dear amber users,

I have some problems to run sander (amber 7 version) with MPI.
after a well-ended compilation on a ibm linux cluster with pgi
compiler (I used Machine.pgf77_mpi), once I run sander, I have some
errors regarding MPI_COMM_RANK, in particular:

0 - MPI_COMM_RANK : Null communicator [0] Aborting program ! --

thank you very much in advance for any answers
