Introducing the Compute Express Link™ 2.0 Specification

Compute Express Link™ (CXL™) is an industry supported cache-coherent interconnect for processors, memory expansion and accelerators. CXL supports dynamic multiplexing between a rich set of protocols that includes I/O (CXL.io, based on PCIe®), caching (CXL.cache) and memory (CXL.memory) semantics. CXL.mem allows a host processor to access memory attached to a CXL device. CXL.mem transactions are simple memory load and store transactions that run downstream from the host processor which takes care of all the associated coherency flows. 

This webinar will explore how the CXL.mem protocol can deliver power-efficient performance with emerging applications such as AI, HPC, DL and comms with a coherent interface and low latency. This webinar will also explore type-3 devices and use cases for memory bandwidth expansion, memory capacity expansion and storage class memory.

Compute Express Link™ (CXL™): Memory Challenges and CXL Solutions

CXL technology maintains a unified, coherent memory space between the CPU (host processor) and CXL devices allowing the device to expose its memory as coherent in the platform and allowing the device to directly cache coherent memory. This allows both the CPU and device to share resources for higher performance and reduced software stack complexity. In CXL, the CPU host is primarily responsible for coherency management abstracting peer device caches and CPU caches. The resulting simplified coherence model reduces the device cost, complexity and overhead traditionally associated with coherency across an I/O link. 

Please join Siamak Tavallaei, CXL Consortium Technical Task Force Co-Chair and Principal Architect, Microsoft Azure, Rob Blankenship, Processor Architect and Principal Engineer, Intel, and Kurt Lender, CXL Consortium Marketing Working Group Co-Chair and Senior Ecosystem Enabling Manager, Data Center Group, Intel, for a deep dive into how CXL technology maintains memory coherency between the CPU memory space and memory on attached devices. The webinar will also detail several representative CXL use cases – Caching Devices/Accelerators, Accelerators with Memory, and Memory Buffers.

Introduction to Compute Express Link™ (CXL)

CXL® (Compute Express Link®) enables the addition of a new tier of memory to the memory hierarchy using type-3 devices. There are many first-generation CXL memory expansion devices in the market that will allow this capability. However, due to additional controller and board costs and associated power consumption, much of the value proposition of memory tiering is diluted. 

This webinar will outline a framework to enable CXL devices to be deployed at scale and allow the expansion of platform memory capacity incrementally and cost-effectively. The webinar will also explore how this framework will be a fundamental enabler for more ambitious CXL-enabled memory architectures in the future.
