From the summary: We report on the results of a joint effort of astrophysicists and computer scientists to develop and implement a parallel program that enables us to solve large systems of hydrodynamic equations, and covers a wide range of applications in astrophysics. We introduce the distributed threads system (DTS) as an environment for the development of portable parallel applications. The numerical method smoothed particle hydrodynamics (SPH) is used to simulate the viscous spreading of an accretion disk around a massive compact object as an astrophysical test problem. The SPH code was parallelized using DTS and successfully ported to systems of different architecture.
