The goal of the meeting was for the participants to react to the CRESST research plan for operationalizing academic language and provide feedback and guidance for refining the plan. The participants at the meeting brought a wide range of expertise to bear on the issue and were articulate in emphasizing the critical nature of the work given the current(More)
In this article, we present several new permutations for I-matrices making these more suitable for incomplete LDU-factorization preconditioners used in solving linear systems by iterative methods. A general matrix can be transformed by row permutation as well as row and columns scaling into an I-matrix, i.e. a matrix having elements of modulus 1 on the(More)
Recent advances in multilevel LU factorizations and novel preprocessing techniques have led to an extremely large number of possibilities for preconditioning sparse, unsymmetric linear systems for solving with iterative methods. However, not all combinations work well for all systems, so making the right choices is essential for obtaining an efficient(More)
