AWS Parallel Computing Service (PCS) now supports Amazon EC2 Capacity Blocks for ML

AWS Parallel Computing Service (PCS) now supports Amazon EC2 Capacity Blocks for ML. You can now use Amazon EC2 instances reserved using EC2 Capacity Blocks natively in PCS clusters.

Native support for EC2 Capacity Blocks in PCS simplifies capacity planning for cutting-edge GPU-based workloads in Slurm clusters, helping to ensure that GPU capacity is available when and where it’s needed. EC2 Capacity Blocks can be associated with PCS compute node groups via an EC2 Launch Template.

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, elastic environments that integrate compute, storage, networking, and visualization tools. 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.

PCS now supports EC2 Capacity Blocks in all AWS Regions where both services are available. Read more about PCS support for EC2 Capacity Blocks in the PCS User Guide.
