[mpich-discuss] mpirun not running in batch mode.

[Gilles Gouaillardet]

Francisco,

this is fine, i just wanted to double check you were not using a
machinefile the wrong way.

your initial request was :

and from what i can read, you are not using any machinefile.
how do you expect your job run on all the cluster nodes if you do not
have a machinefile ?

can you run
$ruta_mpi/mpirun -n 40 hostname
both from shell and crontab

which nodes are used in both cases ?


by the way, can you ssh passwordless on all the nodes from where the
cron is ran ?
passwordless means you do not need to enter any password and/or
passphrase nor "save" your passphase via ssh-agent.

and could you confirm
/home/meteo/RAMS/SCRIPTS/RAMS_operatiu.bash  < /dev/null

works fine from the shell ?

Cheers,

Gilles
