====== How can I check what resources my finished jobs used? ======

Knowing what resources your jobs //actually// used is key to requesting the optimal resources for future jobs.  A quick and easy option is ''seff''

<code>
$ seff 1234567
</code>outputs<code>
Job ID: 1234567
Cluster: comet
User/Group: user/cometloginaccess
State: COMPLETED (exit code 0)
Nodes: 1
Cores per node: 4
CPU Utilized: 00:00:40
CPU Efficiency: 55.56% of 00:01:12 core-walltime
Job Wall-clock time: 00:00:18
Memory Utilized: 185.09 MB
Memory Efficiency: 1.13% of 16.00 GB
</code>

You can check individual job steps  with the syntax ''seff job-id.job-step''   e.g. ''seff 1234567.2''

You can dig deeper with the much more flexible ''sacct'' command

Find the memory used by one job with ID <job ID>

<code>
sacct -j <job ID> --format JobID,start,elapsed,state,alloccpus,ReqMem,MaxRSS,AveRSS --units=g
</code>

Find out which nodes your jobs ran on
<code>
sacct --format=User,JobID,partition,state,time,elapsed,nodelist
</code>
