摘要：Many modeling process in scientific and engineering computing requires efficient solution of a series of large-scale systems of linear equations with multiple right-hand sides. Partial convergence and inexact breakdown detection mechanism in the block classical GMRES method characterized by Robbe and Sadkane is a significant progress. We consider such partial convergence from space partition, providing flexible choices for approximation search subspace at each iteration. We report our recent progress in block GMRES-type solvers, and show merits on our solvers by some typical numerical experiments.
