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.
