UALink

UALink is a new open standard designed to rival NVIDIA's proprietary NVLink technology. It facilitates high-speed, direct GPU-to-GPU communication crucial for scaling out complex computational tasks across multiple graphics processing units (GPUs) or accelerators within servers or computing pods. The effort emerged from a new consortium spearheaded by AMD, including industry heavyweights such as Intel, Broadcom, Cisco, Google, HPE, Meta, and Microsoft. Notably absent are Arm and NVIDIA.
