Deliver high-performance, robust PCIe link connectivity with optimized thermal efficiency in Universal Baseboard (UBB) designs
UBB Specification Background: As AI models grow in complexity, the demand for larger scale AI systems with distributed processing across multiple GPUs intensifies. To meet this challenge, the Open Compute Project (OCP) community introduced a modular UBB to enable flexible and scalable GPU system configurations while addressing the need for efficient heat dissipation.
