    Default Parallella: Low-Cost Linux Multi-Core Computing

    Phoronix: Parallella: Low-Cost Linux Multi-Core Computing

    Parallella is an attempt to make Linux parallel computing easier and is advertised as a "supercomputer for everyone", but will it come to fruition?..

    Sounds very interesting. I'd really like to try this as my NAS server which will also transcode some videos

    Thanks for the heads up.

    Default You keep using that word...

    Yeah... "Expected to be on the Parallella computer is a Zynq-7010 Dual-core ARM A9 CPU, an Epiphany Multi-core Accelerator, 1GB of RAM, USB 2.0 support, Gigabit Ethernet,"

    Supercomputing... you keep using that word. I do not think it means what you think it means.

    It is certainly a moving target. I remember Apple marketing some PowerPC computers with the term as well, but likely the best comparison we can bring up is in flops/W to actual current day supercomputers. Those seem to hover about 2.1Gflops/W (and that model is #1 of top500 as well). The Epiphany IV 64-core processor is advertised as 100Gflops (peak) with 2W power consumption (max), placing it at nearly 50Gflops/W; but obviously you need a power supply, memory and so on, so it's more appropriate to check the whole board. That has a quoted typical consumption of 5W, so if we bump that up by 2W, and then factor in a pessimistic 80% efficient power supply, we get 11.4Gflops/W. It's certainly in the ballpark, though you'd need thousands of them to make a true supercomputer. The base model (16 cores) has the same power consumption, so just divide by 4.

    Communication overhead will swallow all the advantages.

    I prefer GPU or Intel MIC, even for personal usage.

    SGI Onyx was sold as a "supercomputer"

    The promotional materials still exist

    Does that mean it's not a "supercomputer" today? When did the promotional materials pass from truth to non-truth?

    Today any android device will blow its doors off

    YOU are the one who thinks "Supercomputer" has some magical mysterious meaning that you apparently refuse to share with the rest of us.

    Or perhaps you are the ultimate arbitrator of the english language and you are here to correct all our speling errors and grammar misteaks.

    I imagine the readers here will like the detailed reference manuals.

    There is also this which is a bit lighter to read http://www.adapteva.com/news/adaptev...ps-less-watts/

    Anyone tested galium3d on that thing?

    According to Adapteva board doesn't have GPU.
