[mpich-discuss] using hydra to start a task on a specific node

[Camilo Rostoker]

I asked this question just a few days ago and Pavan suggested the following
which worked for me:


host/hosts/hostlist is a global parameter that affects all executables. Can
you try this:

% mpiexec -hostlist node01:5,node02:4,node03:2 -n 5 ./exec1 : -n 4 ./exec2 :
-n 2 ./exec3
