AWS Parallel Computing Service (PCS) now supports custom Generic Resource (GRES) settings, hardware topology, and NVIDIA Multi-Instance GPU (MIG). These enhancements, coupled with Slurm version 26.05, provide finer control over how Slurm schedules cluster hardware. This improves task placement for high-performance computing (HPC) and machine learning workloads, allowing for optimized rank placement and GPU resource partitioning. These capabilities are generally available in all AWS Regions where PCS operates.
