#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.
