CXL Fireside Chat


Compute Express Link (CXL) is an open industry standard interconnect offering high-bandwidth, low-latency connectivity between host processors and devices such as accelerators, memory buffers and smart IO adapters. It is designed to address the needs of heterogeneous high performance processing systems, as well as server systems with disaggregated memory and IO resources. In this session, the team will describe the capabilities of CXL, and will also discuss the 2nd generation of CXL (CXL 2.0) with the additional features it will bring to HPC platforms.
