[mpich-discuss] No hang-up with MPICH2

[Ralph Butler]

On a linux cluster, I tried this which worked fine:
         nohup time mpiexec -l -machinefile tempmf -n 2 hostname < / 
dev/null &
I also replaced hostname with "cat -" just to see if requiring stdin  
made any difference.
Since I was using tcsh, I switched to sh to what happened.  It still  
worked fine although
the output went into a file (nohup.out) instead of to stdout.
