AWS Parallel Computing Service Gets Node Lifecycle Actions
AWS just dropped general availability for node lifecycle actions in AWS Parallel Computing Service (PCS), and it's a game-changer for HPC workflows. You can now run custom scripts automatically at specific points in your compute node's lifecycle—think mounting storage, installing software, or setting up monitoring without manual intervention. Define these actions once in your node group config and reuse them across multiple clusters. AWS PCS logs everything for you, so debugging is straightforward. Perfect for anyone scaling HPC workloads on AWS with Slurm.
