Dear lam users,

After requested installations and configurations  for gromacs-parallel on RHEL 4.0 ,

 when I run gromacs with this command:

mpirun -n 2 mdrun_mpi -v

I have this message:

69 pc239:/home/mario/d.dppc> mpirun -n 2 mdrun_mpi -v

MPI process rank 0 (n0, p512) caught a SIGSEGV in MPI_Comm_size.

MPI process rank 0 (n0, p9663) caught a SIGSEGV in MPI_Comm_size.

Rank (0, MPI_COMM_WORLD): Call stack within LAM:

Rank (0, MPI_COMM_WORLD):  - MPI_Comm_size()

Rank (0, MPI_COMM_WORLD):  - main()

Rank (0, MPI_COMM_WORLD): Call stack within LAM:

I don't understand what it means. I only know that the program don't run. Can you help me?
Thank's in advance
Mario
