Boston Linux & UNIX was originally founded in 1994 as part of The Boston Computer Society. We meet on the third Wednesday of each month at the Massachusetts Institute of Technology, in Building E51.

Short Takes: CXL in High Performance Computing; SCC Redux; and the UCIe Standard for Chip Design

New developments in HPC and Chip Design, and various projects from the 2023 Student Cluster Competition


There are new hardware processes and programming paradigms that promise to dramatically improve process yields and performance. CXL will unlock academic research computing disciplines that currently have no solution path. These include deeply recursive codes and
applications that require large memory blocks.

Unified Acceleration (UXL), was announced last month at the Linux Foundation Open Source Summit with the goal of delivering a multi-architecture and multi-vendor software ecosystem for all accelerators based on open source standards. And Universal Chiplet Interconnect Express (UCIe) is helping to build an open ecosystem of chiplets for on-package


Shankar Viswanathan is the lead performance architect for AMD's Strategic Silicon products. He has worked on the design and verification of several generations of AMD processors. Most recently, he was on the design team for the SoCs that power game consoles such as the PlayStation5 and the Steam Deck. His general interests like at the intersection of performance and security in hardware platforms.
