Preferred Networks’ private supercomputer ranked first in the Japanese industrial supercomputers TOP 500 list


MN-1, a private supercomputer used exclusively by Preferred Networks, Inc. (PFN, Headquarters: Chiyoda-ku, Tokyo, President and CEO: Toru Nishikawa) has recorded a LINPACK  performance of about 1.39 PetaFLOPS 2.  As a result, MN-1 is ranked 12th in the world and 1st in Japan among industrial supercomputers in the TOP500 List (http://www.top500.org), which shows the most powerful supercomputers as of November 2017. When including supercomputers for research purposes, it is listed as 91st in the world and 13th in Japan.   



About PFN’s private supercomputer MN-1   

MN-1 is equipped with a Graphics Processing Unit (GPU) platform from NTT Communications Corporation (NTT Com, Headquarters: Chiyoda-ku, Tokyo, President and CEO: Tetsuya Shoji) and NTT PC Communications Incorporated (NTTPC, Headquarters: Minato-ku, Tokyo, President and CEO: Motoo Tanaka), and contains 1,024 of NVIDIA (R) ’s Tesla (R) multi-node P100 GPUs. It utilizes Mellanox’s Infiniband interconnect to make high-speed distributed deep learning possible using ChainerMN 4, a distributed deep learning package developed by PFN.    

Using MN-1, PFN will further accelerate its research and development activities in various fields that require a huge amount of computing resources such as transportation systems, manufacturing and bio/healthcare.




1.  A benchmark to compare practical operation speed of computers

2.  A unit measuring computer performance. Peta is 1,000 trillion (10 to the power of 15) and FLOPS is used to count floating-point operations per second. So, 1 PetaFLOPS means that a computer is capable of performing 1,000 trillion floating-point calculations per second.

3.  Preferred Networks launches one of Japan’s most powerful private sector supercomputers

4.  Preferred Networks achieved the world’s fastest training time in deep learning
