Ultra Accelerator Link Consortium (UALink) has announced the expansion of its Board of Directors with the election of Alibaba Cloud Computing Ltd., Apple Inc., and Synopsys Inc. The new Board members will leverage their industry knowledge to advance development and industry adoption of UALink - a high-speed, scale-up interconnect for next-generation AI cluster performance.

"Alibaba Cloud believes that driving AI computing accelerator scale-up interconnection technology by defining core needs and solutions from the perspective of cloud computing and applications has significant value in building the competitiveness of intelligent computing supernodes," said Qiang Liu, VP of Alibaba Cloud, GM of Alibaba Cloud Server Infrastructure. "The UALink consortium, as a leader in the interconnect field of AI accelerators, has brought together key members from the AI infrastructure industry to work together to define interconnect protocol which is natively designed for AI accelerators, driving innovation in AI infrastructure. This will strongly promote the innovation of AI infrastructure and improve the execution efficiency of AI workloads, contributing to the establishment of an open and innovative industry ecosystem."

Synopsys, Inc. today announced the industry's first Ultra Ethernet IP and UALink IP solutions, including controllers, PHYs, and verification IP, to meet the demand for standards-based, high-bandwidth, and low-latency HPC and AI accelerator interconnects. As hyperscale data center infrastructures evolve to support the processing of trillions of parameters in large language models, they must scale to hundreds of thousands of accelerators with highly efficient and fast connections. Synopsys Ultra Ethernet and UALink IP will provide a holistic, low-risk solution for high-speed and low-latency communication to scale-up and scale-out AI architectures.

"For more than 25 years, Synopsys has been at the forefront of providing best-in-class IP solutions that enable designers to accelerate the integration of standards-based functionality," said Neeraj Paliwal, senior vice president of IP product management at Synopsys. "With the industry's first Ultra Ethernet and UALink IP, companies can get a head start on developing a new generation of high-performance chips and systems with broad interoperability to scale future AI and HPC infrastructure."

Ultra Accelerator Link (UALink ) Consortium, led by Board Members from AMD, Amazon Web Services (AWS), Astera Labs, Cisco, Google, Hewlett Packard Enterprise (HPE), Intel, Meta and Microsoft, have announced the incorporation of the Consortium and are extending an invitation for membership to the community. The UALink Promoter Group was founded in May 2024 to define a high-speed, low-latency interconnect for scale-up communications between accelerators and switches in AI pods & clusters. "The UALink standard defines high-speed and low latency communication for scale-up AI systems in data centers"

AMD, Broadcom, Cisco, Google, Hewlett Packard Enterprise (HPE), Intel, Meta and Microsoft today announced they have aligned to develop a new industry standard dedicated to advancing high-speed and low latency communication for scale-up AI systems linking in Data Centers.

Called the Ultra Accelerator Link (UALink), this initial group will define and establish an open industry standard that will enable AI accelerators to communicate more effectively. By creating an interconnect based upon open standards, UALink will enable system OEMs, IT professionals and system integrators to create a pathway for easier integration, greater flexibility and scalability of their AI-connected data centers.
