context_page_description: The High Energy Accelerator Research Organization, known as KEK, is a Japanese organization whose purpose is to operate the largest particle physics laboratory in Japan, situated in Tsukuba, Ibaraki prefecture. It was established in 1997. The term "KEK" is also used to refer to the laboratory itself, which employs approximately 695 employees. KEK's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics, material science, structural biology, radiation science, computing science, nuclear transmutation and so on. Numerous experiments have been constructed at KEK by the internal and international collaborations that have made use of them. Makoto Kobayashi, emeritus professor at KEK, is known globally for his work on CP-violation, and was awarded the 2008 Nobel Prize in Physics.
context_section_description: KEK has computers which are fastest class in Japan, and Computing Research Center in KEK manages the computer systems. The theoretical operation performance of SR16000, a super computer made by HITACHI, is 46 TFLOPS. The theoretical operation performance of Blue Gene Solution, a super computer made by IBM, is 57.3 TFLOPS. These super computers had been used to study quantum chromodynamics and numerical accelerator physics mainly, and these super computers have been shut down in order to introduce a next super computer in the future. Computing Research Center also manages the other computer systems: KEKCC, B-factory Computer System and Synchrotron Light Computer System.
  KEK hosted the first web site in Japan on September 30, 1992. The original web site can still be seen.
