In January 2022, we launched Amazon EC2 Hpc6a cases for patrons to effectively run their compute-bound excessive efficiency computing (HPC) workloads on AWS with as much as 65 p.c higher value efficiency over comparable x86-based compute-optimized cases.
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 the perfect use of reminiscence and community bandwidth, to align with their workload necessities.
In the present day, we’re saying the overall availability of Amazon EC2 Hpc7a cases, the subsequent technology of occasion varieties which can be purpose-built for tightly coupled HPC workloads. Hpc7a cases powered by the 4th Gen AMD EPYC processors (Genoa) ship as much as 2.5 instances higher efficiency in comparison with Hpc6a cases. These cases provide 300 Gbps Elastic Material Adapter (EFA) bandwidth powered by the AWS Nitro System, for quick and low-latency internode communications.
Hpc7a cases function Double Information Charge 5 (DDR5) reminiscence, which offers 50 p.c larger reminiscence bandwidth in comparison with DDR4 reminiscence to allow high-speed entry to knowledge in reminiscence. These cases are perfect for compute-intensive, latency-sensitive workloads equivalent to computational fluid dynamics (CFD) and numerical weather prediction (NWP).
In case you are operating on Hpc6a, you should use Hpc7a cases and make the most of the two instances larger core density, 2.1 instances larger efficient reminiscence bandwidth, and three instances larger community bandwidth to decrease the time wanted to finish jobs in comparison with Hpc6a cases.
Right here’s a fast infographic that reveals you ways the Hpc7a cases and the 4th Gen AMD EPYC processor (Genoa) examine to the earlier cases and processor:
Hpc7a cases function 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 cases present larger compute, reminiscence, and community efficiency to run essentially the most compute-intensive workloads, equivalent to CFD, climate forecasting, molecular dynamics, and computational chemistry on AWS.
Just like EC2 Hpc7g cases launched a month earlier, we’re providing smaller occasion sizes that makes it simpler for patrons to select a smaller variety of CPU cores to activate whereas preserving all different assets fixed based mostly on their workload necessities. For HPC workloads, frequent eventualities embrace offering extra reminiscence bandwidth per core for CFD workloads, allocating fewer cores in license-bound eventualities, and supporting extra reminiscence per core. To study extra, see Occasion sizes within the Amazon EC2 Hpc7 household – a special expertise within the AWS HPC Weblog.
As with Hpc6a cases, 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 as well use the brand new Hpc7a cases with AWS Batch and AWS ParallelCluster to simplify workload submission and cluster creation. You may as well use Amazon FSx for Lustre for submillisecond latencies and as much as tons of of gigabytes per second of throughput for storage.
To attain the perfect efficiency for HPC workloads, these cases have Simultaneous Multithreading (SMT) disabled, they’re obtainable in a single Availability Zone, they usually have restricted exterior community and EBS bandwidth.
Amazon EC2 Hpc7a cases can be found at present in three AWS Areas: US East (Ohio), EU (Eire), and US GovCloud for buy in On-Demand, Reserved Cases, and Financial savings Plans. For extra data, see the Amazon EC2 pricing web page.
