Well, I've encountered what appears to be some sort of issue running the Collatz project. My GTX580 was running at about 88% and when I just checked it (via EVGA Precision), the GPU Usage has gone basically to zero. I tried perusing the Collatz forums, but didn't really see anyone describing this problem. The BOINC Manager GPU setting is set to "run always", I don't see any errors being reported, the (4) WUs are still running, progress %'s are still incrementing, but I can't believe they will get very far with the 580 showing no usage in Precision. I'm running BOINC 6.12.34 on that Rig with the Nvidia driver 285.62. Anyone have an idea as to what I could/should do? This is my first real experience with BOINC GPU work as well. Edit:
Ok, think I figured out the problem. Collatz can send you both CPU and GPU WUs (I didn't realize that). The Collatz WU's that I thought
were running on my GPU were in fact CPU WUs. Those WU's that I believe are CPU units were titled "mini_collatz 2.00 (sse)". I found a discussion thread which led me to go back into my Collatz profile and set the "Use CPU Enforced by version 6.10+" to "no". I already had set the "Use NVIDIA GPU Enforced by version 6.10+" to "yes" when I first setup my profile. http://boinc.thesonntags....thread.php?id=596#9674
After making the change above, low and behold, the next Collatz WU that I received was titled "collatz 2.03 (cuda 23)". Also in the "Status" column of Boinc Manager, the status for that GPU WU is titled "Running (0.01 CPUs + 1 NVIDIA GPU)" instead of just "Running" as it shows for the Collatz CPU WUs that are running. Checking EVGA Precision, my Usage is running at 81%, so all looks to be OK now.
