Amazon EC2 Hpc7a Instances

HPC-optimized instances powered by 4th Gen AMD EPYC processors

Amazon Elastic Compute Cloud (Amazon EC2) Hpc7a instances, powered by 4th Gen 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. These instances offer 300 Gbps of Elastic Fabric Adapter (EFA) network bandwidth, powered by the AWS Nitro System, for fast and low-latency internode communications. 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. These instances are ideal for compute-intensive, latency-sensitive 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.

Fast results

With 300 Gbps EFA networking, you have access to a high-throughput, low-latency, low-jitter channel for tightly coupled workloads. EFA networking allows you to scale faster and reduce time-to-insight for your HPC workloads.

Operational flexibility and efficiency

Instance size options help you manage costs for your workloads that are licensed on a per-core basis. Right-size your workload resources by choosing the ideal cores per node while continuing to harness available memory and network bandwidth, regardless of the instance size that you select. Additionally, with AWS ParallelCluster, you can provision Hpc7a instances alongside other instance types within the same cluster. This gives you the flexibility to run different workloads optimized for different instances within your cluster.

Maximized resource efficiency

Hpc7a instances benefit from the Nitro System, a collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software. The Nitro System is used to deliver high performance, high availability, and increased security.


High performance compute, networking, and storage

Hpc7a instances are powered by up to 192 cores of 4th Gen AMD EPYC processors with 768 GiB total memory (up to 8 GiB of memory per core) for the most demanding HPC workloads. It uses the latest-generation Nitro Cards and EFA, which deliver 300 Gbps of network throughput to interconnected nodes. EFA is designed to help applications get the lowest latency and highest throughput from the AWS network. You can also use Amazon FSx for Lustre for sub-millisecond latencies and up to hundreds of gigabytes per second of throughput for storage. 

Instance sizing options and cluster management

Hpc7a instances offer 24-, 48-, 96-, and 192-core 4th Gen AMD EPYC processors. The larger 192-core size delivers greater efficiency when compared to Hpc6a instances powered by 3rd Gen AMD EPYC processors, while the ability to choose among multiple sizes helps you optimize cores per node for your specific workload. Additionally, ParallelCluster uses a simple graphical user interface (GUI) or text file to model and provision the resources needed for your HPC applications in an automated and secure manner.

Built on the Nitro System

The Nitro System can be assembled in multiple ways, giving AWS the flexibility to design and rapidly deliver EC2 instance types with an ever-broadening selection of compute, storage, memory, and networking options. Nitro Cards offload and accelerate I/O for functions, ultimately increasing overall system performance.

"AWS is used in various divisions and competencies across the entire University of Michigan Solar Car team to accelerate and improve our simulation, analysis, and software development. We’ve been able to run 1,000 CFD simulations and increase our vehicle’s performance by 20% in the span of two months thanks to fast turnaround on high-fidelity simulations. The release of Amazon EC2 Hpc7a instances will help us to further experiment with ways to increase the number of CFD simulations we can run to accelerate our designs."

Thomas Capderou, Aerodynamics Division Lead, University of Michigan Solar Car Team

"Using AWS across the entire University of Michigan Solar Car team has helped us improve our processes associated with the simulation, analysis, and development projects we can run. Transitioning our team’s software and in-house simulation infrastructure to AWS has had a significant impact on our iteration speed and expanded the scope of several ongoing projects. The launch of Amazon EC2 Hpc7a instances will help us to investigate ways to further expand project scope and 300 Gbps interconnect using EFA introduces the potential for us to iterate our designs even faster."
