Francisco, from the shell, can you try to run /home/meteo/RAMS/SCRIPTS/RAMS_operatiu.bash < /dev/null and confirm everything works as expected ? also, i cannot see any machinefile. is /home/meteo/RAMS/RUN/RAMSIN.operatiu your machinefile ? if yes, can you replace $ruta_mpi/mpirun -n 40 ./rams60 -f /home/meteo/RAMS/RUN/RAMSIN.operatiu

$log-INITIAL-$hoy-$horasim

with $ruta_mpi/mpirun -n 40 -f /home/meteo/RAMS/RUN/RAMSIN.operatiu ./rams60

$log-INITIAL-$hoy-$horasim

and give it a try (both from shell and crontab) Cheers, Gilles
