Jed, yes, I'm on petsc-maint and I see this thread now. Thanks; I'll take a look. (I've had a crazy day and have been more behind than usual on email.)

No one has made a serious effort to use any other compilers but Gnu (at least not publicly).

Is this just because this code predates support for other host compilers with nvcc, or is there perhaps some more subtle reason that I, with my inexperience using CUDA, don't know about? I'm guessing that I just need to add support for using '-ccbin' appropriately to set the location of the non-GNU host compiler, but maybe there is something that I'm missing. I poked around in the petsc-dev mailing list archives and can find a few old threads on using non-GNU compilers, but I'm not sure what conclusions were reached. Best regards, Richard
