It *should* work but it really depends on if pgi fixed any of the libnuma problems we complained about years ago. They have (had?) an internal broken version of libnuma they use for their OpenMP stuff. We had to build with -Mnoopenmp to get it to work at all. I got so fed up with pgi that I dropped all support for using it with Open MPI on Cielo. That said, now that pgi is part of nvidia things may be better now. I would check with HPC-3 and see how they build with pgi on our other systems. -Nathan
