Los Alamos Pushes The Memory Wall With “Venado” Supercomputer
Today is the ribbon-cutting ceremony for the “Venado” supercomputer, which was hinted at back in April 2021 when Nvidia announced its plans for its first datacenter-class Arm server CPU and which was talked about in some detail – but not really enough to suit our taste for speeds and feeds – back in May 2022 by the folks at Los Alamos National Laboratory where Venado is situated. …

The Skills Gap For Fortran Looms Large In HPC
Back in the dawn of time, which is four decades ago in computer science and which was before technical computing went mainstream with the advent of Unix workstations and their beefy server cousins, the computer science students we knew at college had taught themselves BASIC on either TRS-80s or Commodore VICs and they went to college to learn something useful like COBOL and maybe got a smattering of C and Pascal, or occasionally even RPG, for variety. …

Opening Up The Future “Venado” Grace-Hopper Supercomputer At Los Alamos
There are many interpretations of the word venado, which means deer or stag in Spanish, and this week it gets another one: A supercomputer based on future Nvidia CPU and GPU compute engines, and quite possibly if Los Alamos National Laboratory can convince Hewlett Packard Enterprise to support InfiniBand interconnects in its capability class “Shasta” Cray EX machines, Nvidia’s interconnect as well. …

Sneak Peek At “Sapphire Rapids” Xeons In “Crossroads” Supercomputer
Managing an aging nuclear weapons stockpile requires a tremendous – and ever-increasing – amount of supercomputing performance, and the HPC system business the world over is focused on this as much as trying to crack the most difficult scientific, medical, and engineering problems. …

Nvidia Enters The Arms Race With Homegrown “Grace” CPUs
There has been talk and cajoling and rumor for years that GPU juggernaut Nvidia would jump into the Arm server CPU chip arena once again and actually deliver a product that has unique differentiation and a compelling value proposition, particularly for hybrid CPU-GPU compute complexes. …
