What Does CXL Mean? | Checksum Episode 23

Compute Express Link (CXL) is an industry-supported cache-coherent interconnect for processors, memory expansion and accelerators. But what does this really mean? In this special Gestalt IT Checksum, recorded live at the CXL Forum in New York City on October 12, 2022, Stephen Foskett explains the reality of CXL. Beyond right-sizing memory, CXL allows the creation of more-flexible servers, rack-scale architecture, and true composability. But there are many potential challenges to this roadmap, and CXL will need standards and end-user buy-in, not just hardware and software.
