I also find it odd that projects were working before for and now is no longer working and projects that weren’t working for me are working now? I know you say the algorithm hasn’t changed but what did change between then and now? Surely, some bug fixes? I know I let RC send crash reports for many of my crashes.
Also, as a developer of CUDA based programs and a speaker at GTC, wouldn’t you want to lobby NVidia to provide better reporting for this type of failure? I mean “unknown error” isn’t really acceptable. If the driver restarted because of thermal fail safe, then it should report as such. The projects I have run recently are running at the SAME temp as they were when they were failing. I ran a project for 6 hrs a few nights ago with sustained temps, it didn’t give up on me.
I would say, provide with an earlier build and have him test it. Sometimes seemingly unrelated things are indeed related.
BTW, I am happy to have stability now, I am just the type of person that wants to know how and why something works
