AWS Unleashes Hpc8a Instances: A New Era for High-Performance Computing
Amazon Web Services (AWS) has officially launched its Hpc8a instances, the latest addition to its Elastic Compute Cloud (EC2) family. Powered by 5th Generation AMD EPYC processors, these new instances promise a significant leap in performance for compute-intensive workloads. This move underscores the growing demand for specialized cloud infrastructure tailored to the needs of scientific research, financial modeling and advanced engineering.
Performance Gains and Key Specifications
The Hpc8a instances deliver up to 40% higher performance, 42% greater memory bandwidth, and a 25% improvement in price-performance compared to the previous generation Hpc7a instances. The core of this improvement lies in the adoption of the latest AMD EPYC processors, capable of reaching frequencies up to 4.5 GHz.
Currently, the Hpc8a instances are available in a single configuration – the 96xlarge – boasting 192 physical cores, 768 GiB of memory, and up to 300 Gbps of Elastic Fabric Adapter (EFA) networking. This configuration is designed for applications that demand high levels of inter-node communication at scale.
| Instance Name | Physical Cores | Memory (GiB) | EFA Network Bandwidth (Gbps) | Network Bandwidth (Gbps) | Attached Storage |
| Hpc8a.96xlarge | 192 | 768 | Up to 300 | 75 | EBS Only |
The Rise of AMD EPYC in the Cloud
The adoption of 5th Generation AMD EPYC processors in AWS’s Hpc8a instances is part of a broader trend. AMD EPYC chips are gaining traction across major cloud providers, offering a compelling alternative to traditional processors. This increased competition benefits customers through improved performance and pricing.
Optimized for Demanding Workloads
These instances are specifically designed for compute-intensive, tightly coupled HPC workloads. Examples include computational fluid dynamics, simulations for faster design iterations, high-resolution weather modeling, and complex crash simulations. The high core density, memory bandwidth, and low-latency networking are crucial for scaling these applications efficiently and reducing job completion times.
AWS Nitro cards further enhance performance and security by offloading CPU virtualization, storage, and networking functions to dedicated hardware and software. Simultaneous Multithreading (SMT) is disabled on these instances to achieve the best performance for HPC workloads.
Ecosystem Integration and Availability
AWS has streamlined the integration of Hpc8a instances with its existing HPC ecosystem. Users can leverage AWS ParallelCluster and AWS Parallel Computing Service (AWS PCS) to simplify workload submission and cluster creation. Amazon FSx for Lustre provides sub-millisecond latencies and high throughput for storage needs.
Currently, Amazon EC2 Hpc8a instances are available in US East (Ohio) and Europe (Stockholm) AWS Regions. Regional availability and future roadmap information can be found on the AWS Capabilities by Region page.
Pricing and Purchasing Options
Hpc8a instances are available for purchase as On-Demand Instances and through Savings Plans. Detailed pricing information can be found on the Amazon EC2 Pricing page.
