We’re going to take you into the world of broadcast video, and explain how it led to us announcing today the general availability of EFA on smaller instance sizes. For a range of applications, this is going to save customers a lot of money because they no longer need to use the biggest instances in each instance family to get HPC-style network performance. But the story of how we got there involves our Elastic Fabric Adapter (EFA), some difficult problems presented to us by customers in the entertainment industry, and an invention called the Cloud Digital Interface (CDI). And it started not very far from Hollywood.

We have recently launched three new Amazon EC2 instances types enabled with Elastic Fabric Adapter (EFA), our network interface for Amazon EC2 instances that enables customers to run applications requiring high levels of inter-node communications at scale on AWS. These bring our EFA-enabled count to sixteen different instance families covering a wide range of use cases. EFA is going mainstream and we are just getting started.

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 cloud: that you can run virtually any application, at scale, and right away. Find out more about how Elastic Fabric Adapter (EFA) can help your HPC workloads scale on AWS.

Molecular dynamics (MD) is a simulation method for analyzing the movement and tracing trajectories of atoms and molecules where the dynamics of a system evolve over time. MD simulations are used across various domains such as material sciences, biochemistry, biophysics and are typically used in two broad ways to study a system. The importance of […]
