Basic fairshare for HPCWorks PBS Professional

Managing HPC cluster resources is challenging. By default, in HPCWorks™ PBS Professional™, all users can access the entire cluster without restrictions. Administrators can create walled-off spaces for each user, but this leads to inefficient resource utilization. Similarly, traditional scheduling methods like priority-based, first-in-first-out or time-based each struggle to satisfy diverse user needs, often wasting resources, extending completion times and creating unfair distribution of computing power.

HPCWorks PBS Professional fairshare solves this problem by allocating cluster resources based on usage history and a weighted tree structure. It's the most direct way to grant users a percentage of cluster resources while ensuring fair, equitable access. The scheduler automatically balances requested and used resources to match fairness expectations as quickly as possible, giving everyone what they "deserve" based on their contracted allocation.
