“…several simulation tools such as BrownDye [7] and the BROWNFLEX program included in the SIMUFLEX suite [5], and many other studies oriented to specific fields, such as DNA research [8] or copolymers [10]. Although most of these works focus on sequential codes, some of them have developed parallel implementations with OpenMP, applied to smoothed particle hydrodynamics (SPH) [6] and the transportation of particles in a fluid [16]. The UPC language has also been used in a few works related to particle simulations, such as the implementation of the particle-in-cell algorithm [12].…”

The simulation of particle dynamics is an essential method to analyze and predict the behavior of molecules in a given medium. This work presents the design and implementation of a parallel simulation of Brownian dynamics with hydrodynamic interactions for shared memory systems using two approaches: (1) OpenMP directives and (2) the Partitioned Global Address Space (PGAS) paradigm with the Unified Parallel C (UPC) language. The structure of the code is described, and different techniques for work distribution are analyzed in terms of efficiency, in order to select the most suitable strategy for each part of the simulation. Additionally, performance results have been collected from two representative NUMA systems, and they are studied and compared against the original sequential code.

Three-dimensional fluid mechanics and heat transfer for viscoplastic flows are described by FVM. The OpenMP approach has been implemented to parallelize the numerical code. Results for the elapsed times, speed-ups and efficiencies are presented. The code was used to describe the natural convection (Ra=104; 106) and the lid driven cavity (Re=100; 1000) processes with Bingham, Casson and Herschel-Bulkley fluids (Bn=0.01; 1.0). Results describing isotherms, velocity distributions and streamtraces, as a function of Ra, Re, Pr and Bn numbers are shown. The grid size analysis shows that different sizes are required to obtain precise results for Nusselt number and friction factor.
