  1. Lego case 64 Raspberry Pi Cluster by Roger+W+Moore · · Score: 1 · on GCHQ Builds a Raspberry Pi Super Computer Cluster

    The reinvented a wheel (a cluster)

    Actually they reinvented the wheel not just in the generic sense but also in the specific sense that someone else has already built a 64 node Raspberry Pi cluster...and instead of some custom designed case theirs used a home build lego case which was definitely cooler. Of course this should not be too surprising. It was made by GCHQ after all so they probably got the idea from reading this guy's email!

  2. Misleading FUD! by Client_Notes · · Score: 1 · on GCHQ Builds a Raspberry Pi Super Computer Cluster

    Dross and misleading article, states they couldn't disclose the source of how to build one, maybe because they stole it from a South Hampton University Professors original work and would rather you didnt build one putting there fail to shame on public record! See: http://www.southampton.ac.uk/~... Beowulf clusters are a dime a dozen and easy enough to do, GCHQ is certainly not the first person to think of it, nor is there HQ somewhere I would advocate my child should work. The USAF already did something similar with PS2's (Playstation's to build a giant cracking cluster and all it could break was Rainbow Tables!) and if you expect your children to have common sense then perhaps it's something that should be distilled into them at an early age, a bit like morals and why hacking into phone's and spying on people is morally wrong! On the other hand however, most hilarious to read about how there Allies and there SPY website got hacked with weak encryption by a load of very peeved off hackers with Freaky SSL though!

    You meant to say "Imagine a Beowulf cluster of these" didn't you?

    Beowolf - I've heard of that. I think that the poem, Beowolf, has an old vernacular. The computing concept, however - with the term, "cluster," appended - there is a Wikipedia page.[1] As far as clustering with RPi, there's the proof of concept work at the U. Southampton[2].

    Personally, I would inquire "MPICH or OpenMPI?" There is some proof of concept work towards the latter on RPi[3]. I'm not sure if it would be of a lot of use outside of C programs, but maybe.

    Of course, there would be the question, "What for?" I'm sure Open Science Grid might not be in the market for just any odd item of hacking stuff, for instance, they would certainly have all the resources they need for making predictive, if no pessimistic global climate change models. Personally I'm not sure if PVM would be used for much else, in computing. I'll just not comment about the big monolith of a building in DC, at that, LoL. (I'm not sure how Hadoop might factor onto parallel computing, after all)

    Maybe an RPi Compute Supercluster could be used for a bit of AI prototyping, with the old Common Lisp language and an Artificial Neural Network model, specifically after Adaptive Resonance Theory?

    In the hardware, I wonder, could a few RPi Compute Modules communicate via a serial protocol to a central chatterbox on a single Compute Supercluster board? The chatterbox, then, could communicate with a "master chatterbox" via PCI. Would that be too naive of a design, I wonder?

  4. Re:Nothing ever comes of these "child geniuses" by jonfr · · Score: 1 · on The Boy Genius of Ulan Bator

    You can only store data in 3 dimensions in quartz like materials. The problem is writing and reading and I just don't think the technical level is just there yet. They are now testing 5 dimensional storage. I am not sure how stable that is (due to quantum factors that is impossible to predict for) in the short and long run.

    I am sure they are going to work out the issues in the end. It might take 30 to 100 years until they do so. I am not up to speed on how the progress has been going in this research.

  5. Re:Backups? by Mostly+a+lurker · · Score: 1 · on Fire Destroys Southampton Fibre-Optics Center
    I know it can be very difficult for outsiders to understand how starved for cash English universities have been for over 20 years. My brother-in-law, as it happens, was on the Civil Engineering faculty at Southampton University through the 1980s and most of the 1990s, so I know the struggle there was for cash.

    I think the building in question is this one here, based on the BBC press report. Note that this is a virtual reality view, not a static image so you can pan the view and pan in and out. While hard to tell, I would guess this is an adapted 1970s era building.

    Actually he cheated. Only the HTML is being served off the grill. The images are being served from a box in Southampton University.
