The CXL Consortium, an business requirements physique, devoted to advancing Compute Express Link (CXL) know-how, introduced the discharge of the CXL 3.0 specification right this moment, which will likely be adopted by AMD, Intel, NVIDIA, and different main server gamers.

CXL Consortium launches Compute Express Link 3.0 specification to increase cloth talents and knowledge administration

The CXL 3.0 specification expands on earlier know-how generations to extend scalability and optimize system stage flows with superior switching and cloth capabilities, environment friendly peer-to-peer communications, and fine-grained useful resource sharing throughout a number of compute domains.

Modern datacenters require heterogenous and composable architectures to help compute intensive workloads for purposes akin to Artificial Intelligence and Machine Learning – and we proceed to evolve Compute Express Link  know-how to fulfill business necessities. Developed by our devoted technical workgroup members, the CXL 3.0 specification will allow new utilization fashions in composable disaggregated infrastructure.

  • Siamak Tavallaei, President, CXL Consortium.

CXL is a transformative know-how that continues to construct momentum throughout the business. The introduction of Compute Express Link 3.0 meets the wants of next-generation knowledge facilities with 64 GT/s signaling and a brand new stage of scalability,” stated Travis Karr, normal supervisor of Interconnect SoCs at Rambus. “At Rambus, we’re extraordinarily proud to be members of the rising CXL ecosystem and dedicated to the event of options that may speed up the adoption of this thrilling new know-how.

Key highlights:

  • The Compute Express Link™ 3.0 specification will introduce cloth capabilities and administration, improved reminiscence sharing and pooling, enhanced coherency, and peer-to-peer (P2P) communication.
  • The Compute Express Link 3.0 specification gives two instances the info fee, enhancing knowledge switch to 64 GTs with zero latency over the earlier CXL 2.0. The new specification is at present accessible for public use.
  • CXL Consortium and its partnered firms will convey important insights on Compute Express Link know-how through the Flash Memory Summit (FMS) on August 2nd by means of the 4th.
