It has come to my attention that there appears to be a flaw in many, if not all, versions of Nvidia's 295.XX drivers.

If your monitor is put to sleep by the computer, the GPU is no longer available as a CUDA device.

This will cause an immediate failure of any CUDA WUs. This includes GFN/Genefer, PPS Sieve, GCW Sieve, and llrCUDA.

Either roll back to an earlier driver version, or configure your computer to never power down the monitor(s).

Unfortunately this behaviour also strikes all cuda projects, not only here at PG.
