[SCore-users] suspending jobs

[Atsushi HORI]

Hi, Nick,

How is everything going ?

>Can I send SIGSTOP/SIGCONT to a process to suspend / resume say a 
>SCore PBS job  or is this only possible in multi-user mode ?

If you send a SIGTSTP (not SIGSTOP) or SIGCONT signal to the scrun 
process, then the parallel job will be suspended or resumed, 
regardless to the scheduling mode.

# this is what I try to program and I believe it works :-)

If you send SIGSTOP, however, then only the scrun process is 
suspended, because, in Linux (and Unix), there is no way to catch the 
SIGSTOP signal.

So tha problem is how can you send SIGTSTP/SIGCONT in a batch job 
scheduler.
