What is Omni-path architecture?

Omni-Path (also Omni-Path Architecture, abbr. OPA) was a high-performance communication architecture owned by Intel. It aims for low communication latency, low power consumption and a high throughput. Intel planned to develop technology based on this architecture for exascale computing.

What is Omni-path switch?

Intel® Omni-Path Architecture is designed to support high message rate traffic from each node through the fabric. With ever-increasing processing power and core counts in Intel® Xeon® processors and Intel® Xeon Phi™ processors, that means the fabric has to support high bandwidth as well as high message rate throughput.

What is OPA in networking?

The Open Policy Agent (OPA, pronounced “oh-pa”) is an open source, general-purpose policy engine that unifies policy enforcement across the stack. OPA provides a high-level declarative language that lets you specify policy as code and simple APIs to offload policy decision-making from your software.

How is InfiniBand different from Ethernet?

Higher performance, higher radix and low-latency solutions: Today, Ethernet switches offer connectivity of up to 400 Gbps. In contrast, InfiniBand HDR only offers connectivity of up to 200 Gbps and Fibre channel offers connectivity of up to 32 Gbps.

Who is the owner of the Omni Path Architecture?

Jump to navigation Jump to search. Omni-Path (also Omni-Path Architecture, abbr. OPA) is a high-performance communication architecture owned by Intel. It aims for low communication latency, low power consumption and a high throughput.

When did InfiniBand implement the Omni-Path fabric?

In April 2016, implementation of the InfiniBand “verbs” interface for the Omni-Path fabric was discussed.

What are the features of Intel Omni Path Architecture?

Intel® Omni-Path Architecture (Intel® OPA) has been designed to meet the requirements of clusters from small to large scale. This includes ground-breaking quality of service (QoS) features meant to keep latency low, bandwidth high, and message rate high, even at scale.

What’s the difference between Intel OPA and InfiniBand?

To improve on the InfiniBand specification and design, Intel is using the industry’s best technologies including those acquired from QLogic and Cray alongside Intel® technologies. While both Intel® OPA and InfiniBand* Enhanced Data Rate (EDR) will run at 100Gbps, there are many differences.
