Primary job terminated normally, but 1 process returned

mpirun noticed that process rank 6 with PID 0 on node gnode1 exited on signal 8 (Floating point exception).

It seems that there is no lamd running on the host gnode1.

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.

Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

Thank you in advance
