[farmshare-discuss] maximum memory for an interactive job on Farmshare 2?

Hey Jamie,

This isn't a perfect metric, but if you go to oss.stanford.edu/job-maker
you can select cluster "farmshare2" and partition "normal" and quality of
service "Interactive" and then enter a value enter memory, click generate
to get the job file, and if it's over the limit it will give you a message
in a blue bar at the top (see screen shot below)

I'm not sure if that helps, but maybe?

Best,

Vanessa
