[ONLINE] Adopting SLURM: Transitioning from PBS Scheduler (EuroCC)





SLURM is a workload manager used to allocate jobs on Barbora and Complementary systems. It will also be used on Karolina since September 2023. 

This introductory course is designed to help the users seamlessly migrate from the PBS scheduler to this newly installed job management system. The course describes the SLURM fundamental concepts, its job submission process, terminology, and environment variables. 

Benefits for the attendees, what will they learn

After the course, attendees should be able to efficiently create, submit, monitor, and manage computational jobs using SLURM efficiently. The special focus will be on describing the differences between PBS and SLURM and how to transform PBS scripts into SLURM.






Basic knowledge of Linux, Unix, bash, and HPC infrastructure. Attendees will be provided with training accounts on HPC clusters and can try out the demonstrated features.
