Dear all,<br><br>We have a cluster with SMP/dual core nodes, each one has two processors with two cores each. In the nodes file we have 4 virtual processors defined.<br><br>We use to submit 2,4 and 6 processes jobs, and we find more efficient to pack the jobs into a node, because of our slow network.
<br>The 2 and 4 cases are easy and we put in our scritpt:<br><br>#PBS -l nodes=1:ppn=2 <br>#PBS -l nodes=1:ppn=4<br><br>but the case of 6, we would like to run 4 in one node and 2 in other node, doesn't run. We, following the man page, put:
<br>#PBS -l nodes=1:ppn=4+ppn=2<br><br>Any idea of how to impose that configuration?<br></blockquote></div><br>#PBS -l nodes=1:ppn=4+1:ppn=2<br>
