Aws Efa Vs Infiniband. Elastic Fabric Adapter (EFA) 是一種用於加速高效能

Elastic Fabric Adapter (EFA) 是一種用於加速高效能運算 (HPC) 應用程式的裝置。 如果符合以下條件， AWS Batch 支援使用 EFA 的應用程式。 如需支援 EFA 的執行個體類型清單，請參閱 Amazon EC2 使用者指南 中支 援的執行個體類型。. EFA: 弹性织物适配器 HCA: 主机通道适配器 IB: Infiniband MFU: 模型浮点运算利用率（例如，在A100上半精度时 mfu=0. The presentation covered an overview of high performance computing on AWS, a deep dive on what EFA is and how it works, and the road ahead for further developing EFA. It has similar goals (low latency via kernel bypass), but is implemented using AWS Nitro NICs and regular Ethernet networking. EFA still lags behind other networking options on performance: NVIDIA's InfiniBand and Spectrum-X, as well as RoCEv2 options from Cisco, Arista, and Juniper. AWS’s compute infrastructure is very much not like a ‘normal’ supercomputer (whatever that is). Performance Metrics: InfiniBand vs Ethernet InfiniBand: Leading in Low Latency and High Throughput We would like to show you a description here but the site won’t allow us. 오늘은 첫 번째로 고속 네트워크 인터페이스인 Elastic Fabric Adapter에 대해 The EFA available on instances of AWS’s p4d. On P4d instances, the container has access to 4 EFA devices. This document summarizes a presentation about Amazon's Elastic Fabric Adapter (EFA).
