Cheap Supercomputers: LANL has 750-node Raspberry Pi Development Clusters

One of the more esoteric announcements to come out of SuperComputing 17, an annual conference on high-performance computing, is that one of the largest US scientific institutions is investing in Raspberry Pi-based clusters to aid in development work. The Los Alamos National Laboratory's [LANL] High Performance Computing Division now has access to 750-node Raspberry Pi clusters as part of the first step towards a development program to assist in programming much larger machines.

The platform at LANL leverages a modular cluster design from BitScope Designs, with five rack-mount Bitscope Cluster Modules, each with 150 Raspberry Pi boards with integrated network switches. With each of the 750 chips packing four cores, it offers a 3000-core highly parallelizable platform that emulates an ARM-based supercomputer, allowing researchers to test development code without requiring a power-hungry machine at significant cost to the taxpayer. The full 750-node cluster, running 2-3 W per processor, runs at 1000W idle, 3000W at typical and 4000W at peak (with the switches) and is substantially cheaper, if also computationally a lot slower. After development using the Pi clusters, frameworks can then be ported to the larger scale supercomputers available at LANL, such as Trinity and Crossroads.

    Just think. If you had an account, you could put that in a journal.

    A hat tip to hot grits.

    When I read Natalie Portman and Slashdot refugees I started imagining Beowulf has something to do with this cluster. That twitch has started up again....

    The announcement is date 7 nov.
    Which means the award has been given likely the 6 nov. Not the remember remember fifth of november, by one friggin day.

    Is this the way to say thanks for the V for vendetta depicting of high ranking prelates? Very disappointing.
