Hi,<div> Initially you need to form the cluster by doing the ssh passwordless login amongst the node in your cluster, then you have to create a machinefile consisting of process to node mapping and pass it to mpiexec while launching your MPI job. all the details about the creation of machinefile and job launching is given in link below. </div>

</div><div> So in your case of launching of the master process on the separate desired node can be achieved through mentioning the same in the machinefile and rest as required.<br><br>Regards,<br>-- Mahesh Doijade<br>
