Two things: 1. It looks like you are using the MPICH implementation of MPI. You should probably ping them on their email list -- this list is for the Open MPI implementation of MPI (a wholly different code base than MPICH; sorry!).
2. The error code seems quite descriptive, actually: > MPI_Send(176): MPI_Send(buf=0x7fffa7a1e4a8, count=1, MPI_DOUBLE_PRECISION, > dest=1, tag=1, MPI_COMM_WORLD) failed > MPI_Send(98).: Invalid rank has value 1 but must be nonnegative and less than > 1 You sent dest=1, but the apparently the communicator must be of size 1, meaning that the only possible destination is 0 (i.e., yourself).
