How To Build a Supercomputer In 24 Hours 161

Posted by timothy
from the foxconn-this-ain't dept.
An anonymous reader writes with a link to this "time lapse video of students and postdocs at the University of Zurich constructing the zBox4 supercomputer. The machine has a theoretical compute capacity of ~1% of the human brain and will be used for simulating the formation of stars, planets and galaxies." That rack has "3,072 2.2GHz Intel Xeon cores and over 12TB of RAM." Also notable: for once, several of the YouTube comments are worth reading for more details on the construction and specs.

      Build a computer in 24 hours? I guess it's possible.

      Fund its costs and gather the materials? I guess not.

      Not if you want to have a result in your lifetime. Cloud-based systems can be more powerful than your desktop, but are terribly slow compared to even an average supercomputer like this one (they are using ethernet cables for the interconnects...). The stuff you want to compute on these machines requires a high level of communication between the processes, else you would simply run them on several decoupled machines in parallel. You cannot access the required speed for inter-process communication on the clou

        Of course the cloud is not suitable for many applications, and it won't compete head-to-head with traditional supercomputers. But is does work for some applications. Least year a Pharmaceutical company used a 30,000 core system on AWS [wired.com] for a short period, and a company is already in business [cyclecomputing.com] that specializes in cloud supercomputing. I expect the capability will grow.

  • Knowing that the base assumptions can make this kind of silly estimate vary widely, I demand the methodology for this number! Once you take into account the frequency and even if you consider that a neuron is ~ 1000 transistors, such a machine easily outperforms the weak human with his 10 kHz (while being *very* nice toward humans) parallel machine.

      Yes indeed it's a ridiculous claim. If it has the computing power of 1% of the human brain, why even build it?

      Didn't you notice the modern miniaturized version of on board Beowulf cluster integrated in a chip chips they put it there? I would guess they put about 50 of them in the rack but since it was in fast forward, I couldn't count accurately. Anyway, if they build a Beowulf cluster of those, we will end up with a Beowulf cluster of Beowulf clusters.

    • by thegarbz (1787294)

      The risk of damage depends on the sensitivity of the component. For instance good luck wreaking a standard BJT with ESD. On many ICs the I/O is either suitably protected against ESD, or the nature of the design makes it less vulnerable to the effects of a sudden static spike.

      It's a very different story for say working with high frequency MOSFETs, uncut silicon wafers, or pretty much any RF gear. I remember in our lab one of the PHD students was working on a silicon wafer. The instrument had the wafer suspen

      we use various astrophysics simulation codes, i.e. GASOLINE, PKDGRAV, RAMSES etc. some are developed by us. they are all MPI and solve the coupled gravitational and hydrodynamic equations that can describe the dark matter and baryons evolving in the expanding universe. memory and speed of the computer limit the resolution that can be attained, so various "sub-grid" physical processes have to be treated carefully. for cosmological simulations we know the initial conditions - those are the fluctuations that we can read off the microwave background. they show the universe was hot, dense and smooth early on. the codes follow the perturbations into the non-linear regime when dark matter haloes, stars and galaxies form. we can then compare the properties of simulated structures with observational data etc.

    NO grounding straps.
    NO signs of any ESD precautions!!!

    Lacking from the video is the debugging process.

    Sure they built it in 2 days... but how many nodes came ready?

    I was cringing through the whole video over their lack of concern for basic ESD prevention. They don't need to be wearing bunny suits or anything that extreme, but FFS.... could ya show a little bit of respect for the hardware? Heck even clipping the freaking base-plates to ground during assembly would have been more than adequate.

    Used to do this kind of stuff when I was with IBM about 10 years ago, we had a group in XSeries Manufacturing who specialised in quick turnaround configuration of HPC rack systems just like this. Funnily enough, one of the major logistical elements was dunnage, ie the empty cardboard/foam and plastic that all the option parts arrive in. When running full out we used to have 1-2 guys per shift just to move the rubbish out to the big compactors out back. You wouldn't believe just how much packaging even a comparatively small cluster like that can generate.
  • I sometimes look at the ads for the local computer stores and add up what it would cost to roll my own cluster. At 2012 prices a 32 core cluster (say, 8 Core i5 CPUs) would cost only a little more than my first computer, that I bought in 1986. And that's at retail prices. I'm sure if I wanted a bulk purchase, the stores would cut me a deal.
