MPI Problems

Hi Everyone

I want to run Reaxx in lammps.I have compiled the Reaxx sucessfully,
but when I run, the error occurs like this:

Fatal error in MPI_Comm_rank: Invalid communicator, error stack:
MPI_Comm_rank(106): MPI_Comm_rank(comm=0xbf1ea0, rank=0x61509510) failed
MPI_Comm_rank(64).: Invalid communicator

I think it is the MPI problems. I cannot solve this. Thank you very much!

Thanks

but nobody else will be able to solve it either with so little information!
most likely you are mixing two different MPI libraries when compiling LAMMPS.
and that would actually not be an MPI problem, but a case of PEBCAC.
