21) Message boards : Number crunching : Milky Way -- no credits in Linux? (Message 58270) Posted 15 May 2013 by mmstick Post: > million credits in 3 weeks Got my Ubuntu 13.04 with a Radeon HD 7950 generating 1,000,000 credits every 3 days. Just attached to this project yesterday. Doesn't BOINC automatically download the latest version of a project's software by itself? All you need is the latest version of BOINC. I don't remember having to manually install software for any project I'm attached to.
22) Message boards : Number crunching : Why so restrivtive small stock of tasks for me ??? (Message 58258) Posted 14 May 2013 by mmstick Post: Then again, I suppose 7770 proprietary drivers have DP processing speed cut by 1/4th, so a 7770 would take 4 minutes per task instead of 1. The moral of the story is don't use low end hardware on Milkyway.
23) Message boards : Number crunching : computation error on HD 6970 - drive 13.4 (Message 58257) Posted 14 May 2013 by mmstick Post: I am leaving the dual Xeon on x32 XP for the time I keep it running. When W2K ran out years ago, I had it protected by ESET's full suit and it ran faultlessly, and protected, until I recently upgraded it to XP pro. No problem when the security patches stop coming in from my W2K experience. Why not use Linux? You'll get much faster processing speeds on Linux over that bloated, outdated, badly compiled OS. Catalyst 13.4 on Linux works perfectly fine with this project.
24) Message boards : Number crunching : Why so restrivtive small stock of tasks for me ??? (Message 58256) Posted 14 May 2013 by mmstick Post: That's not specially for you, we all get max. 40 tasks per GPU, for high-end ATI cards that's a bit more than half an hour of work. So with 15 hours you have a quite large cache ;-). If you don't want your GPU to idle in case the project has some issues with servers, you should configure a backup project for it (0 resource share). My high end 'AMD' card, Radeon HD 7950, completes 40 tasks in ~13 minutes. 20 seconds per task. A low end AMD card, HD 7770, completes 40 tasks in just ~40 minutes. Therefore, you are REALLY off on how fast AMD cards are.
25) Message boards : Number crunching : Request help updating app_info.xml for Linux (Message 58255) Posted 14 May 2013 by mmstick Post: I'm having similar issues. I can't get app_config.xml to work on Linux. BOINC manager says it detects app_config.xml but it is ignoring all the parameters. Update: Found solution <app_config> <app> <name>milkyway</name> <max_concurrent>4</max_concurrent> <gpu_versions> <gpu_usage>.25</gpu_usage> <cpu_usage>.25</cpu_usage> </gpu_versions> </app> </app_config>
26) Message boards : Number crunching : GPU Requirements (Message 54701) Posted 7 Jun 2012 by mmstick Post: You might want to mention that most of the NVidia GeForce cards are poor for double precision tasks, especially the Fermi cards. Tesla's: Tesla C2050 (515 gigaflops of double precision performance) 3GB The Tesla C2050 costs something like EUR 2.000+ (not sure how much that in US Doller is) and in comparison to the latest ATI/AMD cards has relatively poor DP performance. For example: AMD 6950 costs something like EUR 200 and delivers 563 Gflops in DP! source: http://www.legitreviews.com/article/1488/1/ No wonder that the top 20 computers all use AMD/ATI GPUs. Wow thanks for that 2 year old review. LMAO! NVIDIA is the best! And it is actually true. However, Kepler is even worse than Fermi at DP and SP tasks. At this rate everyone should just settle for some HD 79x0 cards with 4000 GFLOPS SP and 1000 GFLOPS DP for the lower 7950, add 30% to that for HD 7970, and double that for HD 7990 on a PCIE3.0 slot.
27) Message boards : Number crunching : 7850/7870 (Message 54699) Posted 7 Jun 2012 by mmstick Post: My HD 7950 takes 41 seconds per task without an app_info.xml. Can't find a sample app_info.xml though, would love to stop the droops in utilization between completed and starting tasks.
28) Message boards : Number crunching : AMD 7970 GFLOPS question (Message 53867) Posted 31 Mar 2012 by mmstick Post: 3.79 Tflops = 3790 Gflops. But any decently overclocked 7970 will get well beyond that, even my 7950 reaches up to 4 Teraflops single point precision-wise.
29) Message boards : Number crunching : AMD 7970 GFLOPS question (Message 53855) Posted 30 Mar 2012 by mmstick Post: I'm running a Radeon HD 7950 (Using Catalyst 12.3), complete a unit and the task reported: Estimated AMD GPU GFLOP/s: 3942 SP GFLOP/s, 986 DP FLOP/s with a core frequency of 1100Mhz, It can run at 1200Mhz after fiddling with Afterburner but I'm a bit lazy at the moment.
