In recent years, we’ve all been amazed at how large areas of scientific computing have moved to abstract their workflows away from the details of systems and cluster architecture. Bioinformatics has really lead the way in this regard - …

AWS worked backwards from an essential problem in HPC networking (MPI ranks need to exchange lots of data quickly) and found a different solution for our unique circumstances, without trading off the things customers love the most about …

Containers are rapidly maturing within the high performance computing (HPC) community and we’re excited to be part of the movement: listening to what customers have to say and feeding this back to both the community and our own product and …

Arm and AWS are jointly sponsoring a summer hackathon that’s being run by the Arm HPC User group (A-HUG - and definitely we send a hug to everyone out there). The goal of the hackathon is to get loads of codes with Spack recipes …

Some workloads generate a LOT of output files and sometimes quite suddenly. For codes like OpenFOAM, this is data that you may not need until later when you run a post-processing job. Given the amount of data isn’t always predictable, there …

In the search for HPC application performance, there’s more than one way to build a network. HPC applications (or “codes” as we usually call them) are often at the mercy of the network underpinning an HPC cluster. If your CPUs aren’t busy, …

In this blog post, we will explain how to launch highly available HPC clusters across an AWS Region. The solution is deployed using the AWS Cloud Developer Kit (AWS CDK), a software development framework for defining cloud infrastructure in …

By popular request, we’re looking today at the EFA software stack and environment: how to make sure it’s set up correctly (so you get great performance from your codes), how to tell if it’s not, and how to fix that. Austin Cherian, our …
