MDGRAPE-3 is an ultra-high performance petascale supercomputer system developed by the RIKEN research institute in Japan. It is a special purpose system built for molecular dynamics simulations, especially protein structure prediction. MDGRAPE-3 consists of 201 units of 24 custom MDGRAPE-3 chips (4824 total), plus additional dual-core Intel Xeon processors (codename "Dempsey") which serve as host machines. In June 2006 RIKEN announced its completion,〔RIKEN press release, ''(Completion of a one-petaflops computer system for simulation of molecular dynamics )''〕 achieving the petaFLOPS level of floating point arithmetic performance.〔 This was more than three times faster than the 2006 version of the IBM Blue Gene/L system, which then led the TOP500 list of supercomputers at 0.28 petaFLOPS. Because it's not a general-purpose machine capable of running the LINPACK benchmark, MDGRAPE-3 does not qualify for the TOP500 list. ==See also== * Supercomputing in Japan * MDGRAPE-4 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RIKEN MDGRAPE-3」の詳細全文を読む スポンサード リンク
