Activates or deactivates delayed reorthogonalization in the Arnoldi iteration.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSArnoldiSetDelayed(EPS eps,PetscBool delayed)
Logically Collective
Input Parameters
| eps | - the eigenproblem solver context
|
| delayed | - boolean flag
|
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 sometimes makes the
solver converge less than the default algorithm.
