    The post-K prototype will be exhibited at ISC 2018, which will be held in Germany from June 24--28.

    (48 + 2) or (48 + 4) cores per node, built on top of ARMv8 ISA plus SVE extensions (implemented with 512bit wide vectors).

    I guess the new ARM-based chip will look very much as the former SPARC-based supercomputer (32+2) chip

    What would be the TDP on a little beast like that?

    The merit isn't mine, but of one of guys that I follow on twitter, who found the document.

    I like that it is ARMv8 plus SVE, but I like still more it is entirely CPU based. GPUs aren't needed when you have a well-designed CPU.

    Moreover, the original K computer and successors are designed with real-workloads in mind. Unlike other supercomputers which get higher scores on toy-like benches, but then suffer with real-life code.
