Fugaku prototype named greenest supercomputer!

The prototype for Fugaku, which is currently being developed by RIKEN and Fujitsu as a successor to the K computer, has been awarded the top spot on the Green 500 list, indicating that it is the most energy efficient computer on the list of the world’s 500 fastest computers measured on the LINPACK benchmark. The new ranking was announced on November 18 at the international supercomputing conference (SC19) in Denver, Colorado, and the awards ceremony was held on November 19.

With Fugaku, we succeeded in developing a general-purpose Arm CPU with the world's highest energy efficiency, far exceeding our targets through Co-design. While GPU machines dominate high ranks, it is groundbreaking for general-purpose CPU machines to top the list.

By becoming a new standard, general-purpose CPUs with different levels of energy efficiency are expected not only to generate revolutionary HPC results, but also to be applied to new technologies such as AI (artificial intelligence) and big data, which will realize Society 5.0.
