AWS Parallel Computing Service (PCS) now supports Slurm CLI Filter plugins

AWS Parallel Computing Service (PCS) now supports Slurm CLI Filter plugins, enabling you to extend and modify how Slurm schedules and processes your high performance computing (HPC) workloads without modifying Slurm directly.

Using CLI Filter plugins, you can now define custom policies for job submission to your clusters. For example, you can define policies that verify certain flags or fields of jobs when users submit them, automatically reject jobs submitted without specific attributes, or even modify job parameters.

PCS is a managed service that makes it easier for you to run and scale your high performance computing (HPC) workloads and build scientific and engineering models on AWS using Slurm. You can use PCS to build complete environments that integrate compute, storage, networking, and visualization. PCS simplifies cluster operations with managed updates and built-in observability features, helping to remove the burden of maintenance. You can work in a familiar environment, focusing on your research and innovation instead of worrying about infrastructure.

This feature is now available in all AWS Regions where PCS is available. To learn more about using Slurm CLI Filter plugins with PCS, see the PCS User Guide.
