Amazon EC2 Hpc7g Instances

HPC-optimized instances powered by AWS Graviton3E processors 

Amazon Elastic Compute Cloud (Amazon EC2) Hpc7g instances enable the best price performance for high performance computing (HPC) workloads on AWS. They offer up to 70% better performance and almost 3x better price performance compared to previous-generation AWS Graviton-based instances for compute-intensive HPC workloads. Hpc7g instances are powered by AWS Graviton 3E processors and provide up to 35% higher vector instruction performance compared to existing AWS Graviton3 instances.

These instances provide up to 2x better floating-point performance compared to instances powered by AWS Graviton2 processors. Hpc7g instances are built on the AWS Nitro System and provide 200 Gbps network bandwidth for low-latency internode communication for tightly coupled workloads that require highly parallelized, clustered compute resources.

You can scale your HPC clusters on Hpc7g instances to run compute-intensive workloads such as computational fluid dynamics (CFD), weather forecasting, and molecular dynamics. With these instances, you can carry out complex calculations across HPC clusters using up to tens of thousands of cores with high performance and lower costs.

High performance

Hpc7g instances are purpose-built to offer performance for tightly coupled HPC workloads and reduce queue time and execution time across your HPC cluster. Graviton3E processors, with up to 35% higher vector instruction processing performance than Graviton3 processors, make it easier for you to get the most from running your HPC workloads on AWS to solve complex scientific, academic, and business problems. Hpc7g instances include up to 64 cores of Arm-based Graviton3E processors with 128 GiB of memory.

Cost efficiency at massive scale

Hpc7g instances are designed for cost efficiency, even as you scale HPC clusters up to tens of thousands of cores. Elastic Fabric Adapter (EFA) provides 200 Gbps interconnect speeds for low latency and high throughput, enabling workloads such as CFD, molecular dynamics, and numerical weather analysis to scale out nearly endlessly. 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.

Maximized resource efficiency

Hpc7g 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.


Powered by high-performing Graviton3E processors

Hpc7g instances are powered by Arm-based Graviton3E processors, which feature 35% higher floating-point performance compared to Graviton3-based instances. Graviton3E delivers up to 2x performance as measured by the LINPACK benchmark, and 20% higher performance as measured by Life Science applications such as GROMACS. Hpc7g instances are available in single Availability Zones, enabling workloads to achieve the low-latency network performance necessary for tightly coupled node-to-node communication for HPC applications.


Highly scalable with optimizable cores per node

Hpc7g instances deliver 2x more EFA bandwidth compared to Graviton2 compute-optimized instances. Scalable Vector Extension (SVE) provides hardware acceleration for HPC codes solving variable-length vector math. SVE helps tightly coupled compute-intensive HPC workloads perform better and scale-out larger. Hpc7g instances are offered in multiple instance sizes designed to optimize cores per node for your specific workload. Hpc7g instances offer 16-, 32-, and 64-core Graviton3E processors with 128 GiB total memory and 8 GB/core, 4 GB/core, and 2 GB/core options, respectively.

Built on the Nitro System

The Nitro System can be assembled in different 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.
