Announcing Amazon EC2 Hpc7a instances

AWS announces the general availability of Amazon Elastic Compute Cloud (Amazon EC2) Hpc7a instances. Amazon Elastic Compute Cloud Hpc7a instances, powered by 4th generation AMD EPYC processors, deliver up to 2.5x better performance compared to Amazon EC2 Hpc6a instances. Hpc7a instances feature 2x higher core density (up to 192 cores), 2.1x higher memory bandwidth throughput, 2x memory (768 GB), and 3x higher network bandwidth compared to Hpc6a instances. Hpc7a instances offer 300 Gbps of Elastic Fabric Adapter (EFA) network bandwidth for fast and low-latency internode communications. These instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor. The Nitro System delivers practically all the compute and memory resources of the host hardware to your instances. Hpc7a instances feature Double Data Rate 5 (DDR5) memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory. Hpc7a instances are ideal for compute-intensive, latency-sensitive high performance computing (HPC) workloads, helping you scale more efficiently on fewer nodes when compared to Hpc6a instances. Hpc7a instances are designed to run your tightly coupled HPC workloads—such as computational fluid dynamics (CFD), weather forecasting, and multiphysics simulations—with better performance. Hpc7a instances are available in four sizes, with 24, 48, 96, and 192 vCPUs, in the following [AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/): US East (Ohio), Europe (Ireland), and AWS GovCloud (US-West). To optimize Hpc7a instances networking for tightly coupled workloads, you can access Hpc7a instances in a single Availability Zone within a Region.
