Random-sketching Techniques to Enhance the Numerical Stability of Block Orthogonalization Algorithms for s-step GMRES
Ichitaro Yamazaki, Andrew J. Higgins, Erik G. Boman +1
We integrate random sketching techniques into block orthogonalization schemes needed for s-step GMRES. The resulting block orthogonalization schemes generate the basis vectors whos…

Two-Stage Block Orthogonalization to Improve Performance of -step GMRES
Ichitaro Yamazaki, Andrew J. Higgins, Erik G. Boman +1
On current computer architectures, GMRES' performance can be limited by its communication cost to generate orthonormal basis vectors of the Krylov subspace. To address this perform…
