gilgamesh: please limit quantum espresso and other disk-io intensive jobs

[John Kitchin]

Hi everyone,

I believe we have identified the issue that was causing gilgamesh to be
sluggish. The issue was likely a lot of quantum espresso jobs running. this
code is very disk io intensive, and was maxing out the disk write rate on
the home directories, leading to the sluggish behavior.


We are working to solve this by using local disk io on the nodes, and if we
figure that out I will let you know.

John
