Video Description
Supercomputing is the massive high-performance computing (HPC) conference where industry meets academia to showcase the cutting edge of supercomputers and academic research. In this video, I go through the "melange" of everything I saw on the SC25 show floor in St. Louis, from 100T switches and optical chiplet demos to next-gen vector engines and the latest Blackwell hardware.
