The fast and accurate solution of large size sparse systems of linear equations is at the heart of numerical applications from a very broad range of domains including structural mechanics, fluid dynamics, geophysics, medical imaging, chemistry. Among the most commonly used techniques, direct methods, based on the factorization of the system matrix, are generally appreciated for their numerical robustness and ease of use. These advantages, however, come at the price of a considerable operations count and memory footprint. The work presented in this thesis is concerned with improving the scalability of sparse direct solvers, intended as the ability to solve problems of larger and larger size. More precisely, our work aims at developing solver...
