OpenCAPI Consortium Merges Into CXL

The {industry} has been present process vital adjustments in computing. Utility particular {hardware} acceleration is changing into commonplace and new reminiscence applied sciences are influencing the economics of computing. To deal with the necessity for an open structure to permit full {industry} participation, the OpenCAPI Consortium (OCC) was based in 2016. The structure that was outlined allowed any microprocessor to connect to coherent user-level accelerators, superior reminiscences, and was agnostic to the processor structure. In 2021, OCC introduced the Open Reminiscence Interface (OMI). Primarily based on OpenCAPI, OMI is a serial connected close to reminiscence interface that gives low latency and excessive bandwidth connections for most important reminiscence.

In 2019, the Compute Categorical Hyperlink (CXL) Consortium was launched to ship an industry-supported cache-coherent interconnect for processors, reminiscence enlargement, and accelerators. In 2020, the CXL and Gen-Z Consortiums introduced plans to implement interoperability between their respective applied sciences, and in early 2022, Gen-Z transferred its specs and property to the CXL Consortium.

Persevering with this spirit, we announce that OCC and CXL are coming into an settlement, which if authorized and agreed upon by all events, would switch the OpenCAPI and OMI specs and OpenCAPI Consortium property to the CXL Consortium.

“We’re happy to see the {industry} coming collectively round one group driving open innovation and leveraging the worth OpenCAPI and Open Reminiscence Interface present for coherent interconnects and low latency, close to reminiscence interfaces. We count on this can yield the most effective enterprise outcomes for the {industry} as a complete and for the members of the consortia.” – Bob Szabo, OpenCAPI Consortium President

“We’re enthusiastic about this chance to focus the {industry} on specs residing beneath one group transferring ahead. That is the correct time for our mutual members to work collectively to advance a standard-high-speed coherent interconnect/material for the good thing about the {industry} . Task of OCC property will permit for CXL Consortium to freely make the most of what OCC has already developed with OpenCAPI/OMI.” – Siamak Tavallaei, CXL Consortium President

About OpenCAPI Consortium
The OpenCAPI Consortium is a not-for-profit group fashioned in 2016 and is an open discussion board to handle the OpenCAPI specs. OpenCAPI is an open coherent high-performance bus interface. To be taught extra concerning the OpenCAPI Consortium, go to
