Fatal error in MPI_Comm_dup: Invalid communicator, error stack:

Any help?
Not sure.
Your MPI implementation might require you to launch programs with
"mpiexec" or "mpirun -np 1" or only after starting an "mpd" daemon; if
the former requirement is the problem then you can put any prefix
commands into a "LIBMESH_RUN" environment variable to automatically
use them from the Makefile.
