CXL

Compute Express Link

A high-speed interconnect technology that provides a standardized, high-bandwidth, low-latency interface for communication between processors and accelerators in data centers and high-performance computing environments.

CXL enables efficient and scalable communication between the central processing unit (CPU) and accelerators, such as graphics processing units (GPUs), field-programmable gate arrays (FPGAs), and other specialized processing elements. This allows for more efficient use of the available processing resources and enables applications to take advantage of the specialized processing capabilities of accelerators.

CXL is designed to be a standardized and open technology, allowing for interoperability between different hardware vendors. This allows data center administrators and users to take advantage of the best available processing resources, regardless of the vendor, and to leverage a common set of software tools and development environments. By standardizing the interface between processors and accelerators, CXL helps to simplify the development and deployment of high-performance computing systems and enables the creation of more efficient and scalable data center infrastructures.
