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.
