The objective of this work is to improve the performance of Monte Carlo codes on Grid production infrastructures. To do so, the codes and the grid sites are characterized with simple parameters to model their behaviors. Then, a new performance model for grid infrastructures is proposed, and an algorithm that employs this information is described. This(More)
Calculating neoclassical (NC) transport is a fundamental part of the complete simulation cycle of the behavior of plasmas inside all tokamaks and stellerators. Also, due to NC transport is mainly determined by the magnetic properties of the device, its study is mandatory to ensure the efficiency of a certain coil configuration before it is implemented in a(More)
ISDEP (Integrator of Stochastic Differential Equations for Plasmas) is a Monte Carlo code that solves the plasma dynamics in a fusion device and perfectly scales on distributed computing platforms. Montera is a recent framework developed for achieving Grid efficient executions of Monte Carlo applications, as ISDEP is. In this work, the improvement of(More)
This work determines the molecular epidemiology of dengue virus in Venezuela by means of phylogenetic calculations performed on the EELA-2 Grid infrastructure with the PhyloGrid application, an open source tool that allows users performing phylogeny reconstruction in their research. In this study, a total of 132 E nucleotide gene sequences of dengue virus(More)
jModelTest is a Java program for the statistical selection of models of nucleotide substitution with thousands of users around the world. For large data sets, the calculations carried out by this program can be too expensive for many users. Here we describe the port of the jModeltest code for Grid computing using DRMAA. This work should facilitate the use(More)
The execution of data-based applications on distributed environments is prone to different failures in the different steps of the process. These steps range from the search on available references and data to the adaptation of the applications of interest to the different platforms where they are going to be efficiently run, which requires a deep(More)
FAFNER2 is a 3D code that simulates by Monte Carlo methods the Neutral Beam Injection (NBI) technology. The original version was implemented for shared memory computers with MIPS proccesors, so an update to be executed by means of MPI on standard Linux clusters has been carried out as well as a new version to be run on Grid. To do the latest, a serial(More)
The gyrofluid electromagnetic (GEM) model studies the phenomena in the context of edge turbulence, a matter of adding collisions and electromagnetic induction to the parallel dynamics of the standard six-moment toroidal model, the use of which was done in core turbulence works. Currently, the code describes the fluctuation free-energy conservation in a(More)
High Performance Computing (HPC) resources have become the key actor for achieving more ambitious challenges in many disciplines. In this step beyond, an explosion on the available parallelism and the use of special purpose processors are crucial. With such a goal, the HPC4E project applies new exascale HPC techniques to energy industry simulations,(More)
Nowadays, computing calculations are becoming more and more demanding due to the huge pool of resources available. This demand must be satisfied in terms of computational efficiency and resilience, which is compromised in distributed and heterogeneous platforms. Not only this, data obtained are often either reused by other researchers or recalculated. In(More)
