Fairshare is an Altair® PBS Professional® scheduling tool designed to share a cluster’s limited resources according to history of cluster usage and the entities’ allocated percentage. Fairshare is the most direct option to grant a percentage of shared resources on the cluster to users, projects, or groups.
This white paper covers how PBS Professional collects and manages fairshare usage. With this document, you should be able to walk through each logical step of fairshare, understanding each number from pbsfs output. It also covers how you may manually alter each entity’s usage data.
