21) Message boards : Number crunching : AMD GPU Computation errors (Message 59227) Posted 5 Jul 2013 by Michael Yusko Post: Lately, everything I crunch comes up Computation Error. I only crunch with the GPU. AMD Radeon HD 6950 2GB. Thoughts? Thanks.
22) Message boards : News : New N-Body (Message 57121) Posted 1 Feb 2013 by Michael Yusko Post: Linux64: Utilizing ".05 CPUs + 1 ATI GPU" in reality, a single nbody_100k task is using 156% cpu (1 task is maxing out both CPU cores) Granted they are only taking 2 - 20 minutes each to process, but they are not utilizing the GPU at all.
23) Message boards : News : New N-Body Runs (Message 57015) Posted 24 Jan 2013 by Michael Yusko Post: My preferences are to allow MilkyWay@Home GPU computation only. I utilize both CPU threads on this machine for Seti@Home. It should never accept any CPU tasks from MilkWay@Home on this machine. As you stated it appears it was improperly deployed. This runs on a Slackware 14.0 64-bit system. I also have a 2 Debian Testing machines, 1 64-bit (Dual Xeon) and 1 32-bit (Pentium M). Neither have a GPU capable of project computing. I'd be happy to provide any feedback and information I can, just tell me what you want to know. I've thought about picking up a decent GPU for the Xeon but being a server, I'm limited to PCIe 1x and there aren't any DP GPUs available. (I think the top GPU I can get for it would be a HD5450) It has a Voodoo3 2000 PCI in it right now because that is far better than the Rage XL residing onboard. But I digress. As I said, if you want Linux feedback, let me know.

24) Message boards : News : New N-Body Runs (Message 57007) Posted 24 Jan 2013 by Michael Yusko Post: According to what I am seeing in BOINC Manager, it says N-Body is using .05 CPUs/1 ATI. (It tells me it is utilizing the GPU) If it is not using the GPU like you say, then it is trying to simultaneously compute on a CPU thread against another project task. Hmmmmmm.
25) Message boards : News : New N-Body Runs (Message 56996) Posted 23 Jan 2013 by Michael Yusko Post: Normal Milkyway@Home 1.02 runs a workunit every 1 minute and 36 seconds using 92% of my GPU. N-Body takes ~5hours???? using less than 1% of my GPU??? Is this supposed to be normal?
26) Message boards : Number crunching : Boinc won't detect my GPU (AMD/Linux64) (Message 55055) Posted 10 Jul 2012 by Michael Yusko Post: I posted on the regular boinc forums and got my answer. http://boinc.berkeley.edu/dev/forum_thread.php?id=7681#44805 FYI, now that it's running, a work unit that took my CPU ~2 hours and 20 minutes to complete, takes my GPU ~1 minute and 50 seconds to complete. And it's only using 90% of the GPU.

28) Message boards : Number crunching : Boinc won't detect my GPU (AMD/Linux64) (Message 54865) Posted 24 Jun 2012 by Michael Yusko Post: I've been using BOINC for a long time but up until now I've never had a GPU able to crunch with. I just purchased an AMD Radeon HD6950 2GB and I can't get BOINC to detect my GPU. I tried following the directions for GPU computing with Linux, but I can't seem to make it work. As soon as BOINC loads it says "No usable GPUs found." I've tried it with both AMD's 12.4 and 12.6 Beta drivers and all sorts of options in the cc_config.xml file. Perhaps I'm missing something? I'm running BOINC 7.0.25 with the 2.6.37.6 kernel. Thanks.
