In this deck, Numascale describes how the company achieved a world-record on the McCalpin STREAM benchmark using their innovative scale-out to scale-up architecture. The benchmark measures sustainable memory bandwidth and the corresponding computation rate for simple vector kernels. Numascale’s cache coherent shared memory system, which was targeted for big data analytics, reached 10.06 TBytes/second for the Scale function. This feat ranked 53% higher than the next most scalable system on the list, which was only able to achieve 6.59 TBytes/second.
