blopeuron Japan Captures TOP500 Crown with Arm-Powered Supercomputer

A64fx have on board HMB -> that means no dram. If you look at the fugaku mother board their is no Dimm slots. All the memory is on the same package as the CPU.

This delivers a huge boost in bandwith.

HMB stand for high memory bandwidth. It offers up to 900 GB/s.

Now if you add the tofu interconnect on top you have a systems finely tuned for maximising data movement.

Remember : compute is cheap, communication is expensive.

You can have load of gpu and processors but if you can't feed them data fast enough they are useless.

blopeuron Gaia-X: Technical Architecture [pdf]

From the doc: "GAIA-X itself does not act as a billing provider or clearing house. But GAIA-X will define standard interfaces and mechanisms for metering to be used by the Consumers and Providers. "

Yea.. so basically you have a catalogue but it's going to be up to the consumers or providers to find a way to stitch up a clearinghouse solution for dynamically orchestrated services from a multitude of providers. This is not only hard. It's near impossible. Without this crucial element, the platform is stillborn.

blopeuron Germany, France launch Gaia-X platform in bid for ‘tech sovereignty’

This project is still born because they are missing a federated accounting and payment service at the heart of the platform.

Why? Because it's damn near impossible to deliver such feature for dynamically orchestrated services from a federation of providers.

Sovereignity, interoperability, compliance is a nice sales pitch. But it seems that when it comes to getting paid or paying you are on your own. Imagine trying to pay for hundreds of services from companies spread across dozens of countries...

blopeuron Nvidia CEO Introduces Nvidia Ampere Architecture, Nvidia A100 GPU

I am suspecting that this is specifically targeted at the HPC market as the lack of FP64 has always been a hindrance to HPC deployment.

You have to remember that the HPC market is $35B today. HPE makes $3B a year alone from that, maybe more with Cray acquisition.

So it's no surprise that NVIDIA wants to position themselves on that market.

Plus, you have too look at the long game with MLX acquisition ( heavy player in the HPC market) and Cumulus. I wouldn't be surprised to see NVIDIA trying to bypass Intel/AMD completely and offer Direct to Interconnect device. Rather than the hybrid CPU + GPU box.

"Our results show that when hyperparameters are properly tuned via cross-validation, most methods perform similarly to one another"

"...this brings into question the results of other cutting edge papers not covered in our experiments. It also raises doubts about the value of the hand-wavy theoretical explanations in metric learning papers."
