[slurm-users] using resources effectively?

[Weijun Gao]

Hi,

Say if I have a Slurm node with 1 x GPU and 112 x CPU cores, and:

     1) there is a job running on the node using the GPU and 20 x CPU cores

     2) there is a job waiting in the queue asking for 1 x GPU and 20 x 
CPU cores

Is it possible to a) let a new job asking for 0 x GPU and 20 x CPU cores 
(safe for the queued GPU job) start immediately; and b) let a new job 
asking for 0 x GPU and 100 x CPU cores (not safe for the queued GPU job) 
wait in the queue? Or c) is it doable to put the node into two Slurm 
partitions, 56 CPU cores to a "cpu" partition, and 56 CPU cores to a 
"gpu" partition, for example?

Thank you in advance for any suggestions / tips.

Best,

Weijun
