It looks like you have a version mismatch of LAM/MPI between your two
nodes. The error message is telling you that it found two different
versions of the lamd RPI on two nodes:
MPI_COMM_WORLD rank 0: lamd (v7.1.0)
MPI_COMM_WORLD rank 2: lamd (v7.0.0)
Your laminfo is showing that you have 7.1.3 installed on both nodes,
but you might want to check for PATH differences on non-interactive
logins.
