The latest revision of the rating of the world's 17 fastest supercomputers complexes used to accelerate calculations coprocessors Xeon Phi.  Characteristically, the fastest supercomputer - Chinese Tianhe-2 - with a capacity of more than 33 petaflops employs 48,000 accelerators Xeon Phi 31S1P, relating to the generation of Knights Corner. On passing  ISC conference in Leipzig in 2014, Intel announced a new generation of coprocessors - Knights Landing.  Peak performance of new accelerators three times higher than those in coprocessors Knights Corner (up to 61 core and 244 streams, 1.2 teraflops) and more than 3 teraflops of double precision, making them the most powerful Intel solutions for today. At the heart of Knights Landing lie computational core microarchitecture Silvermont, familiar from mobile platforms Bay Trail and Merrifield.  Cores are not specified, but, according to some information,   there are 72 pieces.  Interestingly, the boosters will use memory type Hybrid Memory Cube (HMC), the initial stages of its volume can reach 16 GB.  In Knights Landing applied interconnect technology Omni Scale Fabric, different from True Scale Knights Corner accelerators and based on InfiniBand. Knights Landing boosters can be performed both in the form of expansion cards PCI Express, in which case they play the role of accelerating computing coprocessor and a detachable CPU, installed directly into the motherboard and the ability to work independently. First supercomputer, which will be processors Knights Landing, will be Cori, which in 2016 will be deployed at the National Computing Centre for Energy Studies, owned by the Department of Energy.  Cori receive about 9300 accelerators that will surely allow it to enter the top ten ranking TOP500.
