A temporary workaround is to just run in serial for now. The increased
throughput of pmemd.cuda.MPI is so low that it's not worth waiting for a
fix to come out instead of running in serial instead.

Indeed, the 'fix' may simply be that we put in another check to provide
a useful error message (depending on what exactly your system is).
