Dr. Takayuki Aoki of Tokyo Institute of Technology visited and spoke at the NCHC

【About TSUBAME】

It's a supercomputer in the Tokyo Institute of Technology, which jointle built it with Sun Microsystems Inc. and NEC Corporation. 

TSUBAME2.0 was built by NEC and HP. It was the first pentaflop mainframe in Japan. Its best ranking was 5th in the TOP500 in June 2011.

TSUBAME3.0 was ranked 22nd in TOP500 in November 2018, only two places behind Taiwania 2.
