NWChem failing to run on IB nodes

Hello Edo,

thanks for the quick reply. My host file contains the following two nodes:

nxn25 1 parallel.nextscale.q@nxn25 UNDEFINED
nxn27 1 parallel.nextscale.q@nxn27 UNDEFINED

and I would like to run 16 MPI ranks on each node (32 MPI ranks in total). How should the host file be formatted?

Thanks in advance,
Wadud.
