Hi again,

I have finally installed LAM and compiled a program which outputs:

MPI_Comm_size: invalid communicator: Invalid argument (rank 0,
MPI_COMM_WORLD)

MPI_Comm_size: invalid communicator: Invalid argument (rank 1,
MPI_COMM_WORLD)

Rank (1, MPI_COMM_WORLD): Call stack within LAM:

Rank (1, MPI_COMM_WORLD): - MPI_Comm_size()

Rank (1, MPI_COMM_WORLD): - main ()

MPI_Comm_size: invalid communicator: Invalid argument (rank 0,
MPI_COMM_WORLD)

Does anyone have any idea why this could be hapenning?
