back to article Commercial spinoffs of Fujitsu's Post-K super 'puter will hit shelves long before exascale daddy switched on

Folk wanting in on the Arm-based goodness baked into Japan's upcoming "Post-K" exascale supercomputer are in luck – Fujitsu has finished the design and sales of commercial versions will begin some time between October 2019 and March 2020. The $910m Post-K will become the country's most powerful machine once it is switched on …

    FYI - the supported languages are FORTRAN, C and C++.

    Value for money?

    So its 910 Million for this computing power.

    That could buy an awful lot of lesser computers

    Obviously I know lots of things are massively computationally expensive (e.g. weather forecasts)

    But was just wondering if this is (currently) good value (compared to other mega machines or even as a silly stat how pricey is it per flop compared to a bog standard PC or mobile), or if its just a pricey proof of concept and commercial models will be better value

      Re: Value for money?

      It is good value. The cost per core is not really important, it's the interconnect (Tofu) that makes using those cores in big science applications fast.

      With that, the peak:average performance ratio across a range of application types is close to 1:1. With just a large number of ordinary computers on an Ethernet, this ratio would be much, much lower for most tasks.

      Tofu is completely mind bending (6 dimensional hypertoroid mixed up with a 4 dimensional hypercube), and they build it into the CPUs for the full effect of ultra - low latencies. A lot of other machines use infiniband, I think using PCIe NICs, which is fast but I don't think it's as good as Tofu.

      The predecessor machine, K, was notable in this regard, meaning that it's benchmark figures were very good and very translatable into application performance.

    But can you imagine a Beowulf cluster of these running Crysis?

    Besides the new flagship, the company is considering a cheaper "entry-level model" – and said this could be built by a third party.

    "Arm's successful collaboration with Fujitsu and Riken underscores our commitment to the HPC ecosystem," said Brent Gorda, senior director of HPC at Arm.

    The Post-K project (since it follows the "K" supercomputer)

    Surely that'd be "L" supercomputer.

      I bet one of those could be L to programme

    Dreaming is easy

    Over paper desing all works, reality is other thing. From mine point of view the heart stuff is efficiency, othertwise wil be faulty tech.
