I asked this question just a few days ago and Pavan suggested the following which worked for me:<br><br><br>host/hosts/hostlist is a global parameter that affects all executables. Can you try this:<br>
<br>
% mpiexec -hostlist node01:5,node02:4,node03:2 -n 5 ./exec1 : -n 4 ./exec2 : -n 2 ./exec3<br>
