Low-latency HPC interconnect Partial match
Elastic Fabric Adapter maps partly to Cloud RDMA, which uses RDMA over Converged Ethernet v2 (RoCE) VPC networks on HPC series such as H4D and on GPU machines.
- Cloud RDMA uses RoCE v2 network profiles; EFA uses AWS's SRD protocol with libfabric.
- RDMA must be configured when you create the instance; it can't be added to an existing HPC VM.
