Hi Lev,

Thanks for the reply. I have not tried to compile Charm++ with any MPI
implementations, and been using the net- option. Is there any
advantage of using MPI (just any MPI)vs. using the net- option?

Best regards,

As a binary you probably won't be picking up the performance benefits, which should be determined by whatever you're using as message parsing interface (OpenMPI?). Then you should seem some real gains.
