The "AI" phenomenon and craze has been discussed endlessly, including the vast computational and energy requirements of dedicated #datacenters

There is an important split betwen model building and inference of statistical models (and hence also #llm ) which means there is not one but two problems to solve.

The first one is *highly* non-trivial. It bumps against #mooreslaw and requires #supercomputing networking tricks. The datacenter must operate as one giant machine

Wall Street Journal: The quest to use AI to help find new drugs. “Lilly first announced a partnership with chip-maker Nvidia in October to build what it called the industry’s most powerful supercomputer, and expanded that in January with a $1 billion, five-year collaboration mixing their scientists and engineers in a new Bay Area lab aimed at discovering new medicines with AI tools. They […]

An international team of physicists, including researchers from Jülich, used supercomputers to deliver a new high-precision calculation of the muon’s magnetic moment ⚡🧬

The result reduces theoretical uncertainty and strongly validates the Standard Model of particle physics.

The paper appeared in Nature.

Do you have vast amounts of #data that you need to #analyse for #research #science or #business ? If so, we recommend this online webinar: It introduces EXA4MIND, an platform that combines top #supercomputing resources in #Europe with practical analysis tools and #databases . LRZ researchers explain its capabilities and offer many tips for using it: https://www.youtube.com/watch?v=8csioAlK7bs&t=1s

Instead of installing Arbiter2 on our login nodes to police users, I've taken a slightly different approach of using a systemd user slice to "jail" users!

Don't get me wrong, Arbiter2 is a complete solution, I just prefer simplicity.

Anyways, the idea is based from the URL https://unix.stackexchange.com/questions/732408/configure-cgroups-v2-for-fair-resources-sharing-between-users . I simply have a script that prompts for a username, checks if it is valid or not, and creates the "template" jail. One still needs to run daemon-reload, and sync to other login nodes if need be.

Best part, you can simply delete the created slices to release the users from jail. Feel free to use/modify, IDGAF: https://s3.enemy.org/~mrfusion/jail_user.txt
