TOKYO >> Fujitsu has unveiled a prototype of a next-generation supercomputer dubbed “post-K.” The machine is expected to calculate 100 times faster than the K supercomputer, which is operating in Kobe.

The firm unveiled a central processing unit (CPU), the computer’s brain, and other computer components.

Fujitsu said it would start producing the computer by September.

The post-K is being jointly developed by ­Fujitsu, the Education, Culture, Sports, Science and Technology Ministry and the research center Riken.

With world-class calculation speeds and energy-saving performance, the advanced computer is expected to be useful in fields such as medicine, disaster prevention and industrial technology.
