Jes, read up on kprobes a little if you think its of no use in these
kind of situations. A systemtap script to count/measure alignment fault
rates and see who is causing the load isn't very hard to write.

But this does make sense ... the system administrator of a mainframe or
super-computer can (and arguably should) be monitoring resource
utilization and providing feedback to users on how to get the best
performance from their applications.

Actually perfmon would probably be better suited for this on ia64 than
kprobes/systemtap. You can do it on hackish way with a [jk]probe, but it
isn't going to be all that pretty.

Nuke it!
