Dell Precision 530 + MPICH

a)The machine is a Dell Precision Workstation530 (SMP Intel Xeon 1.7Ghz
running Redhat 7.2 kernel 2.4.17).
When the "poweroff" command is issued on the UP mode everything works
fine: the machine is turned off.
It's another story for the SMP mode (kernel smp loaded instead): all
the unmounting stuff, stopping services run smoothly but the machine
waits for me to push the power button to switch it off.
Any ideas? I already tried the apm=power-off option at the boot
b) SunGridEngine is the scheduler used on our cluster. Most of the users run
using MPICH libraries. How can I prevent users to run MPI
interactively and to bypass the scheduler? Should I write a script that checks
every jobs on the nodes and kills the 'bad' ones? Is there any MPICH 'wrapper'
Does my question make any sense?
Thank you for any information/suggestion.
