MDGRAPE-3 should not be confused with the astronomical supercomputer Grape [1].

MDGRAPE-3 is an ultra-high performance 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[1].

MDGRAPE-3 consists of 201 units of 24 custom MDGRAPE-3 chips (4808 total), plus 64 servers each with 256 Dual-Core Intel Xeon processors (codename "Dempsey"), and 37 servers each containing 74 Intel 3.2GHz Xeon processors, for a total of 40,314 processor cores.

In June 2006 RIKEN announced its completion, achieving the PetaFLOPS level of floating point arithmetic performance. This is about three times faster than the IBM BlueGene/L[2] system, which leads the TOP500 list of supercomputer performance as of 2006. Because it's not a general-purpose machine capable of running the LINPACK benchmark, MDGRAPE-3 does not qualify for the TOP500 list.
