WebbThe higher the priority your job is assigned, the more likely it is to run sooner. We have implemented the Slurm Fairshare feature. Basically, how this works is that the more you use Falcon - the lower priority your jobs have when compared to a user that has not been using as many compute resources. WebbSLURM on DeepThought uses the ‘Fairshare’ work allocation algorithm. This works by tracking how many resource your job takes and adjusting your position in queue depending upon your usage. The following sections will break down a quick overview of how we …
