AWS ParallelCluster 3.8 is now generally available. Key features in this release are support for Rocky Linux 8 and Amazon EC2 Capacity Blocks for ML, allowing you to reserve highly sought-after GPU instances on a future date to support your short duration machine learning (ML) workloads. Other important features in this release include:

• Scaling strategies to help you meet your scaling and cost requirements, ranging from strict all-or-nothing, that avoid launching idle instances, to best-effort, which prioritizes throughput scaling over avoiding idle instances.
• Support for mounting user-defined file systems in AWS to the /home directory of the head node, helping you simplify cluster storage management.ENnbsp;
• Custom Munge key to help you simplify integration of additional cluster resources that require the Scheduler Munge key.

AWS ParallelCluster is a fully-supported and maintained open-source cluster management tool that enables RENamp;D customers and their IT administrators to operate high-performance computing (HPC) clusters on AWS. AWS ParallelCluster is designed to automatically and securely provision cloud resources into elastically-scaling HPC clusters capable of running scientific, engineering, and machine-learning (ML/AI) workloads at scale on AWS.ENnbsp;

AWS ParallelCluster is available at no additional charge in the AWS Regions listed here, and you pay only for the AWS resources needed to run your applications.
