In this paper, we introduce our work on developing parallel linear solvers and preconditioners for solving large sparse linear systems using NVIDIA GPUs. We develop a new sparse matrix-vector multiplication kernel and a sparse BLAS library for GPUs. Based on the BLAS library, several Krylov subspace linear solvers, and algebraic multi-grid (AMG) solvers and commonly used preconditioners are developed, including GMRES, CG, BICGSTAB, ORTHOMIN, classical AMG solver, polynomial preconditioner, ILU(k) and ILUT preconditioner, and domain decomposition preconditioner. Numerical experiments show that these linear solvers and preconditioners are efficient for solving the large linear systems.}, issn = {}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/ijnamb/225.html} }
