int HYPRE_ParaSailsSetParams (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.
