I bet you (1) Siesta doesn't check MPI return codes and (2) Siesta has no way to handle node failure. I bet it can't even handle malloc returning NULL. If a node fails more than once a month, the hardware is bad and you should buy new stuff. Jeff Sent from my iPhone

Okay Pavan. I'll try that. Then I'll return the result. Thank's. Julio.

Hi Julio,
There are two steps needed for this:
1. You need to tell your MPI application to return errors instead of aborting.
2. Tell the process manager to not clean up your remaining processes when one of the processes dies.
Details on both these steps are listed in the "Fault Tolerance” section of the MPICH README. Please try it out and let us know how it goes.

I am using mpich-3.0.4 on cluster with 7 nodes running the latest version of siesta. My problem is that when a one node goes down, the siesta and mpich stops running and giveserror. How do I get when a node falls, siesta and mpich continue to run? Thank's. Julio.
