HPC Precision Wars: Satoshi Matsuoka Plants the Ozaki Flag

From the FP64 is not as boring as it used to be department

A recent paper submitted to ArXiv by famed HPC scientist Satoshi Matsuoka, Director of the RIKEN Center for Computational Science in Kobe, Japan, has shaken the tried-and-true FP64 HPC relationship to its core. The paper is entitled: FP8 is All You Need (Part 1): Debunking Hardware FP64 as the HPC Holy Grail: A Tensor–Memory Equilibrium Model and Implementation Strategy for Ozaki Scheme II on Memory-Bound Workloads in the Post-FP64 Era.

There is quite a lot to unpack in the paper, let alone the title. Matsuoka is basically positing that FP64 (64-bit double-precision arithmetic) hardware is not the best way to perform certain HPC computations that require 64-bit precision on newer Nvidia GPUs. Instead, he demonstrates how FP8 (8-bit floating-point operations) found in abundance on modern GPUs can be combined using the Ozaki Scheme II to achieve faster computation at the same 64-bit precision. This rebuke of legacy 64-bit floating-point technology is Matsuoka's flag-in-the-sand moment, and it will have consequences throughout the HPC industry. This article attempts to summarize some of the paper's major points; however, consulting the paper provides greater breadth and support for Satoshi's arguments and predictions.

Genesis Content: Where Does GenAI Get Its Next Meal?

From the well if you think about it department

Something about building GenAI LLMs bugs me. Before I begin, let me be clear: I am a supporter of AI technologies, particularly in science. Lately, however, a question keeps surfacing that I find hard to understand. GenAI promoters and sellers like to talk about "AI for Business" as a way to reduce costs and replace workers. Well, okay, all new technologies have that effect to some extent, but the GenAI industry seems to be touting GenAI as a replacement for the people who created the genesis content on which their technology was created. On the surface, this seems absurd; on closer inspection, it seems almost self-destructive. Talk about burning the ships while still at sea. There are many sectors where this question hits hard, but two specific topics of interest to me as a technical writer and sometimes programmer are content creation and programming.

HPCwire Gets a New Logo and Website

As a capstone to its rebrand, Tabor Communications (now TCI Media) launched a new website with extensive sections dedicated to HPC, AI, Big Data, and Quantum Computing coverage. The site was designed to encourage readers to explore topics related to the articles they are reading, with the aim of exposing them to the information they’ll soon need to become acquainted with as these disciplines continue to converge.

A (mostly) Non-Technical AI Primer

from the long, but worthwhile article department

I have studied and watched artificial intelligence grow over the last forty years. Like many, back in 1968, I was inspired by HAL 9000 in Stanley Kubrick's 2001: A Space Odyssey. The question on my mind at the time was, "Is HAL 9000 possible?" Thus began my interest in learning all I could about computers and something called Artificial Intelligence.

By 1970, my excitement grew when I read a quote by AI pioneer Marvin Minsky (in Life magazine), "In three to eight years, we will have a machine with the general intelligence of an average human being." The future was so bright I was beyond inspired.

We Are Back and the Beowulf Bash at SC25 in St Louis

Hello, is this thing on? We back on-line after a 2 year hiatus! Well, not because I did not want to post here, but I could not find the time to post the insightful content you expect from a free web site. Also, we don't use AI, never will for that matter. So someone actually has to type on a keyboard.

In any case, please go to the bash web page (we d work very hard on these things) and have a look at this years theme, complete with snarky content and foot notes.
