Got any interesting questions to raise at the next #HPC Club?
Also can anyone get Tenstorrent or Arm to come along to this and take part on the panel?

@edzitron.com i'm sure you'll enjoy this one.
I really only persisted after the third or fourth attempt for entertainment value but now i feel bad for killing some polar bears. God knows how much leccy that burnt.

#HPC #Halloween
In racks of steel beneath the floor,
Where GPUs hummed forevermore,
The AIs trained from dusk till dawn,
Until the hype was dead and gone.
The traders fled, the quants withdrew,
As model weights were marked askew,
And venture dreams began to rot
The bubble burst, the funds forgot.

I'm have a weird problem on #AWS but only in eu-west-1 and eu-west-2.
We have some code that automates VM instance creation and then connects to the instance via SSH. Was working fine globally last week.
Now, any VM created in eu-west-1 or eu-west-2 is unresponsive. Can't SSH in to it.

If we're going to redo DC power cabling all over again why not do it right.
Wouldn't it be cool to have a PoE style protocol but with wiring and connectors gauged for 1MW? Plug in a single cable into a rack. If the protocol negotiates everything is fine you get power, else it stays off.

800V racks baby!
“Up to 5% improvement in end-to-end power efficiency
Maintenance costs reduced by up to 70% due to fewer PSU (power supply unit) failures and lower labor costs for component upkeep
Lower cooling expenses from eliminating AC/DC PSUs inside IT racks”

NVIDIA and 20 of its largest customers are preparing to r change how they power GPU clusters, enabling more efficient & powerful AI factories.
At OCP, NVIDIA says CoreWeave, Lambda, Nebius and Oracle are now designing for 800 VDC data centers.

Beyond the water that cools the servers, data centers indirectly contribute to water use through the electricity generation needed to power their operations.
That indirect use often makes up 80%+ of the overall water use.

I have a stupid idea. I know it must be stupid because I think it may involve blockchain. But I need some help figuring out why it’s stupid exactly. Oh the fact that I know nothing about security and this is a security related idea also guarantees it’s dumb. Please tell me why. /1
