KEK inaugurated the Large-scale Simulation Program in April 1996 in order to support large-scale simulations in high-energy physics and related fields. Under this program, KEK solicits proposals for projects that involve use of the KEK supercomputer.
From October 2009, the research period of the Large-scale Simulation Program was changed to one year from October to September of the following year. 25 proposals were approved by the Program Advisory Committee for the half-year research period from April to September 2010. These proposals were for the following research areas: lattice QCD (Quantum Chromodynamics) (11), elementary particle physics (2), nuclear physics (3), material science (3), astrophysics (2), accelerator science (3), and numerical algorithms & computational methods (1). 26 projects are underway for the research period from October 2009 to September 2010. The average usage of the supercomputer system (Hitachi SR11000 model K1 and IBM System Blue Gene Solution) was consistently high at 95%, operating 24 hours a day for 356 days.
