hi does any one know about this error :
Fatal error in PMPI_Comm_rank: Invalid communicator, error stack:
PMPI_Comm_rank(108): MPI_Comm_rank(comm=0x0, rank=0x7fff24a405bc) failed
PMPI_Comm_rank(66).: Invalid communicator
Fatal error in PMPI_Comm_rank: Invalid communicator, error stack:
PMPI_Comm_rank(108): MPI_Comm_rank(comm=0x0, rank=0x7fff63e1598c) failed
PMPI_Comm_rank(66).: Invalid communicator

it is when i run mpich like :
mpirun -np 2 ./coawstM   swan_only.in

i don't know if this is a problem in my executable file (coawstM) or this
is from mpich or any other hardware issues or anything else
thank you for your help
nazi
