"Intrepid" Supercomputer Fastest In the World

Posted by CmdrTaco on Thursday June 19, @12:00PM
from the bravely-and-quickly dept.
Stony Stevenson writes "The US Department of Energy's (DoE) high performance computing system is now the fastest supercomputer in the world for open science, according to the Top 500 list of the world's fastest computers. The list was announced this week during the International Supercomputing Conference in Dresden, Germany. IBM's Blue Gene/P, known as 'Intrepid,' is located at the Argonne Leadership Computing Facility and is also ranked third fastest overall. The supercomputer has a peak performance of 557 teraflops and achieved a speed of 450.3 teraflops on the Linpack application used to measure speed for the Top 500 rankings. According to the list, 74.8 percent of the world's supercomputers (some 374 systems) use Intel processors, a rise of 4 percent in six months. This represents the biggest slice of the supercomputer cake for the firm ever."

  • ... will it run Vista with everything on?
  • Apparently, not necessarily. [netlib.org] It's just some Fortran routines.

    So much for that joke.

    This is the first time a system on the TOP500 has passed the Petaflop mark.

      Or 0.557 petaflops, but who's counting?

    Computer scientists building the monstrosity admit that it still isn't powerful enough to run VISTA with all the bells and whistles turned on.

    George Broussard says that when the next generation of this machine reaches the desktop, Duke Nukem 4ever will be released. "Really", he said, "The game's been finished for over five years now. We're just waiting for a powerful enough computer to play it on."

    Sources say that besides computitng power, DNF is waiting for the holographic display. The The US Department of Energy's (DoE) high performance computing system lacks a holographic display.

    Gamers were reportedly disappointed in the news, although most said the price of the DoE's new computer wouldn't faze them. "After all" one said, "you have to have a decent machine to play any modern game!"

    The title says: "'Intrepid' Supercomputer Fastest In the World" for open science while the article says "IBM's Blue Gene/P, known as 'Intrepid', is located at the Argonne Leadership Computing Facility and is also ranked third fastest overall." There needs to be some clarification. Roadrunner [networkworld.com] is considered the fastest in the world and is also built for the DOE. I'm guessing that Roadrunner is used exclusively by Los Alamos and is not available for open science while Intrepid is.

    Top500 [top500.org] has the actual list. Would have been nice to have this in TFA or TFS.
  • I liked (back in the Old Days) when supercomputer rankings where based on linear, single processor performance. Now it's just how much money can you afford to put a lot of processors in a single place. That was a real test of engineering. By the current standards, Google (probably) has the largest supercomputer in the world.

    Unfortunately, single core performance seems to have hit the wall.

      Even in the Old Days, supercomputers had multiple processors.

      --
      In 1988, Cray Research introduced the Cray Y-MP®, the world's first supercomputer to sustain over 1 gigaflop on many applications. Multiple 333 MFLOPS processors powered the system to a record sustained speed of 2.3 gigaflops. --
      The difference today is that almost all supercomputers use commodity chips, instead of custom designed cores.

      Ohh - and the IBM one is almost a million times faster than the 20 years old '88 cray model.

    • That was a real test of engineering. By the current standards, Google (probably) has the largest supercomputer in the world.

      Sorry, but no. As big as one of Google's several data centers might be, it can't touch one of these guys for computational power, memory or communications bandwidth, and it's darn near useless for the kind of computing that needs strong floating point (including double precision) everywhere. In fact, I'd say that Google's systems are targeted to an even narrower problem domain than Roadrunner or Intrepid or Ranger. It's good at what it does, and what it does is very important commercially, but that doesn't earn it a space on this list.

      More generally, the "real tests of engineering" are still there. What has changed is that the scaling is now horizontal instead of vertical, and the burden for making whole systems has shifted more to the customer. It used to be that vendors were charged with making CPUs and shared-memory systems that ran fast, and delivering the result as a finished product. Beowulf and Red Storm and others changed all that. People stopped making monolithic systems because they became so expensive that it was infeasible to build them on the same scales already being reached by clusters (or "massively parallel systems" if you prefer). Now the vendors are charged with making fast building blocks and non-shared-memory interconnects, and customers take more responsibility for assembling the parts into finished systems. That's actually more difficult overall. You think building a thousand-node (let alone 100K-node) cluster is easy? Try it, noob. Besides the technical challenge of putting together the pieces without creating bottlenecks, there's the logistical problem of multiple-vendor compatibility (or lack thereof), and then how do you program it to do what you need? It turns out that the programming models and tools that make it possible to write and debug programs that run on systems this large run almost as well on a decently engineered cluster as they would on a UMA machine - for a tiny fraction of the cost.

      Economics is part of engineering, and if you don't understand or don't accept that then you're no engineer. A system too expensive to build or maintain is not a solution, and the engineer who remains tied to it has failed. It's cost and time to solution that matter, not the speed of individual components. Single-core performance was always destined to hit a wall, we've known that since the early RISC days, and using lots of processors has been the real engineering challenge for two decades now.

      Disclosure: I work for SiCortex, which makes machines of this type (although they're probably closer to the single-system model than just about anything they compete with). Try not to reverse cause and effect between my statements and my choice of employer.

    The PS3's RSX video chip [wikipedia.org] from nVidia does 1.8TFLOPS on specialized graphics instructions. If you're rendering, you get close to that performance. The PS3's CPU, the Cell [wikipedia.org], gets theoretical 204GFLOPS on its more general purpose (than the RSX) onchip DSP-type SPEs, and some more on its onchip 3.4GHz PPC. A higher end Cell with 8 (instead of 7 - less one for "chip utilities" - in the PS3's Cell) delivers about 100GFLOPS on Linpack 4096x4096. Overall a PS3 has about 2TFLOPS, so 278 PS3s have a theoretical peak equal to this supercomputer. But they'd cost only $11,200. YMMV.

      The top500 list [top500.org] clearly show that roadrunner is #1. What's this one then?
      I'll let TFA answer this one:

      IBM's Blue Gene/P, known as 'Intrepid', is located at the Argonne Leadership Computing Facility and is also ranked third fastest overall.
      In other words I don't really know why this is news. I don't think anything has changed about its position recently (other than Roadrunner becoming #1 a few weeks back).
