Value Creation

These technologies led to the realization of the K computer and Fugaku, which both took the top positions in renowned benchmark rankings. The K computer was the first to ever top each of the TOP500, HPCG, and Graph500 rankings. Fugaku also ranked first in the world for the newly established HPL-AI benchmark (now HPL-MxP), becoming the first supercomputer ever to top 4 rankings. In addition to the contributions of the K computer and Fugaku to society and scientific technology, they also contributed to improved brand awareness as the symbol of Fujitsu's technical prowess.
