*Original issue: https://charm.cs.illinois.edu/redmine/issues/1676* --- On Blue Waters, 200 nodes, 50 replicas (4 nodes per replica) non-smp running apoa1 is uniformly and significantly slower than a separate 4-node run. No idea...
If a netlrts-smp layer is launched using ++n with +ppn instead of ++ppn, e.g., `charmrun ++n 6 ++mpiexec ++remote-shell srun namd2 +ppn 8` then the +ppn 8 is silently ignored...
