An efficient and scalable block parallel algorithm of Neville elimination as a tool for the CMB maps problem

Alonso, P.; Cortina, R.; Ranilla, J.; Vidal Maciá, Antonio Manuel (Springer Verlag (Germany), 2012-02)

Abstract This paper analyses the performance of several versions of a block parallel algorithm in order to apply Neville elimination in a distributed memory parallel computer. Neville elimination is a procedure to transform ...
Detecting point sources in CMB maps using an efficient parallel algorithm

Alonso, P.; Argüeso, F.; Cortina, R.; Ranilla, J.; Vidal Maciá, Antonio Manuel (Springer Verlag (Germany), 2012-02)

The Cosmic Microwave Background (CMB) is a diffuse radiation which is contaminated by the radiation emitted by point sources. The precise knowledge of CMB fluctuations can lead to a better knowledge of the chemistry at the ...
Non-linear parallel solver for detecting point sources in CMB maps using Bayesian techniques

Alonso, P.; Argüeso, F.; Cortina, R.; Ranilla, J.; Vidal Maciá, Antonio Manuel (Springer Verlag (Germany), 2013-04)

Abstract In this work we present a suitable computational tool to deal with large matrices and solve systems of non-linear equations. This technique is applied to a very interesting problem: the detection and flux ...
