Introducing CXL 3.0: Expanded Capabilities for Increased Scale and Optimized Resource Utilization

Time: Wed Sep 14 | 4:35pm - 5:25pm


Compute Express Link™ (CXL™) is an open industry-standard interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between the host processor and devices such as accelerators, memory buffers, and smart I/O devices. CXL technology is designed to address the growing needs of high-performance computational workloads by supporting heterogeneous processing and memory systems for applications in Artificial Intelligence, Machine Learning, communication systems, and High-Performance Computing. In this presentation, attendees will learn about the next generation of CXL technology. The CXL 3.0 specification, releasing in Q3 2022, adds support for double the bandwidth and improved capability for better scalability and improved resource utilization. CXL 3.0 features include enhanced memory pooling and new memory usage models, multi-level switching with multiple hosts, fabric capabilities and enhanced fabric management, new symmetric coherency capabilities, and improved software capabilities.
