also turns out you cannot embed memes on zulip. Don’t try that at home :frown:

I consider that a feature :P

Jake Goulding (Nov 09 2018 at 14:28, on Zulip):

I don't understand which of those graphs is for Rust. They all list GCC options

RalfJ (Nov 09 2018 at 14:28, on Zulip):

I think the first is for Rust

RalfJ (Nov 09 2018 at 14:28, on Zulip):

no idea why it shows GCC options...

Jake Goulding (Nov 09 2018 at 14:29, on Zulip):

I guess it does say "rust prime" in the header

Jake Goulding (Nov 09 2018 at 14:30, on Zulip):

(a) it's interesting that Rust is being tossed into the general "check out this code" bucket
(b) that has to be all LLVM going it anyway, right?

nagisa (Nov 09 2018 at 14:58, on Zulip):

the interesting part here is the code being so much faster than on the top-of-the-line x86 CPUs (despite other benchmarks being less different)

nagisa (Nov 09 2018 at 14:58, on Zulip):

which at least tells me that the powerpc backend is not as unoptimised than I feared it to be

(for the reference 2990WX is a 32 core CPU vs 44 PPC cores over 2 sockets of TALOS)
