Top500 Supers: This Is Peak Nvidia For Accelerated Supercomputers
If high bandwidth memory was widely available and we had cheap and reliable fusion power, there never would have been a move to use GPU and other compute engines as vector and matrix math offload engines. …

Top500 Supercomputers: Who Gets The Most Out Of Peak Performance?
The most exciting thing about the Top500 rankings of supercomputers that come out each June and November is not who is on the top of the list. …

How AI Is Going To Change Supercomputer Rankings Even More
The interesting thing about the June 2023 rankings of the world’s most powerful supercomputers is not how it really has not changed all that much in the past six months, or that the June list is coming out in May. …

At Long Last, HPC Officially Breaks The Exascale Barrier
Significant business and architectural changes can happen with 10X improvements, but the real milestones upon which we measure progress in computer science, whether it is for compute, storage, or networking, come at the 1,000X transitions. …

Top500 Supercomputers: Hungry For The Exascale Feast
Let’s just cut right to the chase scene. The latest Top500 ranking of supercomputers, announced today at the SC21 supercomputing conference being held in St Louis, needed the excitement of an actual 1 exaflops sustained performance machine running the High Performance Linpack benchmark at 64-bit precision. …

Waiting – Not Precisely Patiently – For Exascale
There was an outside chance that China might pull a surprise on the HPC community and launch the first true exascale system – meaning capable of more than 1 exaflops of peak theoretical 64-bit floating point performance if you want to be generous, and 1 exaflops sustained on the High Performance Linpack (HPL) benchmark if you don’t – but that didn’t happen. …

The Many Facets Of Hybrid Supercomputing As Exascale Dawns
There may not be a lot of new systems on the November 2020 edition of the Top500 rankings of supercomputers, but there has been a bunch of upgrades and system tunings of machines that have been recently added, expanding their performance, as well as a handful of new machines that are interesting in their own right. …
