Thank you for replay,

I'm working on cluster with 10 nodes and 400 processors. NWchem was compiled from sistem administrator of cluster. Which information I'll ask about?

The full input file is:

start pchg_trimpolys4
title "Point Charge trimpolys4"

permanent_dir /home/scurcio/qm/prova/tmp
scratch_dir /home/scurcio/qm/scratch

memory stack 2000 heap 1000 global 5000 mb

In single-node submitions the job works. Otherwise, when i perform multi-node work I obtain divergence during DFT energy iterations.

Thanks,
Frank
