Sockeye's Transition to Slurm: Completed October 31, 2023
UBC ARC Sockeye made an important change in its job scheduling system.
Effective October 31, 2023, Sockeye transitioned from OpenPBS to Slurm, aligning with the national standards set by the Digital Research Alliance of Canada (the Alliance).
What is Slurm?
Slurm is an industry-standard, open-source job scheduler and workload manager widely used in high-performance computing environments. It provides researchers with more sophisticated control over their workflows and resources, enhancing efficiency, scalability, and flexibility.
Why the Change?
The move to Slurm allows UBC researchers to:
- Utilize tools and workflows developed across various research centers.
- Benefit from improved resource management.
- Ensure compatibility with national and international research computing platforms.
- Streamline job scheduling with state-of-the-art technology.
What You Need to Know:
- Existing Scripts: Most PBS-based scripts will continue to function, but some adjustments may be required.
- Software Recompilation: Researchers must recompile any software built using supplied MPI libraries.
