calling for proposals for the name of the post-K

The RIKEN Center for Computational Science (R-CCS) is calling for proposals for the name of the successor to the K computer (often referred to as the post-K computer), which has been under development with the target to start providing shared use service around the year 2021.

The following should be considered when proposing names for the supercomputer.

  • The name should preferably express the idea that RIKEN is a world-class research institute operating a state-of-the–art supercomputer.
  • The name should be attractive not only to Japanese speakers but to people around the world.

Post-K Prototype

  • The post-K computer is expected to contribute to Japan’s growth and to produce world-leading results by exploring science and solving various societal issues that are becoming more complicated. It will be one of the world’s most advanced supercomputers in terms of computational performance, potential for producing epoch-making results, usability for users, and energy efficiency.
  • It will be used not only for computer simulations but also for cutting-edge research in artificial intelligence (deep learning) and Big Data.
  • The goal is to achieve the application performance up to 100 times that of the K computer.
  • It is equipped with the ARM instruction set, which is widely used in smart phones, etc. throughout the world. The post-K computer will push forward the field of semiconductor and IT technology in the world.
