Hello,

I used the great howto for a tight integration of mpich2 and sge made by 
reuti :
http://gridengine.sunsource.net/howto/mpich2-integration/mpich2-integration.html

I'm using solaris 10, x86 and sparc. The job are correctly spawned on 4 
nodes :

Just on one node :
Sara06-jobic% ptree 21175
455   /opt/sge/bin/sol-amd64/sge_execd
  21169 sge_shepherd-2576 -bg
    21170 /opt/sge/utilbin/sol-amd64/rshd -l
      21171 /opt/sge/utilbin/sol-amd64/qrsh_starter 
/opt/sge/Huit/spool/Sara06/active_jobs/
        21172 tcsh -c /opt/lib/mpich2/bin/smpd -port 22576 -d 0
          21173 /opt/lib/mpich2/bin/smpd -port 22576 -d 0
            21174 /opt/lib/mpich2/bin/smpd -port 22576 -d 0
              21175 /home/jobic/sge/exemple/./hello

However, when the job is finished, there's still the smpd running :
Sara06-jobic% ptree 21171
455   /opt/sge/bin/sol-amd64/sge_execd
  21169 sge_shepherd-2576 -bg
    21170 /opt/sge/utilbin/sol-amd64/rshd -l
      21171 /opt/sge/utilbin/sol-amd64/qrsh_starter 
/opt/sge/Huit/spool/Sara06/active_jobs/
        21172 tcsh -c /opt/lib/mpich2/bin/smpd -port 22576 -d 0
          21173 /opt/lib/mpich2/bin/smpd -port 22576 -d 0

With a qdel, i can delete them :
  2576  4 mpich2_test               jobic      09/03/2008 13:38:00 
Huit       (stalled)
It's just taking some time.

Do you know why this strange behavior is happening ?

Many thanks,

Yann jobic
