Aside

For each project we establish relationships with partners who we know will help us create added value for your project. As well as bringing together the public and private sectors.

As well as bringing together the public and private sectors. We announced Elastic Fabric Adapter (EFA) at re:Invent 2018 and made it available in preview form at the time. During the preview, AWS customers put EFA through its paces on a variety of tightly-coupled HPC workloads, providing us with valuable feedback and helping us to fine-tune the final product.

Now Available Today I am happy to announce that EFA is now ready for production use in multiple AWS regions. It is ready to support demanding HPC workloads that need lower and more consistent network latency, along with higher throughput, than is possible with traditional TCP communication.

This launch lets you apply the scale, flexibility, and elasticity of the AWS Cloud to tightly-coupled HPC apps and I can’t wait to hear what you do with it. You can, for example, scale up to thousands of compute nodes without having to reserve the hardware or the network ahead of time

All About EFA
An Elastic Fabric Adapter is an AWS Elastic Network Adapter with added capabilities . An EFA can still handle IP traffic, but also supports an important access model commonly called OS bypass. This model allows the application access the network interface without having to get the operating system involved with each message. Doing so reduces overhead and allows the application to run more efficiently.
