Hi,

I'm trying to start a program developed with the MPI library and using
at
the same time the "nohup" command inorder 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 lougout 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 uning 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.
Finally we use MIPSPro 7.2 Compilers (patched) and I use ksh shell.


Thanks,

Martin
