FYI, I seem to have the new GPU machine at ORNL (summitdev) working with GPUs. That is good enough for now.

Hi Mark,

ah, I was confused by the Python information at the beginning of configure.log. So it is picking up the correct compiler.

Have you tried uncommenting the check for GNU?

Yes, but I am getting an error that the cuda files do not find mpi.h.

...

I'm getting a make error.

Thanks,
