I use the following command to start my job (scode): nohup mpirun -np 8 ./scode x2f > scode.out 2> scode.err & Unfortunately my job stop when I loug out from our parallel machine exactly as if I was not using the "nohup" command.

Hi,

I'm trying to start a program developed with the MPI library and using
at the same time the "nohup" command in order to be able to log off
from my workstation without disturbing the parallel job.

I use the following command to start my job (scode):

   nohup mpirun -np 8 ./scode x2f  > scode.out 2> scode.err &

Unfortunately my job stop when I loug out from our parallel machine
exactly as if I was not using the "nohup" command.

Im I doing something wrong  ?
Is there something special to do to use mpirun and nohup ?

I'm using an 8 CPU Origin 2000 computer from SGI.
We are using MPI 3.1.0.1 library form MPT 1.2.0.1 running on IRIX 6.4 OS
with recommended patches up to April 1998.

Thanks,

Martin
