(HYPRE_Solver solver, double thresh,
int nlevels)
Set the threshold and levels parameter for the ParaSails preconditioner.
Documentation
Set the threshold and levels parameter for the ParaSails
preconditioner. The accuracy and cost of ParaSails are
parameterized by these two parameters. Lower values of the
threshold parameter and higher values of levels parameter
lead to more accurate, but more expensive preconditioners.
- Parameters:
- solver - [IN] Preconditioner object for which to set parameters.
thresh - [IN] Value of threshold parameter,
thresh
.
The default value is 0.1.
nlevels - [IN] Value of levels parameter,
nlevels.
The default value is 1.
