I suppose you cannot really have determinism with SMP though
even if it's emulated? (don't know anything about this topic)

@raitobezarius:matrix.orgraitobezariusI don't know what you mean by emulated or see how it is relevant here18:45:50
@raitobezarius:matrix.orgraitobezariusBut if you linearize all the executions, then, yes, SMP can be deterministic18:46:05
@raitobezarius:matrix.orgraitobezariusBut it's not really SMP18:46:12
@aciceri:nixos.devzrsk anyway if someone wants to satisfy my curiosity and try to build a random derivation (I don't know, nix or hello maybe?) on an SBC and give me the time it takes (just the order of magnitude is enough) I would be grateful 18:48:35

Yeah don't worry, I've no really idea what I'm talking about probably. Thank you very much however :)

@aciceri:nixos.devzrsk Anyway I don't know if somebody already tried it but building RISC-V docker images with dockerTools.buildImage worked like a charm. I was impressed (as always) by Nix. 18:53:35

  • hello: 2m dominated by configure, likely faster on nvme
  • nix: I started the build, I'll let you know tomorrow

Not the best premises lol

Just tried hello and it takes 136s for me, probably using a Star64 as a builder is not worth it. In my case the disk speed wasn't the bottleneck surely (it's a fast nvme).

Your work there is great, do you keep images updated? Don't you host a cache also?

Then you can buy the MilkV
