ACCELERATION OF VORTEX METHODS CALCULATION USING MDGRAPE-2 AND MDGRAPE-3: A COMPARATIVE STUDY
Sheel, Tarun Kumar
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.
