I’m running a GT710 - it takes maybe 10 hours per task but it does get there and only adds about 4 watts to the power drain.

I have “Do work on GPU when computer is in use” and “Use xxxx graphics card if possible” set to yes.

The 730 just finished it's first opng, 5 hours.

I had another workunit fail. The error from the Boinc manager was "31/03/2024 12:08:42 | World Community Grid | Output file OPNG_0225454_00129_0_r2030031496_0 for task OPNG_0225454_00129_0 absent".

The start of the results log is as follows:

One thing I noticed is that the folders c:\projects and c:\build don't exist. I don't think that's relevant as the debug process has already started by then but I'm not sure.

Does anyone know if I'm correct that the missing output file is as a result of the issue and not the cause of it? If my Anti Virus was causing an issue it would also affect cpu units? CPU units work OK.
