    • Computational cost estimates for parallel shared memory isogeometric multi-frontal solvers 

      Wozniak M.; Kuznik K.; Paszynski M.; Calo V.M.; Pardo D. (Computers and Mathematics with Applications, 2014-12-31)
      In this paper we present computational cost estimates for parallel shared memory isogeometric multi-frontal solvers. The estimates show that the ideal isogeometric shared memory parallel direct solver scales as $\mathcal{O}( ...
    • Performance of a multi-frontal parallel direct solver for hp-finite element method 

      Paszynski M.; Pardo D.; Torres-Verdin C. (Proceedings of the IASTED International Conference on Advances in Computer Science and Engineering, ACSE 2009, 2009-12-31)
      In this paper we present the performance of our parallel multi-frontal direct solver when applied to solve linear systems of equations resulting from discretizations of a hp Finite Element Method (hp-FEM). The hp-FEM ...
    • The value of continuity: Refined isogeometric analysis and fast direct solvers 

      Garcia D.; Pardo D.; Dalcin L.; Paszynski M.; Collier N.; Calo V.M. (Computer Methods in Applied Mechanics and Engineering, 2016-09-23)
      We propose the use of highly continuous finite element spaces interconnected with low continuity hyperplanes to maximize the performance of direct solvers. Starting from a highly continuous Isogeometric Analysis (IGA) ...
