Depends on what shit you're using.
From this side it looks more like this to me:
"Here comes the snakeoil peddlers... One remedy to cure...

It's hard to fix stuff you don't understand. ...

[milkylainen]

I guess by now it's pc to say the Intel solutions are screaming "Help! I'm getting raped!" come the perf*dollar charts...

[milkylainen]

Absolutely. I fully agree. They don't have to be context equals. I already explained that. There is little need for the CPU to be context equal to the...

[milkylainen]

Correct. 150G/sec single direction. 300G/sec bidirectional. Maybe I misunderstood you?
PCIe 4.0 is 32G single direction, 64G bidi. 5.0 will be 64G...

[milkylainen]

As much as I love optimizations I get mixed icky feelings when beautiful kernel code (arch or not) is tainted with way to much knowledge.
There...

[milkylainen]

Yes you are right. Most if not all modern GPUs will have a full coerency state inside.
They have both MMUs, IOMMUs and they have multiple executing...

[milkylainen]

First I'll answer your questions.
Yes. NVidia will push NVLink 2.0 and higher. It simply outclasses PCIe for compute applications.
CXL might...

[milkylainen]

It sure can.
But if you run it on SMB the aliens will have Pew-pew guns and dance like Steve Ballmer.
If you run it on NFS then the aliens...

If Elon would have named the feature it would have been called "Kernel Pucker Factor" with a 1-10 scale. :]

[milkylainen]

I don't understand the objection. Of course there is practical reason behind the work?
There are a lot of Windows or Linux servers running CIFS...

[milkylainen]

Actually I anticipated a whole different set of tests.
Running full software suites on the kernel isn't going to reveal much at all.
Individual...

[milkylainen]

Hardly much point running a full stack testsuite. There will minor differences only.
Individual synthetics on the kernel are much more useful at...

[milkylainen]

Because humans are like magpies. Shiny shit always seems more attractive than dull shit.
99% of people aren't smart enough to differ between anything...

[milkylainen]

You mean why PCIe does not cater to low-latency and other types of needs?

Because bus development was mainly PC driven. You need bandwidth...

[milkylainen]

Terminology. All these standards use the same SerDes. They are lane-speed equivalents.
Essentially NvLink is PCIe and vice versa.

Difference...

[milkylainen]

I don't agree. It's like saying that gzip speed and compression suits everyone.
x264 is pretty slow, even in crap settings.
But x264 is actually...

SVT is one of Intels ongoing efforts to make "Software instead of Hardware" solutions to problems.
If they were serious about it they...

[milkylainen]

Thanks for the correction. I totally misread what was being fixed and threw an unjustified hizzy fit. ...

[milkylainen]

Ok. My bad. The apparently fubared quick readup was interpreted as as "fixing the SLAB allocator"....
