How to specify RAM limit for job

[chengyangit]

Hi
I was trying "-l mem=..." to specify RAM for a job and did not work. Could you please share some idea on how to solve the problem below? Really appreciate:

I was trying to run two jobs in one node. Each job request >30GB RAM at some point and the node only has 60GB RAM. So there is a possibility that one of the job get kill for insufficient RAM. I was trying set a RAM usage limit for each job and did not succeed.
