Just for clarification in my original post:

Putting /home on the parallel filesystem isn't so much because I think 
my users are idiots. It's because I like to remove as many 'barriers to 
adoption' as possible and help them to 'cross the chasm' and become 
cluster users. I often get help e-mails from new users with error 
messages about not being able to access the executable on the compute 
nodes. This e-mail is often sent a Friday evening, so they have to wait 
until Monday morning for me to get back to them.

I try to do everything I can to make using clusters as easy as possible 
for my users. Once they get the hang of the basics and can run simple 
jobs, then I can worry about teaching them the difference in the 
performance of different filesystems, etc.
