Using Elastic Fabric Adapter (EFA) with AWS PCS

PDFRSS

Elastic Fabric Adapter (EFA) is a high performance advanced networking interconnect from AWS that you can attach to your EC2 instance to accelerate High Performance Computing (HPC) and machine learning applications. Enabling your applications running on an AWS PCS cluster with EFA involves configuring the AWS PCS compute node group instances to use EFA as follows.

Note

Install EFA on an AWS PCS-compatible AMI – The AMI used in the AWS PCS compute node group must have the EFA driver installed and loaded. For information on how to build a custom AMI with EFA software installed, see Custom Amazon Machine Images (AMIs) for AWS PCS.
