In this paper, we describe a new source code transformation called dynamic loop reversal that can increase temporal and spatial locality. We also describe a formal method for predicting the cache behaviour and evaluation results of the accuracy of the model by measurements on a cache monitor. The comparisons of the numbers of measured cache misses and the numbers of cache misses estimated by the model...
The paper considers application of the AVX (Advanced Vector Extensions) technique to improve the performance of the PARFES parallel finite element solver, intended for finite element analysis of large-scale problems of structural and solid mechanics using multi-core computers. The basis for this paper was the fact that the dgemm matrix multiplication procedure implemented in the Intel MKL (Math Kernel...
When there is a need to store a sparse matrix into a file system, is it worth to convert it first into some space-efficient storage format? This paper tries to answer such question for the adaptive-blocking hierarchical storage format (ABHSF), provided that the matrix is present in memory either in the coordinate (COO) or in the compressed sparse row (CSR) storage format. The conversion algorithms...
In this paper we describe a parallel implicit method based on radial basis functions (RBF) for surface reconstruction. Practical applicability of RBF methods is hindered by their high computational demand, that requires the solution of linear systems of size equal to the number of data points. The implementation of our method relies on parallel scientific libraries and is designed for exploiting Graphic...
