Hi Hyokun,

Im a user of MPICH2 and OGE.

It seems that youre using $fill_up instead of $round_robin. If so, try to
change it to $round_robin with $ qconf -mp orte
You can learn more here:
http://star.mit.edu/cluster/docs/latest/plugins/sge.html#using-the-plugin

Let me know if this help you.

All best.

Sergio
