Abstract
The calculation of vortex method has been
accelerated by using special-purpose computers,
MDGRAPE-2 and MDGRAPE-3, respectively. The
similar algorithm has been implemented and the
improvement in speed of MDGRAPE-2 was 100
times while MDGRAPE-3 was 1000 times faster
when compared with the ordinary PC Xeon
5160(3.0GHz) for N=106. In addition, the speed of
MDGRAPE-3 was 25 times faster compared with
MDGRAPE-2. The round off errors have been
investigated in both cases.
