MAPPRAISER: A massively parallel map-making framework for multi-kilo pixel CMB experiments
Hamza El Bouhargani, Aygul Jamal, Dominic Beck +3
Forthcoming cosmic microwave background (CMB) polarized anisotropy experiments have the potential to revolutionize our understanding of the Universe and fundamental physics. The so…
Solving linear equations with messenger-field and conjugate gradients techniques - an application to CMB data analysis
J. Papez, L. Grigori, R. Stompor
We discuss linear system solvers invoking a messenger-field and compare them with (preconditioned) conjugate gradients approaches. We show that the messenger-field techniques corre…
Accelerating Cosmic Microwave Background map-making procedure through preconditioning
Mikolaj Szydlarski, Laura Grigori, Radek Stompor
Estimation of the sky signal from sequences of time ordered data is one of the key steps in Cosmic Microwave Background (CMB) data analysis, commonly referred to as the map-making…
