Sorry for jumping in late.
I was able to use ~128 SGE slots for my test run, with the either of the
SGE allocation rules ($fill_up or $round_robin) and -np 64 on my test
MPI program, but I wasn't able to reproduce your error though on
Solaris. Like Brian said, having the stack trace could help. Also, I
wonder if you can can try with a non-MPI program, a smaller number of
slots, or -np to see if he's still able to see the issue?

I am trying to setup SGE to run DLPOLY compiled with mpif90

general I am much more luckier running DLPOLY interactively then
using SGE. The error that I got is: Signal:7 info.si_errno:0
(Success) si_code:2()[1]. A previous message in the list[2], says
that this is more likely to be a configuration problem. But what
kind of configuration? It is in the run time?
Could you include the entire stack trace next time? That can help
localize where the error is occurring. The message is saying that a
process died from a signal 7, which on Linux is a Bus Error. This
usually points to memory errors, either in Open MPI or in the user
application. Without seeing the stack trace, it's difficult to pin
down where the error is occurring.
Another error that I got sometimes is related with "writev"[3]
But this is pretty rare.
Usually these point to some process in the job dying and the other
processes having issues completing outstanding sends to the dead
process. I would guess that the problem originates with the bus
error you are seeing. Cleaning that up will likely make these errors
go away.
