HPC Job Submission with PBS qsub

High-performance computing environments require precise resource management to run large-scale computational tasks efficiently. Understanding how to communicate with the job scheduler is the key to executing your code without wasting valuable cluster resources. This text-based course guides you through the mechanics of job submission using the Portable Batch System (PBS) environment. You will transition from running local scripts to orchestrating complex, resource-aware batch jobs on high-performance clusters. By reading through clear explanations and structured command examples, you will gain the confidence to interact with cluster schedulers productively. What you'll learn: - Understand foundational HPC architecture, scheduler concepts, and how the PBS queue operates - Craft robust PBS batch scripts with appropriate directive declarations - Submit and monitor jobs using the qsub, qstat, and qdel commands - Configure resource requests including CPU cores, memory limits, and walltime specifications - Manage job dependencies and sequential execution workflows - Troubleshoot failed jobs by analyzing standard output and error logs The course begins with essential terminology and cluster concepts before moving into practical script construction and queue management strategies. You will learn how to optimize your resource requests to minimize queue wait times and ensure successful job completion. This course is designed for researchers, data scientists, and software developers who are new to high-performance computing environments. No prior experience with cluster scheduling is required, though a basic familiarity with the Linux command line is helpful.
