Description

As pointed out on the charm mailing list, the parallel prefix no barrier example hangs when run on the mpi layer. I was able to replicate this behavior on my lab machine.

Build line: ./build charm++ mpi-linux-x86_64 --with-production -j8

It works for me on beauty with that same build command (on 1 or multiple PEs)... If you can replicate it, where does it hang?
