Summary

This tutorial introduces the process of scheduling jobs on the OU (University of Oklahoma) supercomputer, named Oscar. The presenter explains how to log in via SSH to the Schooner cluster, emphasizing load balancing and the use of dedicated data transfer nodes for large transfers. He describes the different node types: login nodes for configuration and testing, and compute nodes for actual experiments, which must be accessed via the SLURM job scheduler. Storage options are covered, including home directories for persistent but limited storage, and scratch space for temporary large data. The video details the use of SLURM commands like sbatch, squeue, and sinfo, and explains how to write batch files with resource requests (partition, CPUs, memory, time) and execution commands. It also demonstrates how to run job arrays for parallel experiments. Best practices are emphasized, such as testing locally, avoiding server execution on login nodes, and being considerate of other users. The tutorial includes a simple example using Python with TensorFlow/Keras, and concludes with tips for efficient resource usage and debugging.
