What is QOS (quality of service)?

At CCR we are using the quality of service function of the SLURM scheduler in two ways.  The first is to set limits on number of jobs users can submit.  To keep things fair for everyone, the most jobs a user can have in the general-compute and scavenger partitions at one time is 1000.  We limit the largemem, gpu, and viz partition jobs to 32 and 4 is the max you can submit to the debug queue.  We also use QOS to offer those who financially support our center a priority boost.  In theory this isn't any different than it was before, except all of these limits were set on associations and by organizing it this way, we've eliminated 75% of our associations.  It also gives us the flexibility in the future to use QOS in other ways.  See the list below for all the possible qos's available on CCR clusters.  Your account has been given access to the ones we believe you should have.  If you find an error, please submit a help ticket. 

List of CCR QOS settings:

supporters = priority boost available to financial contributors to CCR (How do I become a CCR supporter?)

scavenger = includes all scavenger partitions in industry, chemistry, MAE, & physics clusters - available to academic users only

debug = ub-hpc cluster, debug partition, maxSubmitJobsPerUser=4  - available to academic users only

largemem = ub-hpc cluster, largemem partition, maxSubmitJobsPerUser=32  - available to academic users only

gpu = ub-hpc cluster, gpu partition, maxSubmitJobsPerUser=32 - available to academic users only

general-compute = ub-hpc cluster, general-compute partition, maxSubmitJobsPerUser=1000  - available to academic users only

industry = industry cluster, industry partition, maxSubmitJobsPerUser=1000  - available to industry users only

viz = available only through the OnDemand Portal - NOTE: any jobs submitted directly to this partition will be rejected.  You must use the portal
