing a project. The boinc client scheduler has builtin checking that will more or less give you the exact same result without the need of babysitting the work units. If it believes that it cannot make deadlines, it will reorganize the tasks so that those with earlier deadlines will run first. After all is handled the scheduler will try to bring the projects back in balance with the set resource share.
18) Message boards : Number crunching : Credit lowering (Message 30648) Posted 13 Sep 2009 by Minicluster Post: Credit history comparisons can really only be compared between similar types of work units. Multiple trendlines can be created (cropped between credit/application/workunit changes) which shows progress clearer than examining or comparing histories of two users or projects. Are cobblestones flawed? Maybe, but anything else that is substituted in will be just as flawed when you compare projects. FLOP comparison will never work. There does not exist a universal currency between projects. Perhaps we should setup a credit exchange program?
19) Message boards : Number crunching : Catalyst 9.9 released (Message 30632) Posted 13 Sep 2009 by Minicluster Post: 9.9 is working great so far. Vista64 4850 && 3850. Hopefully it fixes the slight VPU-reset issues I have been having with 8.12.
