PetscErrorCode EPSArnoldiSetDelayed(EPS eps,PetscTruth delayed)
Collective on EPS

Input Parameters

eps - the eigenproblem solver context
delayed - boolean flag for toggling delayed reorthogonalization

Options Database Key

-eps_arnoldi_delayed - Activates delayed reorthogonalization in Arnoldi

Note

Delayed reorthogonalization is an aggressive optimization for the Arnoldi eigensolver than may provide better scalability, but it is sometimes less robust than the default algorithm.
