A parallel, portable and versatile treecode.
Michael S. Warren, John K. Salmon · University of North Texas Digital Library (University of North Texas) · 1995
Portability and versatility are important characteristics of a computer program which is meant to be generally useful. We describe how we have developed a parallel N-body treecode to meet these goals. A variety of applications to which the code can be applied are mentioned. Performance of the program is also measured on several machines. A 512 processor Intel Paragon can solve for the forces on 10 million gravitationally interacting particles to 0.5% rms accuracy in 28.6 seconds.
