Woah! How is it the middle of October already? When did that happen?

Another first for our AI fleet... a supercomputing cluster of NVIDIA GB300s with 4600+ GPUs and featuring next gen InfiniBand. First of many as we scale to hundreds of thousands of GB300s across our DCs, and rethink every layer of the stack across silicon, systems, and software…


One side effect of having lots of LED light bulbs around the house is that you forget you have the occasional bulb that is still the old filament style and also that those filament bulbs get really hot really quickly. Anyway so I have a blister on my finger now.


The HPC (+ AI Infrastructure) Leadership Training Institute this week at BSC hit registration capacity weeks ago - extra places were opened & they went fast too, and people still on a waiting list. Nice to see the guess of demand to run the first ever HPCLI in Europe was good!

If intelligence is the log of compute… it starts with a lot of compute! And that’s why we’re scaling our GPU fleet faster than anyone else. Just last year, we added over 2 gigawatts of new capacity – roughly the output of 2 nuclear power plants. And today we’re going further,…

Boarding @British_Airways for Seattle … oh, nope, crew got on then back off again to say the aircraft hadn’t been cleaned at all, so now we all waiting at gate for estimated 40mins delay before boarding while aircraft gets cleaned.

Hearing the announcement: “boarding complete” for on time departure = good. Followed by pilot: “there is a fault with the aircraft so there will be a delay before we can go …” = less good.


Driving test currently has two parts - theory and practical - I reckon it needs a third part, an individual psychological profile - so can’t get driving licence if assessed as likely to drive dangerously or aggressively or recklessly etc.


Only 2 seats left! The 2025 HPC Leadership Institute in Barcelona is nearly full - register now if you want to secure one of last seats at the most recognized training for current or future leaders across #HPC including #AI, #cloud, #supercomputing, ... bsc.es/news/events/hp…

When people are afraid of change and disruption, they dig into the past with all of their might while adamantly denying the future. There was an error where teachers wouldn’t let you use calculators in math because supposedly it was gonna slow down. Learning in math has evolved…
