N-body codes for performing simulations of the origin and evolution of the largescale structure of the universe have improved significantly over the past decade in terms of both the resolution achieved and the reduction of the CPU time. However, state-of-the-art N-body codes hardly allow one to deal

β¦ Synopsis
Sequential (\mathrm{N})-body codes have been in existence for many years. This paper shows how their algorithms may be adapted to produce an N.body code to run on a paraliel machine and describes the implementation of such a code upon the EdinburglΔ± Concurrent Supercomputer. The performance of the final program is analyzed, and an appendix discusses the optimal choice of the order of the integrator. 'C) 1994 Academic Press, Inc.

In recent years several implementations of molecular dynamics Ε½ . Ε½ . MD codes have been reported on multiple instruction multiple data MIMD machines. However, very few implementations of MD codes on single instruction Ε½ . multiple data SIMD machines have been reported. The difficulty in using pair
A parallel computational code for the numerical integration of the NavierΒ±Stokes equations has been developed. The system of partial dierential equations describing the non-steady Β―ow of a viscous incompressible Β―uid in three dimensions is considered and applied to the channel Β―ow problem. A mixed s
The paper shows the implementation of a 3D simulation code for turbulent flow and combustion processes in full-scale utility boilers on an Intel Paragon XP/S computer. For the portable parallelization, an explicit approach is chosen using a domain decomposition method for the static subdivision of t
