AWS PCS Supports EC2 Capacity Blocks for ML Workloads
🔧 Amazon Web Services has added native support for EC2 Capacity Blocks in the Parallel Computing Service (PCS), enabling use of reserved EC2 instances directly within PCS Slurm clusters. This integration lets Capacity Blocks be associated with PCS compute node groups via an EC2 Launch Template, simplifying capacity planning for GPU‑based ML workloads. The feature is available in all Regions where both services are offered and aims to improve availability and predictability for cutting‑edge GPU jobs.
