[slurm-users] How to set priorities of actual obs

[Dmitri Chebotarov]

Hi Ketiw, 

Wouldn't 'nice' work in this case?

$ man nice
...
NAME
       nice - run a program with modified scheduling priority

SYNOPSIS
       nice [OPTION] [COMMAND [ARG]...]
...

In your submit script you would run the program as

nice -n 19 <program-name>

Please write to the list, rather than to me directly.

I think you can probably achieve what you want with cgroups, but I have no experience of doing this myself.
