An important use case for us is, in fact, these VIP queues :) Here is a link to the documentation, including tests, configuration and howtos: https://github.com/ciemat-tic/codec/wiki/Slurm-DMTCP [https://avatars0.githubusercontent.com/u/8639317?s=400&v=4]<https://github.com/ciemat-tic/codec/wiki/Slurm-DMTCP> Slurm DMTCP · ciemat-tic/codec Wiki · GitHub<https://github.com/ciemat-tic/codec/wiki/Slurm-DMTCP> github.com Intro. This document presents a complete description on the integration of Slurm and DMTCP. It includes installation, configuration and testing. cheers, Manuel 2018-01-25 17:18 GMT+01:00 Brian Novogradac <brian.novogra...@utoronto.ca<mailto:brian.novogra...@utoronto.ca>>: Thank you for your input! Would any of you have an example on how you setup the conf file for the queue using the QOS method? I'm reading the QOS docs as I type.

You can set up a QOS 'vip', which can preempt other QOS. We don't preempt, but use multifactor priority with various QOS with different priority values. In that case, VIP jobs won't start immediately, but just get pushed to the front of the queue. On the other hand, no CPU-time is lost due to low-status jobs being terminated early due to preemption (although if the low-status jobs are able to do some form of checkpointing that will be less of an issue). Depending on how pushy your VIPs are, they might go for a preemptionless solution, too.
