HPE Announces World's Largest ARM-based Supercomputer (zdnet.com)

The race to exascale speed is getting a little more interesting with the introduction of HPE's Astra -- what will be the world's largest ARM-based supercomputer. From a report: HPE is building Astra for Sandia National Laboratories and the US Department of Energy's National Nuclear Security Administration (NNSA). The NNSA will use the supercomputer to run advanced modeling and simulation workloads for things like national security, energy, science and health care.

HPE is involved in building other ARM-based supercomputing installations, but when Astra is delivered later this year, "it will hands down be the world's largest ARM-based supercomputer ever built," Mike Vildibill, VP of Advanced Technologies Group at HPE, told ZDNet. The HPC system is comprised of 5,184 ARM-based processors -- the Thunder X2 processor, built by Cavium. Each processor has 28 cores and runs at 2 GHz. Astra will deliver over 2.3 theoretical peak petaflops of performance, which should put it well within the top 100 supercomputers ever built -- a milestone for an ARM-based machine, Vildibill said.

  1. Quantity game? by Tablizer · · Score: 1, Flamebait

    Maybe I'm naive, but a typical "supercomputer" these days mostly just connects up bunches of servers (or "servlets") via a central cluster manager or cluster tree. The "size" of the super-computer is then roughly the total number of CPU's (or maybe total instructions per second for the entire shebang).

    Thus, if you want to make a "numeric" world's record, you just get ship-loads of servers and hook them up to the cluster manager tree. It's mostly a quantity pissing match roughly comparable to having the tallest building.
