Hi all,<br><br>usually I use a "cheap" master node when I'm running starcluster on spot instances.<br><br>And usually, I launch my jobs with that kind of command :<br><pre>qsub -b y -cwd -pe orte 24 mpirun ./mpi-executable arg1 arg2</pre>I was wondering, how could I exclude the master node from the list of nodes running the job. Since the master node is slower in my case, it clearly affects the efficiency of the computation.<br><br>Cheers<br><br>JP<br> </div></body>
