problems with running CAM on multiple processors

[maisa@dgf_uchile_cl]

Hello,
I am trying to run CAM on a Linux cluster. The model compiles, and
seems to run fine as well. but the are no output files produced!!!
The model runs ok on 1 processor

Here are the steps I followed:

$cfgdir/configure -spmd -test

thats ok, I then get the namelist in run with:


$mpirun -np 4 $blddir/cam < namelist
where:
set mpirun = /opt/scali/contrib/mpich/bin/mpirun

the only output to screen I get is:

running CAM in /export/home/andes/maisa/CAM3.0/runs/parallel
t_setoption: option disabled: Usr Sys
t_setoption: option disabled: Usr Sys
t_setoption: option disabled: Usr Sys
t_setoption: option disabled: Usr Sys

in the run directory the following files appears: PI32062


andes 0 /export/home/andes/maisa/CAM3.0/runs/parallel/bld/cam
node-11 1 /export/home/andes/maisa/CAM3.0/runs/parallel/bld/cam
node-12 1 /export/home/andes/maisa/CAM3.0/runs/parallel/bld/cam
node-13 1 /export/home/andes/maisa/CAM3.0/runs/parallel/bld/cam

I logged into the nodes and the seems to be something running, but
there is are no output files!!!

PD: I tried with mpimon as well, but the the processes never starts!
