[molpro-user] parallel excustion problem

[Cimiraglia Renzo]

Hello,
answering Jörg Saßmannshausen's question, I find that the following works
for me. Supposing you have two different nodes, node1 and node2, each with 8
processors, you could invoke molpro this way:   molpro -n 16 -N
jorg:node1:8,jorg:node2:8 jobname.com
where jorg, say, is the username with which the nodes are accessed.
Hoping this helps,
                                                            regards
                                                           Renzo
