MDGRAPE-3

from Wikipedia, the free encyclopedia

MDGRAPE-3 is a supercomputer that was designed by the Japanese research institute RIKEN for the purpose of molecular dynamics simulation , especially for the calculation of protein structures .

The computer 201 is composed of units each with 24 RIKEN MDGRAPE-3-chip and additional dual-core - Intel Xeon processors (code name "Dempsey") serving as the host machine.

In June 2006, RIKEN announced the completion of the system capable of performing one quadrillion floating point operations per second (1 petaflop / s). This is comparable to the speed of the IBM Roadrunner , which tops the TOP500 list of the fastest supercomputers from November 2008. Since MDGRAPE-3 is not a system for general calculations but processes special tasks, it could not qualify for the TOP500 list due to the incompatibility with LINPACK . This is why the system is often cited as an example of the negative aspects of LINPACK.
