[mvapich-discuss] Fatal Error in MPI_Init

[Lockwood, Glenn]

The operative error is "Connection refused," and I assume you used mpirun_rsh, so it sounds like you don't have ssh configured properly between your two nodes.

Hi there,

I'm new with MVAPICH2. I built a cluster with 2 nodes. When I run a distributed parallel task, I got the error message below.

Please help me to find the cause.

Thanks in advance.
