OK. We have go with optimized apps! (Ignore those twenty five errors. I had to go set my file permissions a little looser) I'll be keeping an eye for invalids but currently I have cuda and CPU working and crunching. I'm actually getting some APs for the CPU as well, that's refreshing. ******************** Richard Haselgrove: (I'm running a nightly pre-release of 7.0.45 right now) Max CPU % absolutely is throttling the GPU as well. Example, Throttling Boinc to 90% results in the apps running at 100% and temporarily cutting down to 66% for short periods, to equal 90% time. During the periods when my CPU drops to 66% the video card is following suit as I can watch the temp instantly drop dramatically (over 10 degrees C), and then go back up when the CPU is back to 100%. So I am pretty positive that what you mentioned is working at least to some extent. My opinion, this stinks! I cannot throttle my CPU separate from my GPU. My solution for now is just leave 1 core free on the CPU and leave it at 100% time. This keeps things from bogging down my system. While still allowing my GPU 100% use. I'd rather have my cpu at all cores, throttled to 90%, but I can not do that now without throttling my GPU. :-( I guess I'll just have to keep following along with the pre-release versions or alphas until I get one that has the implemented separate control for GPU :-) **************************************** To everyone who helped me figure it out, and answered my stupid questions just so I could understand everything fully; THANK YOU! The moral of the story, a cheap Nvidia card can do MBs faster than a thread of my xeon processor, probably faster than several threads. I'll get details about that :-) (EDIT: initial results show the video card is doing at least the work of 2 cores (4 threads) on my Xeon) In the meantime, it's getting kinda crunchy and warm 'round here. I'm trying to get to my first million. #resist |
