In January 2022, we launched Amazon EC2 Hpc6a situations for purchasers to effectively run their compute-bound excessive efficiency computing (HPC) workloads on AWS with as much as 65 % higher worth efficiency over comparable x86-based compute-optimized situations.
As their jobs develop extra complicated, clients have requested for extra cores with extra compute efficiency and extra reminiscence and community efficiency to scale back the time to finish jobs. Moreover, as clients look to carry extra of their HPC workloads to EC2, they’ve requested how we are able to make it simpler to distribute processes to make one of the best use of reminiscence and community bandwidth, to align with their workload necessities.
At the moment, we’re saying the final availability of Amazon EC2 Hpc7a situations, the following era of occasion varieties which might be purpose-built for tightly coupled HPC workloads. Hpc7a situations powered by the 4th Gen AMD EPYC processors (Genoa) ship as much as 2.5 occasions higher efficiency in comparison with Hpc6a situations. These situations supply 300 Gbps Elastic Cloth Adapter (EFA) bandwidth powered by the AWS Nitro System, for quick and low-latency internode communications.
Hpc7a situations characteristic Double Knowledge Charge 5 (DDR5) reminiscence, which offers 50 % larger reminiscence bandwidth in comparison with DDR4 reminiscence to allow high-speed entry to information in reminiscence. These situations are perfect for compute-intensive, latency-sensitive workloads resembling computational fluid dynamics (CFD) and numerical climate prediction (NWP).
In case you are operating on Hpc6a, you should use Hpc7a situations and reap the benefits of the two occasions larger core density, 2.1 occasions larger efficient reminiscence bandwidth, and three occasions larger community bandwidth to decrease the time wanted to finish jobs in comparison with Hpc6a situations.
Right here’s a fast infographic that reveals you ways the Hpc7a situations and the 4th Gen AMD EPYC processor (Genoa) evaluate to the earlier situations and processor:
Hpc7a situations characteristic sizes of as much as 192 cores of the AMD EPYC processors CPUs with 768 GiB RAM. Listed here are the detailed specs:
| Occasion Identify | CPUs | RAM (Gib) |
EFA Community Bandwidth (Gbps) |
Hooked up Storage |
| Hpc7a.12xlarge | 24 | 768 | As much as 300 | EBS Solely |
| Hpc7a.24xlarge | 48 | 768 | As much as 300 | EBS Solely |
| Hpc7a.48xlarge | 96 | 768 | As much as 300 | EBS Solely |
| Hpc7a.96xlarge | 192 | 768 | As much as 300 | EBS Solely |
These situations present larger compute, reminiscence, and community efficiency to run essentially the most compute-intensive workloads, resembling CFD, climate forecasting, molecular dynamics, and computational chemistry on AWS.
Just like EC2 Hpc7g situations launched a month earlier, we’re providing smaller occasion sizes that makes it simpler for purchasers to select a smaller variety of CPU cores to activate whereas protecting all different assets fixed based mostly on their workload necessities. For HPC workloads, widespread situations embrace offering extra reminiscence bandwidth per core for CFD workloads, allocating fewer cores in license-bound situations, and supporting extra reminiscence per core. To be taught extra, see Occasion sizes within the Amazon EC2 Hpc7 household – a distinct expertise within the AWS HPC Weblog.
As with Hpc6a situations, you should use the Hpc7a occasion to run your largest and most complicated HPC simulations on EC2 and optimize for value and efficiency. You may also use the brand new Hpc7a situations with AWS Batch and AWS ParallelCluster to simplify workload submission and cluster creation. You may also use Amazon FSx for Lustre for submillisecond latencies and as much as a whole bunch of gigabytes per second of throughput for storage.
To realize one of the best efficiency for HPC workloads, these situations have Simultaneous Multithreading (SMT) disabled, they’re accessible in a single Availability Zone, they usually have restricted exterior community and EBS bandwidth.
Now Accessible
Amazon EC2 Hpc7a situations can be found as we speak in three AWS Areas: US East (Ohio), EU (Eire), and US GovCloud for buy in On-Demand, Reserved Situations, and Financial savings Plans. For extra info, see the Amazon EC2 pricing web page.
