φ is a Linux cluster system with the 171 nodes interconnected with high speed network InfiniBand. A part of the nodes are loaded with GPGPU accelerators. The theoretical peak performance of the whole system achieved 62TFlops, which makes this system one of the fastest computers installed in the central Japan area.
This computer system is named φ taking the initial letter of the Greek words: the name of our prefecture "Aichi": φιλoσoφια, "Physics": φυσικoζ, the complex phase "φ" as a symbol of the Kobayashi-Maskawa theory, and a letter in the signature that the director general Maskawa uses: τ . φκαωα. The plate engraved "φ" was put on the enclosure of the computer system by the director general Maskawa during the inauguration ceremony.
Utilizing φ, KMI is aiming to elucidate the origin of the mass in elementary particle physics from the dynamical mechanism. It is the first time in the world that a high performance computing system dedicated to the physics beyond the standard model was constructed. Through this it is anticipated that KMI will contribute to explore the new horizon of the modern physics beyond the standard model.
