usually I use a "cheap" master node when I'm running starcluster on spot instances.
And usually, I launch my jobs with that kind of command :
qsub -b y -cwd -pe orte 24 mpirun ./mpi-executable arg1 arg2I 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.
