[molpro-user] weird issue with MOLPRO 2010.1 binaries

Dear Jan,

Generally speaking, if molpro binary works on one node of the cluster
locally, it should work on a single node via PBS, too. I have tested it
via PBS on our cluster, and I haven't seen such problem.

Could you check how your PBS works?

For example, if rsh is disabled, when you start binary molpro on head
node but want to run on other node of the cluster like

molpro -N comartin:cfa082:4

This can't work because molpro has to login in the node cfa082 by rsh,
and then runs.

Best wishes
Manhui
