#NOAA ditches weather-predicting #supercomputers for #GoogleCloud
#US Government agency will use Google Cloud H4D VMs to replace #HPE #Cray machines
General Dynamics held the previous contract for managing NOAA’s weather predicting machines, which most recently were HPE Cray supercomputers running in data centers in Virginia and Arizona. Those machines – Dogwood and Cactus – could crank almost 14 PFlops of weather-predicting prognosis.

81920 Cores Per Rack with #AMD #EPYC Venice at #HPEDiscover 2026
While we are talking about 8000 cores being decently dense in an air-cooled rack today, these #HPE #Cray nodes are aiming to be roughly 10x as dense. Perhaps more exciting is that this looks like a working system. Specifically an #HPECray #GX250a Compute Blade with AMD EPYC Venice.There are small Samsung E1.S EDSSF SSDs on top of the CPU coldplates, and the network is #Slingshot400.

Long distance relationship with an Cray

As I changed cities from Munich to Rostock, the last physical connection happened to be the shutdown of the Cray Y MP-EL.

But we finally did test the connection we built to reach it remotely. So, if the Ethernet AUI connector is really plugged in, I'm able t

Holy crap! It's got #Unicos too! I shall resurrect my project from 1999 to get #bzip2 to support #Cray!

(the bug is that bzip2 insists (insisted?) that `short` be 16 bits)

Un supercalculateur Cray T3D de 1993 est à vendre. Un des ordinateurs les plus puissants du monde à l'époque : 512 CPU DEC Alpha à 150 MHz. 76,8 GigaFLOPS. 3 tonnes. 1,93m de haut pour 117cm de large. 7000 fois plus puissant qu'un Amiga 4000... mais moins puissant qu'un smartphone actuel. Mon MacBook Pro M1 Pro 10 cœurs de 14 pouces est environ 65 fois plus puissant que ce mammouth ! https://www.the-saleroom.com/en-gb/auction-catalogues/rwb-auctions/catalogue-id-rwb-au10062/lot-2c400ee1-8fbd-455b-abb4-b43c00a73576 #RetroComputing #Cray #Amiga4000 #TechHistory #MacbookPro

Всё, что вы хотели узнать о Хабре, но боялись спросить

В одной из тихих комнат интернета недавно произошёл маленький научный эксперимент. Эксперимент был поставлен без лаборатории, без белых халатов и даже без гранта. Достаточно было двух статей. Первая статья была серьёзная:

Cray: оживление легенды

В ИТ-индустрии существуют вещи, само существование которых давно стало красивым мифом, о котором принято вспоминать лишь шепотом и закатывая глаза от благоговения.

Cray collection

we collected a bunch of Crays. The Y-MP EL in front is currently working, the others behind will be restored one day.

Collection of Crays

Crays and Cybers

These two will only be for display, but won't be running again.

From time to time I need to lookup some rarely used vi commands. Good to have a vi reference card laying around at my desk 😀 #vintagecomputing #cray #vi #unicos

When you unpack the tarball of gcc-2.9 and start compiling and it stops with the strange error, that the built stuff is older than the content of the tarball. Welcome on my #Cray, which remains in 1993.
So had to touch a lot of files to get them back to history lane.... #datArena

If I had realised yesterday that it was Seymore Crays 100th birthday then I would have definitely posted these selfies I took at #TNMOC 5 years ago, and a link to my Crayzee Eighty too https://rc2014.co.uk/1865/crayzee-eighty/
Instead, I will do that to celebrate 100 years and 1 day since #Cray was born :-)

Perl on a Cray Y-MP EL

Compiling Perl on a Cray is not an easy task, if you only have a few hours every Tuesday. And taking a Cray home, even the little Y-MP EL, is not an option. Neither is letting it run unattended.

The frustrating part is the wait. Unicos does not even have a 'top' command, so ps -efa is your best friend
