Journal ArticleDOI
A reconfigurable systolic torus for iterative matrix operations
TL;DR: Recursive equations, frequently met in a wide range of problems, can be solved through a new systolic structure, the Reconfigurable Systolic Torus, in almost optimal Area and Time requirements.
Journal ArticleDOI
Computing dot -- product on heterogeneous master -- worker platforms
TL;DR: The obtained experimental results demonstrate that the dynamic allocation of vector point- ers achieve better performance than the original one for computing dot product computation.
A parallel memetic library for optimization problems
TL;DR: This work presents PARA.MENOAS, an object - oriented memetic algorithms library based on C++ and using the MPI message passing interface that provides an automatic, transparent way of parallelizingmemetic algorithms.
Journal ArticleDOI
Large Scale Modelling Of Two-dimensional Cardiac Tissue Using Parallel Methods

TL;DR: The number of iterations needed for convergence of the iterative methods at each time step is examined in conjunction with changes in the spatial distribution of the electrophysiologic parameters such as coupling resistance.
Book ChapterDOI
Performance analysis of approximate string searching implementations for heterogeneous computing platform
TL;DR: An analytical performance prediction model is presented that can be used to predict the execution time, speedup and similar performance metrics of four approximate string searching implementations running on an MPI cluster of heterogeneous workstations.
