I've never seen such a thing, and I'm not even sure what PyCUDA could do to cause a hard crash a machine like that. It sounds like either a driver or hardware bug to me. If there's something that PyCUDA can do to avoid the hard crash, I'd be more than happy to do that--but I'm not even sure what that would be... One possible issue is threads. PyCUDA (CUDA generally, really) isn't very good around them--but that should only be an issue if multiple threads touch the GPU. As a simple test, can you may write a script that does some PyCUDA computations and then sits in a raw_input()? That's somehow the closest analog to IPython I can think of. Anyhow, these are just some suggestions. Hope some of this is helpful. Andreas
