Someone who want's to make an estimate as to world electricity cost based based on efficiency losses?

[milkylainen]

Nah. Summarizes the technology. So-so-SMT. ...

[milkylainen]

Sure. But the whole point of this library seems to be to increase benefits of having new shiny vector units.
So while you are right, what would...

[milkylainen]

Now that is a beautiful change! Core functionality speedup to the benefit of just about everybody.
Interesting times for 5.2 indeed.

[milkylainen]

Super interesting. Any chance Raptor boards will expose the Power CPUs NvLink in the future?
I'd sell my kingdom and all my horses for playing with...

[milkylainen]

I think China is doing it right. It's a really clever way of gaining trustworthy performance without redoing it from scratch.

They are accessing...

[milkylainen]

Ah. Thank you. Never used. I guess it would depend on the hardware but I don't see why it couldn't be done. Pass-through etc doesn't really depend on...

[milkylainen]

That summarizes most of it pretty nicely. Thanx. Some epic crippling of performance there.
As usual. Cheating pays off. Until you get caught. Then...

[milkylainen]

What do you mean? An application? What kind of application?...

[milkylainen]

That's a serious enhancement. Wonder if it's possible to bounce data without the DMA-controller though? Ergo, inbound, bounce, outbound. The bounce could...

[milkylainen]

Are these patches to be mainlined or have they been rejected? I see some stuff that is quite dubious.

[milkylainen]

There will always be regressions when changing complex core code.
Personally I'd rather break an egg or two once in a while over polishing a turd...

[milkylainen]

Umm. M$. Can I have your kernel source tree and all the modifications you have made please?

[milkylainen]

Then please explain the announcement?
"This optimization comes by using SIMD load/stores rather than GPRs for large overlapping forward moves."...

[milkylainen]

The statement really says nothing about the system memory topology.
Only that they have increased the possible number of unified memory controller...

[milkylainen]

Umm. Why not make it AArch64-generic? I understand these are custom AArch64 SoCs but they do adhere to the ARM v8 ISA do they not?
Hate to be the...

[milkylainen]

That looks like it could be a decent raise of the bar from GCC 9.x. Nice!

[milkylainen]

This has nothing to do with the article. Just a reflection on my monitor wish-list.
A lot of monitors seem to tick a lot of boxes for people in...

[milkylainen]

I did. Tried a whole bunch of compressors/decompressors with various options. gz, bz2, xz, lzop, zstd with various parallel decompressors or not.

Gcc + all the shiny Glibc math speedups?
