The good news is it builds. The bad news is that it doesn't function properly. This same code works fine with cuda 4.0, so I'll have to dig deeper to figure out where it is going wrong. I tried running one of the examples and it worked with sacusp, so perhaps something isn't working right in my code.

Not yet. But I'm considering it.

Has anybody tried compiling petsc-dev using CUDA 4.1? I'm just wondering if I should bother trying.

Thanks, John
