Hi Shyamniper —

It is possible to include the master node in the working partition. In step 5.3.5 (in part I), you would just modify the partition definition to include the master node:

PartitionName=mycluster Nodes=node[02-04] Default=YES MaxTime=INFINITE State=UP

becomes

PartitionName=mycluster Nodes=node[01-04] Default=YES MaxTime=INFINITE State=UP

You should be able to get doParallel and parallel working. It looks like parallel makes use of the Snow package under the hook, which I think uses OpenMPI for scheduling, which I run through setting up in part III of this series.
