Mixed Precision Iterative Refinement with Adaptive Precision Sparse Approximate Inverse Preconditioning
Noaman Khan, Erin Carson
Hardware trends have motivated the development of mixed precision algo-rithms in numerical linear algebra, which aim to decrease runtime while maintaining acceptable accuracy. One…
The effect of approximate coarsest-level solves on the convergence of multigrid V-cycle methods
Petr Vacek, Erin Carson, Kirk M. Soodhalter
The multigrid V-cycle method is a popular method for solving systems of linear equations. It computes an approximate solution by using smoothing on fine levels and solving a system…
Mixed Precision Rayleigh Quotient Iteration for Total Least Squares Problems
Eda Oktay, Erin Carson
With the recent emergence of mixed precision hardware, there has been a renewed interest in its use for solving numerical linear algebra problems fast and accurately. The solution…
The stability of split-preconditioned FGMRES in four precisions
Erin Carson, Ieva Daužickaitė
We consider the split-preconditioned FGMRES method in a mixed precision framework, in which four potentially different precisions can be used for computations with the coefficient…
