I’m wondering what are the consequences of insufficient power fed to a GPU. We have a 4-295GTX box, and I’ve noticed that large problems always fail (i.e. GPU returns crappy result) after some arbitrary time on the GPU recognized by CUDA as #7. Always on GPU 7, no matter what CPU thread is mapped to it. So I have several ideas why it happens –
sounds like it is not a bug because the problem doesn’t depend on the CPU-GPU mapping
lack of power
? BIOS issue
? something else
which one in you opinion is the most probable?
