    Ah right, yes- I think we're talking about the same thing- this driver just chooses to pretend to be a RoCE v2 device (instead of e.g MLX Nic in IB mode), but nothing would change …

    Thanks and yes real infiniband works better I agree, but it's still hundreds of dollars and days (at best!) of time. This gives you 90% of the benefits with a cable you probably al…

    Yeah, thunderbolt-net is IP on top and it does work as you say, with a few caveats: - On a single cable with two rails available, the thunderbolt-net grabs one and uses that. Witho…

    I actually didn't know there was more to InfiniBand than verbs (at least at this abstraction level, above PHY), so probably the answer is 'not much more'. The device imitates a RoC…

    A USB4 40Gbps cable consists of two 20G tx/rx pairs. The in-kernel networking implementation is single-stream and just uses one pair, and won't e.g. stripe across both pairs or acr…

    author here! it's not on top of USB4NET, no (RXE can already do that, it's compared in the benchmarks). it's built with the same tb primitives as the networking stack obviously, ju…

    No, you can tell it not to write these comments in every prompt and it'll still do it

    I don't think Threadripper platform is to blame that you bought a board with potentially the worst possible pcie lane routing. Latest generation has 88 usable lanes at minimum, mos…

    why make this- because people like music? I want to use it to make my own music, according to you, I can't because it deprives some /real/ musician of making money? what an insane …

    Interesting, thanks. Whilst ".2G Twice a week, for 6 months" doesn't strike me as a lot- could be someone who just goes clubbing twice a week- apparently enough to cause brain lesi…

    My comment wasn't implying that importance of wind in the UK energy mix (or lack of investment in nuclear) is specifically the reason for high costs but I agree that government pol…

    That's great- but UK has almost highest energy cost in Europe- almost €0.48/kWh. By comparison France (which has consistently invested in nuclear for the past half-century) has alm…

    If anyone wants to add remote access capability to machines without IPMI you can try with something like the $30 RISC-V NanoKVM[1][2]. It provides HDMI capture (and encoding), Ethe…

    I bought one of these boards a few weeks ago, it uses the mobile version of the CPU, great performance and low power usage. https://cwwk.net/products/cwwk-amd-7735hs-7840hs-8845hs-…

    Great news- if you're a fan of Nassim Taleb: "I've seen gluts not followed by shortages, but I've never seen a shortage not followed by a glut."
