abstract = {The simulation of hydrodynamic properties of fluid and flow
phenomena on the mesoscale is a challenge for conventional
techniques, e. g. Molecular Dynamics or Monte Carlo. In many
cases, the mesoscopic behavior of fluids or flows is
important to understand as it is key to the interplay
between macroscopic flow and microstructures. To overcome
the wide range of length and time scales, several mesoscale
simulation techniques were developed. Their principle is to
coarse-grain irrelevant atomistic details while correctly
incorporating the essential physics and conservation laws.
One of these mesoscale simulation techniques is the so
called Stochastic Rotation Dynamics (SRD), which solves the
linearized Navier-Stokes equations by using a particle-based
approach. Since the requirement of high performance
computing and memory for computer simulations is growing,
hardware architecture determines the efficiency of a
simulation in terms of execution time. The Cell Broadband
Engine (Cell/BE) is a heterogeneous multicore processor and
has been designed to support a broad range of applications.
To simplify the enabling of applications on the Cell/BE,
high-level programming models were developed. One example is
the Cell Superscalar Framework (CellSs) which offers a
portable programming model to port, parallelize and tune
applications on Cell/BE. In the scope of this thesis, a
simulation program on the basis of the SRD algorithm is
developed which is able to model a variety of fluids with
different properties. Additionally, an algorithm for the
simulation of immiscible binary mixtures is implemented,
which is applied in addition to the SRD algorithm.
Thereafter, the implementation is ported to the Cell/BE
using the high-level programming model CellSs. Finally,
simulation results using SRD are presented and the
performance results obtained by the calculation on the
Cell/BE are discussed critically.},
