Hi,
I have d'loaded and built 6.8 with various compiler options and I wanted to profile the various exes
so am trying to run an example in serial. The instructions I have found for serial say to simply
run the nwchem executable with an input file but I just get the following
$> nwchem Input_c240_pbe0.nw
[0] Received an Error in Communication: (1) there must be at least two ranks per node
MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 DUP FROM 0
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.
If I try it as mpirun -np 1 nwchem Input_c240_pbe0.nw I get the same.
Is there a way to build it to be able to run in serial ?
