Re: Fwd: StarCluster Digest, Vol 44, Issue 5
Hi Rajat,
Yes. It´s OK.
In one of my tests, the cluster has been shutdown still working.
The main diff is that I use MPICH2 instead of openMPI. I don´t know if this
change anything.
But I will run some new tesst and return the results to you all.
All the best,
Sergio
