Intel Shows Off 80-core Processor 222

Posted by Zonk

thejakebrain writes "Intel has built its 80-core processor as part of a research project, but don't expect it on your desktop any time soon. The company's CTO, Justin Rattner, held a demonstration of the chip for a group of reports last week. Intel will be presenting a paper on the project at the International Solid State Circuits Conference in San Francisco this week. 'The chip is capable of producing 1 trillion floating-point operations per second, known as a teraflop. That's a level of performance that required 2,500 square feet of large computers a decade ago. Intel first disclosed it had built a prototype 80-core processor during last fall's Intel Developer Forum, when CEO Paul Otellini promised to deliver the chip within five years.'"

        Indeed, but only with Vmware and/or OpenVZ. ;-)

        Seriously, this thing doesn't even support the x86 instruction set (yet?), and is not form-factor compatible with today's processors.

        When it finally comes out, hopefully they will have integrated the "3D" chip-stacking tech into it as well, and HOPEFULLY it will run both cooler and with less power requirements than today's offerings.

    It's known incorrectly.

    The measurement is "FLOPS". Floating Point Operations Per Second. It's an acronym. The 'S' is part of the acronym. Hence even if you only have oneof them, it's still a FLOPS. And it's capitalised.

    Strictly speaking it should be "trillion FLOPS" as well since it's not an SI unit but my pedantry is limitted.

          That might not be a terrible idea. Since the utility of this chip assumes fine-grained parallelism anyways, the new metric would have to be flops per transistor. Implement the 486 design with modern process technology, thus allowing you to put 250 of them on a single chip runing at 100x the original clock speed of 33mhz, and you might get something very nice. Or is that even possible?

      Core2 has 2 or 4 Mbyte l2 cache. 1 bit cache is 6 transitors == more than 200 of those 291 million transistors are high-density cache. (Density of cache is a lot higher than that of logic, which the 80 core cpu nearly solely is made of).

      I thought that was a little weird, too. But the 80-core chip could simply have more wires (and therefore, fewer transistors). Given that they mention that there are routing elements between the cores, it's possible that a lot of the chip's real estate is taken up by massive busses between adjacent cores.

      Another explanation might be that they didn't want to waste the time/expense to come up with an optimized layout, or that they intentionally spaced things out to make testing easier.

    Fuck Everything, We're Doing Five Blades

    By James M. Kilts
    CEO and President,
    The Gillette Company

    Would someone tell me how this happened? We were the fucking vanguard of shaving in this country. The Gillette Mach3 was the razor to own. Then the other guy came out with a three-blade razor. Were we scared? Hell, no. Because we hit back with a little thing called the Mach3Turbo. That's three blades and an aloe strip. For moisture. But you know what happened next? Shut up, I'm telling you what happened--the bastards went to four blades. Now we're standing around with our cocks in our hands, selling three blades and a strip. Moisture or no, suddenly we're the chumps. Well, fuck it. We're going to five blades.

    Sure, we could go to four blades next, like the competition. That seems like the logical thing to do. After all, three worked out pretty well, and four is the next number after three. So let's play it safe. Let's make a thicker aloe strip and call it the Mach3SuperTurbo. Why innovate when we can follow? Oh, I know why: Because we're a business, that's why!

    You think it's crazy? It is crazy. But I don't give a shit. From now on, we're the ones who have the edge in the multi-blade game. Are they the best a man can get? Fuck, no. Gillette is the best a man can get.

    What part of this don't you understand? If two blades is good, and three blades is better, obviously five blades would make us the best fucking razor that ever existed. Comprende? We didn't claw our way to the top of the razor game by clinging to the two-blade industry standard. We got here by taking chances. Well, five blades is the biggest chance of all.

    Here's the report from Engineering. Someone put it in the bathroom: I want to wipe my ass with it. They don't tell me what to invent--I tell them. And I'm telling them to stick two more blades in there. I don't care how. Make the blades so thin they're invisible. Put some on the handle. I don't care if they have to cram the fifth blade in perpendicular to the other four, just do it!

    You're taking the "safety" part of "safety razor" too literally, grandma. Cut the strings and soar. Let's hit it. Let's roll. This is our chance to make razor history. Let's dream big. All you have to do is say that five blades can happen, and it will happen. If you aren't on board, then fuck you. And if you're on the board, then fuck you and your father. Hey, if I'm the only one who'll take risks, I'm sure as hell happy to hog all the glory when the five-blade razor becomes the shaving tool for the U.S. of "this is how we shave now" A.

    People said we couldn't go to three. It'll cost a fortune to manufacture, they said. Well, we did it. Now some egghead in a lab is screaming "Five's crazy?" Well, perhaps he'd be more comfortable in the labs at Norelco, working on fucking electrics. Rotary blades, my white ass!

    Maybe I'm wrong. Maybe we should just ride in Bic's wake and make pens. Ha! Not on your fucking life! The day I shadow a penny-ante outfit like Bic is the day I leave the razor game for good, and that won't happen until the day I die!

    The market? Listen, we make the market. All we have to do is put her out there with a little jingle. It's as easy as, "Hey, shaving with anything less than five blades is like scraping your beard off with a dull hatchet." Or "You'll be so smooth, I could snort lines off of your chin." Try "Your neck is going to be so friggin' soft, someone's gonna walk up and tie a goddamn Cub Scout kerchief under it."

    I know what you're thinking now: What'll people say? Mew mew mew. Oh, no, what will people say?! Grow the fuck up. When you're on top, people talk. That's the price you pay for being on top. Which Gillette is, always has been, and forever shall be, Amen, five blades, sweet Jesus in heaven.

      Blade Inflation
      By Dave Barry

      What's next from the razor-sharp minds of the shaving industry?

      Attention, consumers with bodily hair: The razor industry has news for you! You will never in a million years guess what this news is, unless your IQ is higher than zero, in which case you're already thinking: "Not another blade! Don't tell me they're adding ANOTHER BLADE!!"

      Shut up! Don't spoil the surprise for everybody else!

      Before I tell you the news, let's put it in historical context by reviewing:

      THE HISTORY OF SHAVING

      Human beings are one of only two species of animals that shave themselves (the other one is salamanders). The Internet tells us that humans have been shaving since the Stone Age. Of course, the Internet also tells us that hot naked women want to befriend us, so we can't be 100 percent sure about everything we read there.

      But assuming that www.quikshave.com/ timeline.htm is telling the truth, Neanderthal Man used to pluck his facial hairs "using two seashells as tweezers." No doubt Neanderthal Woman found this very attractive. "You smell like a clam," were probably her exact words. It was during this era that the headache was invented.

      By 30,000 B.C., primitive man was shaving with blades made from flint, which is a rock, so you had a lot of guys whose faces were basically big oozing scabs. The next shaving breakthrough came when the ancient Egyptians figured out how to make razors from sharp metal, which meant that, for the first time, the man who wanted to be well-groomed could, without any assistance or special training, cut an ear completely off.

      This was pretty much the situation until the late 19th century, at about 2:30 p.m., when the safety razor was invented. This introduced a wonderful era known to historians as "The Golden Age of Not Having Razor Companies Introduce Some Ludicrously Unnecessary New Shaving Technology Every 10 Damn Minutes."

      I, personally, grew up during this era. I got my first razor when I was 15, and I used it to shave my "beard," which consisted of a lone chin hair approximately one electron in diameter. (I was a "late bloomer" who did not fully experience

      puberty until many of my classmates, including females, were bald.) My beard would poke its wispy head out of its follicle every week or so, and I, feeling manly, would smother it under 14 cubic feet of shaving cream and lop it off with my razor. Then I would stand in front of the bathroom mirror, waiting for it to grow again. Mine was a lonely adolescence.

      The razors of that era had one blade, and they worked fine; ask any older person who is not actively drooling. But then, in 1971, a very bad thing happened: Gillette, looking for a way to enhance the shaving experience (by which I mean "charge more") came out with a razor that had TWO blades. This touched off a nuclear arms race among razor companies, vying to outdo one another by adding "high-tech" features that made the product more expensive, but not necessarily better. This tactic is called "sneakerization," in honor of the sneaker industry, which now has people paying upwards of $200 a pair for increasingly weird-looking footwear boasting the durability of thinly sliced Velveeta.

      Soon everybody was selling two-blade razors. So the marketing people put on their thinking caps, and, in an astounding burst of creativity, came up with the breakthrough concept of: THREE BLADES. Gillette, which is on the cutting edge (har!) of razor sneakerization, currently has a top-of-the-line three-blade razor -- excuse me, I mean "shaving system" -- called the "Mach3Turbo," which, according to the Gillette Web site (www.gillette.com) has more technology than a nuclear submarine, including "open cartridge architecture" and an "ergonomic handle" featuring "knurled elastomeric crescents." That's right: It has elastomeric crescents, and they have been knurled! By knurlers! No, I don't know what this means. But it sure sounds technological.

      Which brings us to today's exciting news, which was brought to my attention by alert reader Jake Hamer. Gillette's arch-rival, Schick (maker of the Xtreme 3 shaving system) has announced that it's coming out with a new razor that has -- prepare to be floored by innovativeness -- FOUR BLADES. Yes! It will be called the "Quattro," which is Italian for "more expensive."

      Of course it will not end there. I bet an urgent memo has already gone out in Gillette's marketing department. "Hold some focus groups immediately!" it says. "Find out what number comes after four!"

      Yes, the razor-technology race shows no signs of slowing. And who knows what lies ahead? Razors with 10 blades? Twenty blades? A thousand blades? Razors that go backward in time and shave your ancestors? Exciting times lie ahead, shaving consumers!

      "This isn't a general purpose processor."

      ...Yet. You're right in the fact that these cores are incredibly simplistic, so much so that they make DSPs look functional, but really what's going on here is a science project to develop the on-chip network, not to develop the CPU cores as much. Intel envisions lifting the networking component out of this design and applying it to various different cores, so that a general computing core can be mixed in with DSP cores and other "Application Specific Accelerator" cores.

      So no, this model you're not going to be running Firefox or your text editor on (in fact, I doubt you even _could_ do this, these cores currently are very, very stripped down in their capacity to do work, to where they're basically two MACs tied to a small SRAM and a "network adapter"), but never-say-never, this style of chip is right around the corner.

    It's useless to keep putting more cores into a processor when we still don't have a decent parallel programming paradigm.

    80 cores is an absurd number, with the parallelism level that we have in today programs, most of the cores should be idle most of the time.
    • I really don't understand this idea that we "can't use multiple cores yet" because we don't have some magical, mythical necessary programming model that will make this come alive instantly. The fact is, we've had the necessary models for decades now. Adding multiple cores doesn't necessarily mean we need to change our programs at all, but rather it means we need to change our Operating Systems.

      To the point: right now, we typically schedule applications to run on time-slices, to virtually expand one proce

      Eight of these processors ought to be enough for anyone.

    Hmm has it really taken 20 years of research or ... Wonders... 20 years later... Patents...?

    There ya go. Think of it as a benchmark. How long can the 80-core processor run that without dying?

    • The death comes from process tables filling up, so I suspect the 80 core processor will die faster.

      How fast can it die, or how long does it remain responsive? It is, after all, memory that leads to the eventual death ;)

  • [a teraflop is] a level of performance that required 2,500 square feet of large computers a decade ago.

    Over a decade and a half ago, in 1990, I programmed parallel AT&T DSP32C boards (multiple DSPs per ISA board in an 80386 host). Up to 5 25GFLOPS chips on a 125GFLOPS board, up to 8 boards in a 1TFLOPS host PC. That PC, nearly double the "decade ago", had over 1TFLOPS (including its FPGA glue) in about 3 square feet.

    And it actually ran applications (commercial image processing) in the field. This Intel

  • also does it have a ram controller build in?
  • My concern isn't that they can cram 80 processors of some capability onto a single chip (how many i486 processors could you put on the current Core 2 Duo die and transistor budget at 65/45nm?), but how can you feed enough data on and back off the chip to keep these processors running at near full speed? 8000 processors on a chip are worthless if they can't get to their data.

    And I'm not impressed by the Flop rate. Not with the Cell Processor already out for a year.

    Well, those shitty, basic computers that took up big rooms, remember those? No? Ok, well, if those were still here, this thing would be like 90239820 times smaller, cool huh? How many of those are we going to have to hear before we come up with some new kind of comparison. You know how fast a woman can plot a route around a detour using a map in a big city? Yeah? Well, this shit is like 939203902093902093092093 times faster.
  • I'd love to know how they managed to scale up to 80way x86? IIRC anything passed 8way was diminishing returns?
  • With high end processor power consumption approaching the better part of a kilowatt, perhaps toasting speed could be a measure.
  • Of course we won't see an 80-core processor any day soon! Intel will produce "new chips" every couple years and just add cores. I suspect they have done this all along (e.g, the Pentium series). That is it makes sense from a capitalist standpoint to throttle your technology to generate or maintain a certain level of demand. I have no evidence for this, but as cynical as it sounds it sure makes sense.

      They would release it right now if they could. You only need to throttle when there is an end game, and you don't have competition.

      The issue is the fab and the die. How many bad die's did they go through to get to this prototype? I would wager they had many more bad dies then good ones.

  • ought to be enough for anybody.

    Seriously, why don't we put the cores into the memory DIMMs? It's been tried before but now it seems that a CPU core is just a little commodity thing, and memory bandwidth is where the bottleneck is.

  • At 3.16GHz and with 0.95 volts applied to the processor, it can hit 1 teraflop of performance while consuming 62 watts of power.

    Yikes, that's over 65 amps! Well, OK, it's less than 1 amp per core.

  • Nobody believed me when I mentioned in a previous story comment that I was playing with an 8-core HP test system. Everyone went "No Wai!" and this was about three months or so ago. Lookie here - 80 fucking cores.

    Guess who's laughing now?
