Hi mpich users

I know I am using an old version of mpich but this one has been working for a long time so when building a new cluster we decided to use the same one. The point is that we have installed RAMS meteorological model with mpich2-1.0.5 and it runs fine when running from console but not with cron or at.

Is it running at root then or by a normal user? The path may be different when starting with these methodes too.

As it's a new cluster: did you look into the option to install a queuing system?

+1 Using cron or at to launch batch jobs is a shoot on one's own foot. A job queueing system is a clean solution, and not very hard to setup. SGE, Torque and slurm are open source/free job queuing systems that have good mailing list / community support. Gus Correa

...

If the script that runs the model is scheduled with cron it just starts processes on the main node but not in the rest of the cluster nodes.

While waiting for your help I will try to upgrade to a newer mpich version.

I can't find the reason why this is happening, probably I made some mistake. Can you help me? Any idea will be welcome and tried.

Following I attach some information that could be useful to understand my problem.
