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 if it did I think. Or at least thats what the libibverb

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 already own

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. Without patching the kernel, there's no way to make it prese

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 RoCE V2 device and the higher level abstractions

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 across multiple cables, which was the main bandwidth

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, just assembled differently to emulate a verbs d

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, most boards have 4x 16x, and Pro supports 7x Gen 5.0 x16 l

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 argument- ban singing unless you're in a

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 lesions. Anyone know if the study is reputable, o

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 policy is indeed to blame. As to whether the cause is Tory

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 almost half that. Until UK has enough energy that it

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), Ethernet/Wifi, ATX power control, and runs a normal linux d

My guess is that it's a similar social phenomenon to flat-earthers, qanon, etc, in that a group of like-minded people form and customs emerge in which making ever-more outlandish claims are taken as stronger commitment signal to the gr
