Hello,<br>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 <a href="http://jobname.com">jobname.com</a><br>
where jorg, say, is the username with which the nodes are accessed.<br>Hoping this helps,<br> regards<br> Renzo<br>

Hi all,<br>
<br>
jumping into that discussion, whereas I understand the -n option, I somehow<br>
could never really work out how to supply a hostlist for Molpro when I want<br>
to run a job at different nodes. I am wondering if that was the original<br>
question as well?<br>
<br>
All the best<br>
<br>
