AMD is continuing to expand its presence in both the consumer and enterprise markets. Their Epyc processors are finding their way into some interesting supercomputers. The new Atos BUllSequana XH2000 will use AMD Epyc 7742 processors. The XH2000 is a weather predicting supercomputer. The Epyc 7742 is a 64c/128t that has 225w TDP.

In November AMD scored another contract with AWE or the Atomic Weapons Establishment. Those super computers are using a combination of Cray technology along with the AMD Epyc 7542 processors. The Epyc 7542 is a 32c/64t that has 225w TDP.

In October the UK Research and Innovation, UKRI, used them for the new Archer 2 supercomputer. This time around using dual AMD Epyc Rome 64 core processors. The first Archer used the Cray XC30 in 2013 and used for general research.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
