摘要: This paper studies the parallelization of restarted GMRES solver, (m), and block ILU (k) preconditioner on GPUs used in petroleum reservoir simulations. The difficulty is how to accelerate this with a variable size. In paper, parallel solution techniques for triangular systems are proposed, which work matrices an arbitrary These also level k preconditioner. Numerical experiments show that GPU-based linear solver (m) much faster than its CPU version.
