Fatal error:
The number of nodes (1) is not a multiple of the number of simulations (2)

Halting program mdrun_mpi
gcq#101: "My Heart is Just a Muscle In a Cavity" (F. Black)

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode -1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

mpirun has to be configured to use the processors you have available.
Apparently your configuration only has one processor available at the
moment. You'll need to look elsewhere for how to fix that.
