This work presents a parallel numerical strategy to transport Lagrangian particles in fluid using dynamic load balance strategy. Both and particle solvers are parallel, with two levels of parallelism. The first level is based on substructuring technique uses message passing interface (MPI) as the communication library; second consists OpenMP pragmas for loop parallelisation at node level. When dealing transient flows, there exist main alternatives address coupling these solvers. On one hand,...
The fluid-structure interaction (FSI) problem has received great attention in the last few years, mainly because it is present many physical systems, industrial applications, and almost every biological system. In parallel computational field, outstanding advances have been achieved for individual components of problem, allowing, instance, simulations around complex geometries at very high Reynolds numbers or contraction a beating heart. However, not an easy task to combine both fields,...
The main computing phases of numerical methods for solving partial differential equations are the algebraic system assembly and iterative solver. This work focuses on first task, in context a hybrid MPI+X paradigm. matrix consists loop over elements, faces, edges or nodes MPI partitions to compute element matrices vectors then their assemblies. In parallelism context, X has consisted traditionally using OpenMP, with different techniques avoid race condition, but presenting efficiency...
Alya is the BSC in-house HPC-based multi-physics simulation code. It designed from scratch to run efficiently in parallel supercomputers, solving coupled problems. The target domain engineering, with all its particular features: complex geome- tries and unstructured meshes, exotic coupling schemes Physical models, ill-posed problems, flexibility needs for rapidly including new etc. Since conception 2004, has shown scaling behaviour an increasing number of cores. In this paper, we present...
The urban and territorial changes caused by tourism are well-studied topics in contemporary scientific literature. This article uses an integrative approach that lies between the traditions geography of to present a case study socialist city. Tourism is strategic economic activity Cuba, country’s most popular sun sand tourist destination Varadero. At first consideration, its model not very different from those other areas region (Dominican Republic, Riviera Maya, etc.), but uniqueness Cuban...
We designed and implemented a parallel visualisation system for the analysis of large scale time-dependent particle type data. The particular challenge we address is how to analyse high perfor- mance computation style dataset when visual representation full set not possible or useful, one only interested in finding inspecting smaller subsets that fulfil certain complex criteria. used Paraview as user interface, which familiar tool many HPC users, runs parallel, can be conveniently extended....
El factor determinante para la producción de casos tuberculosis por transmisión exógena es existencia pacientes con baciloscopias positivas. objetivo este estudio fue determinar los factores riesgo asociados a microscopía positiva en secreciones respiratorias. Se estudiaron incidentes del período 1992–1998 provincia Lleida. Las variables fueron: edad, sexo, infección el VIH, uso drogas vía parenteral (UDVP), consumo alcohol, cavernas y resultado microcopia esputo. calculó tasa incidencia...
Large scale time-dependent particle simulations can generate massive amounts of data, making it so that storing the results is often slowest phase and primary time bottleneck simulation. Furthermore, analysing this amount data with traditional tools has become increasingly challenging, virtually impossible to have a visual representation full set. We propose novel architecture integrates an HPC-based multi-physics simulation code, NoSQL database, analysis visualisation application. The goals...
