Abstract

*Correspondence: James Lin, Center for HPC, Shanghai Jiao Tong University, Shanghai, China, james@sjtu.edu.cn Abstract The supercomputer π at Center for HPC (CHPC) of Shanghai Jiao Tong University (SJTU) was the fastest supercomputer among all the universities in China during 2013 to 2015. With a highly hybrid architecture, it is the first “CPU+GPU+MIC” supercomputer in China. It was also the largest Kepler GPU cluster in China when deployed in 2013. In addition, it firstly utilized the “FDR+DDN” combination in China. In this paper, we will introduce the design of supercomputer π.
