Enabling New Server Architectures With The CXL Interconnect
By Lou Ternullo - 09 Mar, 2023 - Comments: 0

The ever-growing demand for higher performance compute is motivating the exploration of new compute offload architectures for the data center. Artificial intelligence and machine learning (AI/ML) are just one example of the increasingly complex and demanding workloads that are pushing data centers to move away from the classic server computing architecture. These more demanding workloads can be... » read more

CXL Picks Up Steam In Data Centers
By Marie C. Baca - 26 Jan, 2023 - Comments: 0

CXL is gaining traction inside large data centers as a way of boosting utilization of different compute elements, such as memories and accelerators, while minimizing the need for additional racks of servers. But the standard is being extended and modified so quickly that it is difficult to keep up with all the changes, each of which needs to be verified and validated across a growing swath of h... » read more

CXL 3.0: From Expansion To Scaling
By Danny Moore - 06 Oct, 2022 - Comments: 0

At the Flash Memory Summit in August, the CXL Consortium released the latest, and highly anticipated, version 3.0 of the Compute Express Link (CXL) specification. This new version of the specification builds on previous generations and introduces several compelling new features that promise to increase data center performance and scalability, while reducing the total cost of ownership (TCO). ... » read more

Compute Express Link (CXL): All You Need To Know
By Rambus - 10 Aug, 2022 - Comments: 0

An in-depth look at Compute Express Link  (CXL) 2.0, an open standard cache-coherent interconnect between processors and accelerators, smart NICs, and memory devices. We explore how CXL is helping data centers more efficiently handle the yottabytes of data generated by artificial intelligence (AI) and machine learning (ML) applications. We discuss how CXL technology maintains memory c... » read more

Choosing The Right Server Interface Architectures For High Performance Computing
By Jerry Lotto - 12 Apr, 2022 - Comments: 0

The largest bulk and cost of a modern high-performance computing (HPC) installation involves the acquisition or provisioning of many identical systems, interconnected by one or more networks, typically Ethernet and/or InfiniBand. Most HPC experts know that there are many choices between different server manufacturers and the options of form factor, CPU, RAM configuration, out of band management... » read more
