Use of Elastic Fabric Adapter

Question

Why is Elastic Fabric Adapter used? What are the benefits of using EFA over conventional adapter?

Answer 1

Elastic Fabric Adapter is used for the scalability, flexibility, and elasticity of the cloud to use the tightly-coupled HPC applications. With the help of EFA, tightly-coupled HPC applications can have access to the lower and most consistent latency and to those of higher throughput than the traditional TCP channels, which enables it to scale better. EFA also support the dynamically enabled, on-demand on any type of supported EC2 instance without any pre-reservation, giving user the flexibility to respond to the changing business/workload priorities.
