On short recurrence Krylov type methods for linear systems with many right-hand sides
Somaiyeh Rashedi, Sebastian Birk, Andreas Frommer +1
Block and global Krylov subspace methods have been proposed as methods adapted to the situation where one iteratively solves systems with the same matrix and several right hand sid…

A CG Method for Multiple Right Hand Sides and Multiple Shifts in Lattice QCD Calculations
Sebastian Birk, Andreas Frommer
We consider the task of computing solutions of linear systems that only differ by a shift with the identity matrix as well as linear systems with several different right hand sides…
