Composition of MDM Molecular Dynamics Machine (MDM) is a special-purpose computer for large scale molecular dynamics (MD) simulations. It has a peak speed of 78 Tflops. It is composed of two special-purpose computers, MDGRAPE-2 and WINE-2, and a host computer. MDGRAPE-2 performs real-space part of the Ewald summation and van der Waals calculation. WINE-2 performs wavenumber-space part of the Ewald summation. The host computer performs other operations, such as bonding force calculation, time integration and file I/O.
The following slides show the brief description of each part of the hardware.
