In this work, we present a tool that exploits heterogeneous computing to calculate the noise scattered by an object from the pressure distribution over its surface and its normal derivative. The method mainly deals with a large Matrix–Vector Product where the matrix elements must be calculated on the fly in such a way that the problem fits in main memory.(More)
NnmfPack is a library for the nonnegative matrix factorization (NNMF) problem. Nowadays NNMF is an essential tool in many fields spanning machine learning, data analysis, image analysis or audio source separation, among others. NnmfPack is an efficient numerical library conceived for shared memory heterogeneous parallel systems, and it supports, from its(More)
