1) Message boards : News : CPU applications deployed and CUDA memory requirements changed (Message 486) Posted 26 May 2011 by [SETI.USA]Tank_Master Post: With the new nvidia memory requirnment, does http://moowrap.net/forum_thread.php?id=16 need updating? I updated http://boinc.berkeley.edu/wiki/GPU_computing#Attach_to_projects_with_GPU_applications pointing to it so users can get the most curent info.
2) Questions and Answers : Windows : 1.01 experence with mixed GPU card types (Message 191) Posted 10 May 2011 by [SETI.USA]Tank_Master Post: Purpose of this thread is to provide feedback for system running both ATI and nvidia cards in the same computer. I havenâ€™t had major issues thus far with running MOO on my system with the latest app. (computer ID 32) I have an ATI 6970, a NVIDIA 430 and a NVIDIA 295 all in the same comp. With the recent app, the ATI card is sitting at 99% GPU load, however the nvidia cards are at 50-53% load across all 3 nvidia GPUs with a core setting of -1. With a core setting of 1-, I get around 80% load across all 3 nvidia GPUs. The nvidia app still takes a LOT longer to complete than the ATI app. In general, it takes around 15-16 min for an ATI app to complete on the ATI card and about an hour and a half to complete on the 3 combined nvidia GPUs. In my experience, the ATI setting of .9 CPU is rather high, as it general uses 0-1% of my i7 (8thread) CPU, so that could be lowered. The CPU load for the nvidia app on my system as around 8-10% most of the time. Completed nvidia tasks so far: http://moowrap.net/result.php?resultid=73191 (core = 10, 1h 10m) http://moowrap.net/result.php?resultid=73180 (core = -1, 1h 40 min)
3) Questions and Answers : Windows : Long run times (Message 189) Posted 9 May 2011 by [SETI.USA]Tank_Master Post: so far i havent noticed any issues with a single ATI 6970 and windows 7x64 with the latest ATI driver.
4) Questions and Answers : Windows : Multi-GPU task takes longer than single-gpu task (Message 81) Posted 4 May 2011 by [SETI.USA]Tank_Master Post: I am getting the same thing on my nvidia cards. I have a GeForce 295 (dual GPU) and a GeForce 430 in the same machine. Currently, only one of the 295 GPUs is 50% active and the other 2 are completly idle. I to have complete a few WUs on my nvidia card. The single ATI 6970 card in the same computer is working as one would expect. Might I sugest running one WU on each GPU core instead of one WU for all GPUs? This may minimise issues for systems with a mix of varing card types as well.
