Inexact Subspace Iteration to Accelerate the Solution of Linear Systems with Multiple Right-Hand Sides
We propose a two-phase acceleration technique for the solution of Symmetric and Positive Definite (SPD) linear systems with multiple right-hand sides. In the first phase we compute some partial spectral information related to the ill conditioned part of the given coefficient matrix and, in the secon...
