Accelerating eigenvector and pseudospectra computation using blocked multi-shift triangular solves

30 Jul 2016 Moon Tim Poulson Jack

Multi-shift triangular solves are basic linear algebra calculations with applications in eigenvector and pseudospectra computation. We propose blocked algorithms that efficiently exploit Level 3 BLAS to perform multi-shift triangular solves and safe multi-shift triangular solves... (read more)
