The following instance types support EFAs:
Differences between EFAs and ENAs
Elastic Network Adapters (ENAs) provide traditional IP networking features that are required to support VPC networking. EFAs provide all of the same traditional IP networking features as ENAs, and they also support OS-bypass capabilities. OS-bypass enables HPC and machine learning applications to bypass the operating system kernel and to communicate directly with the EFA device.
Supported interfaces and libraries
* EFAs support the following interfaces and libraries:
* Open MPI 5 and later
* Open MPI 4.0 or newer is preferred for Graviton
* Intel MPI 2019 Update 5 and later
* NVIDIA Collective Communications Library (NCCL) 2.4.2 and later
