Linus Torvalds on World Domination (x86 Servers)

Linus Torvalds pulls pin, tosses in grenade: x86 won, forget about Arm in server CPUs, says Linux kernel supremo
Linux kernel king Linus Torvalds this week dismissed cross-platform efforts to support his contention that Arm-compatible processors will never dominate the server market.
Responding to interest in Arm's announcement of its data center-oriented Neoverse N1 and E1 CPU cores on Wednesday, and a jibe about his affinity for native x86 development, Torvalds almost abandoned his commitment to civil discourse while doing his best to dampen enthusiasm for a world of heterogeneous hardware harmony.
"Some people think that 'the cloud' means that the instruction set doesn't matter," Torvalds said in a forum post. "Develop at home, deploy in the cloud. That's bullshit. If you develop on x86, then you're going to want to deploy on x86, because you'll be able to run what you test 'at home' (and by 'at home' I don't mean literally in your home, but in your work environment)."

Linus on why x86 won for servers

ARM announces Ares
I can pretty much guarantee that as long as everybody does cross-development, the platform won't be all that stable.
Or successful.
Some people think that "the cloud" means that the instruction set doesn't matter. Develop at home, deploy in the cloud.
That's bullshit. If you develop on x86, then you're going to want to deploy on x86, because you'll be able to run what you test "at home" (and by "at home" I don't mean literally in your home, but in your work environment).
Which means that you'll happily pay a bit more for x86 cloud hosting, simply because it matches what you can test on your own local setup, and the errors you get will translate better.
This is true even if what you mostly do is something ostensibly cross-platform like just run perl scripts or whatever. Simply because you'll want to have as similar an environment as possible,
Which in turn means that cloud providers will end up making more money from their x86 side, which means that they'll prioritize it, and any ARM offerings will be secondary and probably relegated to the mindless dregs (maybe front-end, maybe just static html, that kind of stuff).
Guys, do you really not understand why x86 took over the server market?

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
