hoohoo! Linus pulled a scream test and then forced the naysayers to maintain the crap they want. rofl
I’m far sadder to see the various MIPS machines starting to lose support than I am for Itanic.
Nah. The current license holder for MIPS announced its death a couple of years ago.
RISC-V is the new hotness.
And good riddance. They were technological marvels, but the continuously slipping release dates made them obsolete the day they were released.
They were interesting, but only good for a very narrow purpose - not really a good thing when the trend back then was going away from special purpose machines toward general purpose.
intel didn’t plan it to be just a special purpose CPU - but it just ended up that way. That they gave their first customers free Alpha workstations for crosscompiling code as that was faster than native compilation should tell you everything you need to know about suitability of itanic as general purpose system.
I never used Itanium, but I’m guessing that the Alpha workstations also ran x86 code faster than the Itaniums. fx!32 was one of DEC’s marvels that they completely forgot to market.
Yeah, but x86 was relatively cheap. Alpha and Itanium were in a similar price range.
At that time Alpha belonged to Compaq - and they stopped Alpha development (and canned quite a few good designs which were pretty much ready to go), expecting they’ll be able to replace it with Itanium.
Were they marvels, though? Itanium made good business sense in that it would cut AMD out of the market, but it was shit technology. Itanium would have also done a good job of cutting GCC out of the compiler market, which is great news for ICC. If everybody had to buy Intel compilers, boy that would have changed the software market.
You shouldn’t be making the compiler guess at conditions-on-the-ground that the CPU should be inferring itself, such as “which data dependencies are in cache and could be running OOO right now?”. You shouldn’t be making the compiler spend instructions and memory bandwidth describing this stuff. You shouldn’t be making code that works well on exactly one generation of CPU, one pipeline design, and is trash on the next generation. Once upon a time, MIPS saved a few gates by making three “delay slots” part of the ISA, and that became an albatross as soon as they weren’t a three stage pipeline. Itanium is all about making that kind of design decision everywhere. Itanium is the Microsoft Word of ISAs, where the spec is “whatever my implementation does is the correct thing”
The immediate failure of the Itanium was the promise that “you are buying a new, more expensive system that runs your current x86 code worse”, and the expectation was that every generation of Itanium would go like that. Just as your software starts getting good, here comes the new chip that will someday make stuff faster, but you will never see that until just about the end of that product cycle.
Is anyone actually running modern Linux on Itanium? I have never in my life even heard of anyone using those chips. I find it hard to imagine anyone still using them that isn’t running something legacy.
The last chip was manufactured 3.5 years ago and the last serious user was probably several years before that. Obviously no one’s running Itanium with modern hardware.
But just because the hardware isn’t modern, doesn’t mean the software can’t be modern. Tonnes of people run the most recent Linux kernels on 15 year-old laptops, so why not 10 year-old servers? Itanium is only for the hobbyists these days, but so what? Hobbyists have done a good job of ensuring modern Linux can run on 40 year-old 68k. Itanium can theoretically be done, too. It’s just a question of whether the hobbyist community has enough of the right people that can actually maintain it.
It wouldn’t surprise me if there were still a few production Itanium systems in server rooms somewhere, running some obscure or bespoke proprietary software that can’t be migrated to anything else. There are other more arcane systems still being limped along in businesses around the world, for some frighteningly critical applications in some case.
Itanium support being dropped probably has a handful of admins panicking, but in the eyes of the kernel developers it’s a case of “put up or shut up”.
running some obscure or bespoke proprietary software that can’t be migrated to anything else
this is the primary issue – everyone looks at corporations when talking technical debt, but so many medium and small businesses are limping along on so called “enterprise” solutions they were sold a couple decades back and are now completely locked into proprietary formats for which support ended last decade
Yeah. I know of ancient AS/400 and slightly less ancient RS/6000 systems still humming along, keeping insurance companies running.
But they probably haven’t seen software updates in decades. Linux 1.0 didn’t even exist when they were new, let alone 6.7.
It’s still a supported architecture in Gentoo. I expect it will limp along there for as long as there is viable kernel source (current or LTS) and at least one interested maintainer. So if you have an Itanium machine lying around, you can install a current Linux on it. As long as you’re willing to follow a long set of instructions, anyway.
It seems like NetBSD is working to support Itanium. https://wiki.netbsd.org/ports/ia64/
