Supermicro has released two systems featuring Intel’s many-core Xeon Phi x200 processors: a workstation and an ultra-dense server. The platforms support up to 384 GB of DDR4 memory and are based on the good-old Intel C612 PCH. Due to high TDP of Intel’s Knights Landing CPUs, Supermicro had to use a custom closed-loop liquid cooling for its SuperWorkstation SYS-5038K-i.

Intel officially launched its Xeon Phi x200 many-core Knights Landing platform in June, but the company disclosed most of the details regarding its new processors last year at Supercomputing15. As discussed, every Xeon Phi x200 in LGA packaging has up to 72 cores (based on highly-modified Atom Silvermont microarchitecture) running at up to 1.5 GHz, with up to 36 MB of L2 cache, 16 GB of on-package high-performance memory (MCDRAM), six-channel DDR4 DRAM controller as well as 36 PCIe 3.0 lanes. The Xeon Phi x200 chips in LGA3647 form-factor can run as a host, directly with an operating system on board (including Windows Server 2016) which is an upgrade over the older Xeon Phi parts which only ran as co-processors on the PCIe bus. Moreover, the internal PCIe 3.0 root complex gives the Xeon Phi some PCIe lanes to allow other coprocessors to be plugged in - either additional Xeon Phi accelerators in the card form-factor, or AMD/NVIDIA cards, to maximize the compute horsepower.
