The title from the original post was causing the "Recent Topics" at the left of every page to be rather wide, I inserted a space to allow it to wrap. No criticism of the poster is implied, it's just a limitation of the site code.

Using MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe I too have noticed some sets of workunits taking up the entire CPU, and taking over an hour to process.  Several hit my scheduler today.   This was on a Win2008 server running the latest NVidia drivers and 2.3 DLLs and using a GTX275.  The machine ID (for user Al Stein) is 5019936 and the workunit is 24au09ab.16409.25021.9.10.134_1_0.  (This unit should be completing within the next 10 minutes or so on that machine.)  I aborted the other units that began with 24au09ab.16409.25021.9.10.* since they were taking up too much CPU time, but let this one go to completion.

Any suggestions?

IF you see high CPU usage - look in stderr. If questions will remain, post stderr here.

resultid=1354433352 turns out to be one of those cases where the app thinks it has been told to run on an emulated rather than a real GPU, so it falls back to CPU. AFAIK there's no way to know how things got that way, for a dedicated crunching system a reboot might be recommended. Copy of the task details page attached.
