Unless you're lucky and you have a dedicated cluster that is completely under your control chances are that you will have to use SLURM to timeshare the GPUs with others. But, often, if you train at HPC, and you're given a dedicated partition you still will have to use SLURM.
The SLURM abbreviation stands for: Simple Linux Utility for Resource Management - though now it's called The Slurm Workload Manager. It is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters.
