Keynote 1: Compute Express Link (CXL) changing the game for Cloud Computing

Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. High-performance workloads demand heterogeneous processing, tiered memory architecture, persistent memory support, infrastructure accelerators such as smart NICs, and infrastructure processing units to meet the demands of the emerging compute landscape. Applications such as Artificial Intelligence, Machine Learning, Analytics, 5G, automotive, and high-performance computing are driving significant change in infrastructure such as Cloud, Edge, and client computing. Interconnect is a key pillar in this evolving computational landscape. The recent advent of Compute Express Link (CXL), a new open standard for cache-coherent interconnect, with its memory and coherency semantics has made it possible to pool computational and memory resources at the rack level using low-latency, higher-throughput, and memorycoherent access mechanisms. CXL is adopting networking features such as multi-host connectivity, pooled memory, persistence flows, and fabric manager while keeping its low-latency load-store semantics intact. The load-store I/O interconnects such as PCI Express (PCIe) and CXL are evolving to provide efficient access mechanisms across multiple nodes with advanced atomics, acceleration, smart NICs, persistent memory support etc. In this talk we will explore how synergistic evolution across load-store interconnects and fabrics can benefit the compute infrastructure of the future.
