Aws efa. An Elastic Fabric Adapter (EFA) is a network device that you can attach to your Amazon EC2 instance to accelerate High Performance Computing (HPC) and machine learning applications. Low Latency Network Elastic Fabric Adapter (EFA) is a network interface for Amazon EC2 instances that enables customers to run applications requiring high levels of inter-node communications at scale on AWS. Elastic Fabric Adapter (EFA) is a network interface for Amazon EC2 instances that enables customers to run applications requiring high levels of inter-node communications at scale on AWS. EFA is a network device that accelerates AI/ML and HPC applications on Amazon EC2 instances. Elastic Fabric Adapter (EFA) is a network device that you can attach to your Amazon EC2 instances to accelerate Artificial Intelligence (AI), Machine learning (ML), and High Performance Computing (HPC) workloads. However, unlike elastic network interfaces, EFAs can't be attached to or detached from an instance in a running state. Learn how to create, attach, and monitor EFA devices, and see the supported interfaces, libraries, and instance types. . Learn how to launch an EFA and MPI-enabled cluster for HPC workloads on Amazon EC2 You can create an EFA and attach it to an Amazon EC2 instance much like any other elastic network interface in Amazon EC2. jlofeojjrzjvbwlnfwmuknurbsujbyckiewuxexkbgtgbwrrsnmt
