SIAM Journal on Numerical Analysis, Vol. 41, No. 2 (2004), pp. 589-604 (16 pages) We study the computation of the orthogonal spline collocation solution of a linear Dirichlet boundary value problem ...
Abstract: The Preconditioned Conjugate Gradient (PCG) algorithm is a widely-used iterative method for solving sparse linear systems. The sparse matrix-vector multiplication (SpMV) operation involved ...
Abstract: The preconditioned conjugate gradient method (PCG) is a popular method for solving linear systems at scale. PCG requires frequent blocking allreduce collective operations that can limit ...
