The US Department of Energy’s Frontier supercomputer has been crowned world’s fastest at the International Supercomputing Conference 2022 in Hamburg, Germany, and is the first system to enter the exascale era of computing.Continue ReadingCategory: Comp… Continue reading Frontier breaks the exascale threshold to take top supercomputer spot
Cluster Your Pi Zeros In Style With 3D Printed Cray-1
From a performance standpoint we know building a homebrew Raspberry Pi cluster doesn’t make a lot of sense, as even a fairly run of the mill desktop x86 machine is …read more Continue reading Cluster Your Pi Zeros In Style With 3D Printed Cray-1
The Descendants of Ancient Computers
Building computers from discrete components is a fairly common hobby project, but it used to be the only way to build a computer until integrated circuits came on the scene. If you’re living in the modern times, however, you can get a computer like this running easily enough, but if …read more
Big Beautiful Vintage Computers, and Where To Find Them
[Ken Shirriff] recently shared some pictures and a writeup from his visit to the Large Scale Systems Museum, a remarkable private collection of mainframes and other computers from the 1970s to the 1990s. Housed in a town outside Pittsburgh, it contains a huge variety of specimens including IBM mainframes and …read more
