Found out why they aren't letting robots into sports.

my buddy @0xkruzr@federation.engineering
pointed out all of their processors were found to be heavily doped 😔

Fun work thing: colleague of mine is putting out a series of posts on reverse engineering the old esperanto ETSOC1 before we open source part of the RTL!

@geerlingguy@mastodon.social *extremely* curious if/when you can enable more ports. Currently only having half the endpoints selected isn't super fun

@geerlingguy@mastodon.social @never_released@mastodon.social ... QSFP 100 Gbe ports. Assuming bus bandwidth isn't the issue causing the RDMA enabled port limitations, the clustering setup then becomes 2 ports/device to upstream backhaul switching, and each Mac being connected All2All within a 4 device topology

@geerlingguy@mastodon.social Slightly strange: A few minutes in there's a comment on how RDMA can only be enabled on 3 of the ports because of a naming conventions? CC @never_released@mastodon.social That seems extremely strange to me. Suspect it's time to update this post: https://gist.github.com/FCLC/6e0f0e79e9d4f5740573f09d7579eb72 Even with that limitation, you should still have 3 more TB5 ports on the M3Ultra devices. Suspect the switch clustering side can be addressed using these: https://shop.atto.com/products/thunderlink-eu-model-5102-dual-port-thunderbolt%E2%84%A2-5-to-qsfp28-lc-optical-100gb-ethernet-adapter?_pos=7&_fid=69a565b99&_ss=c Turns a pair of TB5 ports into a pair of ...

Really cool: @geerlingguy@mastodon.social got a cluster of MacStudios to test out apple's thunderbolt RDMA infrastructure!

That’s a wrap on #SC25, spending time with so many of my favourite people on the planet. While HPC is known for what it makes, what makes HPC is the community.

See you all in Chicago for #SC26.
