AWS ParallelCluster 3.16 is now generally available with a new on-node diagnostics tool, cluster stability improvements, and an updated HPC and AI/ML software stack. pcluster-diag is a diagnostics tool built into the ParallelCluster AMIs that lets you run diagnostic checks on any cluster node with a single command, and get a structured report that makes it easier to identify issues. This release also hardens the cluster lifecycle with more resilient cluster creation, updates, and image builds. The software stack is refreshed, with updated NVIDIA driver, CUDA, EFA installer, and Slurm versions. To get started with pcluster-diag, see Troubleshooting with pcluster-diag. For more details, review the AWS ParallelCluster 3.16.0 release notes.
