Tear Down These Walls: How CXL Could Reinvent the Data Center

The move to heterogenous computing will require shifting some … interconnects to a more performant industry standard interface enabling new capabilities like memory tiers, pooled memory, and even the convergence of memory and storage. And to unshackle architectural innovation and choice, we need an open standard with broad industry acceptance. Enter the Compute Express Link (CXL). CXL is an open interface that standardizes a high-performance interconnect for data-centric platforms – it provides the ability to connect CPUs to XPUs, storage, memory and networking, enabling increased degrees of freedom for platform architecture via the ability to build more optimized infrastructures.

Ayar Labs Demos Terabit Optical Link for Co-Packaged Optics and Chip-to-Chip Connectivity

SANTA CLARA, Calif. — Ayar Labs announced today that it has successfully demonstrated what is said is the industry’s first terabit per second Wavelength Division Multiplexing (WDM) optical link with its TeraPHY optical I/O chiplet and SuperNova multi-wavelength optical source. The demonstration shows a fully functional TeraPHY chiplet with 8 optical ports running error free […]

Arm Releases Details on 2 Neoverse Platforms and Mesh Interconnect for HPC, ML

Arm Holdings this morning released information on two new compute platforms and an interconnect for HPC, machine learning and other workloads introduced last September: The Arm Neoverse V1 platform is a new computing tier for Arm and the first Arm-designed core to support Scalable Vector Extension (SVE), delivering 50 percent more performance for HPC and […]

2020 Predictions from Radio Free HPC

In this podcast, the Radio Free HPC team lays out their tech predictions for 2020. “Henry predicts that we’ll see a RISC-V based supercomputer on the TOP500 list by the end of 2020 – gutsy call on that. This is a double down on a bet that Dan and Henry have, so he’s reinforcing his position. Dan also sees 2020 as the “Year of the FPGA.”

GigaIO Steps Up with PCIe Gen 4 Interconnect for HPC

In this video from ISC 2019, Marc Lehrer from GigaIO describes the company’s innovative HPC interconnect technology based on PCIe Gen 4. “For your most demanding workloads, you want time to solution. The GigaIO hyper-performance network breaks the constraints of old architectures, opening up new configuration possibilities that radically reduces system cost and protect your investment by enabling you to easily adopt new compute or business processes.”

Gen-Z Consortium Announces the Public Release of Its Core Specification 1.0

Today the Gen-Z Consortium released the Gen-Z Core Specification 1.0 on its website. As an open systems interconnect, Gen-Z is designed to provide memory semantic access to data and devices via direct-attached, switched or fabric topologies. “The release of core specification 1.0 today is a significant step towards realization of new architectures and evolution of existing technologies to expand into new roles. Samsung is excited to be a member of the Gen-Z Consortium and is committed towards industry open standards.”

Video: Slim Fly – A Cost Effective Low-Diameter Network Topology

“We introduce a high-performance cost-effective network topology called Slim Fly that approaches the theoretically optimal network diameter. Slim Fly is based on graphs that approximate the solution to the degree-diameter problem. We analyze Slim Fly and compare it to both traditional and state-of-the-art networks. Our analysis shows that Slim Fly has significant advantages over other topologies in latency, bandwidth, resiliency, cost, and power consumption.”
