1) Message boards : Number crunching : Multiple GPUs on same WU (Message 7630) Posted 21 Apr 2017 by Engagex BOINC-SETI Post: My rig already had 3 Nvidia cards, so I thought I'd try my hand at adding an AMD card (HD 7470). I run a server build and Lubuntu dektop. Needless to say I was SOL and just replaced the AMD card with a fourth Nvidia card. I have 3 more cards on the way and I'll have a total of 7 GPUs. Here is my client output: http://bit.ly/2oRiRBc They are all happily crunching along. My previous comment about scheduling seems to be debunked except for when a (multi GPU) Moo! Wrapper task is pending, it won't DL any new GPU tasks until the Moo! Wrapper task has ran. So Mikey, are you saying even though it says it's using 3 or 4 Nvidia GPUs for one task it's actually not? Here is the first completed 4 GPU Moo Wrapper WU: http://moowrap.net/result.php?resultid=54926647
2) Message boards : Number crunching : Multiple GPUs on same WU (Message 7607) Posted 28 Mar 2017 by Engagex BOINC-SETI Post: Yesterday (3/27/17) at 4:30 pm MST, I had this task that was ready to go: http://bit.ly/2mMFJT2 When I got in this morning (3/28/17) at 8:00 AM MST, it still hadn't ran. I have my tasks set up to run for 60 minutes at a time. I had to suspend all the running GPU tasks simultaneously for it to run. It finished in 00:28:34. Is there a priority scheduling problem with multiple GPUs on the same WU? Seems like it would be the same as a Cosmology or other (4CPU or 6CPU task) Please let me know any info you have. Or if I should post this on the general Boinc forum. Thanks, -Doug P.S. How many Nvidia GPUs will be utilized simultaneously by a task like this? I can have up to 7 cards on my MOBO. Would 3 AMD cards work as well? Could Nvidia and AMD be used on the same task?
