Topic: Navigating PBS to Slurm Migrations in Production Environments In the realm of High-Performance Computing (HPC) system administration, batch computing is the primary mechanism by which researchers make use of the system. Batch workloads are almost always processed by a resource scheduler, which dictates the commands and syntax that researchers leverage to submit their workloads. Resource scheduler requirements can evolve over time, necessitated by user needs, changes in vendor posturing, and other dynamics. For this meeting we’ll hear from two leading institutions that have undertaken migrations from PBS to Slurm on significant HPC systems that were in production. Our first presenter will speak to their technical execution of a seamless migration that went largely unnoticed by end-users. Our second presentation will cover an example that required more user involvement. Both presentations will touch on the required change management, as well as their approach to end-user communications.

Speakers:
Ryan Cox, Brigham Young University
Roman Baranowski, Ken Bigelow & Jacob Boschee, University of British Columbia
