MatPartitioningViewFromOptions#

View a partitioning context from the options database

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatPartitioningViewFromOptions(MatPartitioning A, PetscObject obj, const char name[])

Collective

Input Parameters#

  • A - the partitioning context

  • obj - optional object that provides the prefix used in the options database check, pass NULL to use the options prefix of A

  • name - command line option

Options Database Key#

Note#

This checks the options database, creates the viewer on-the-fly, uses it and then destroys it. Hence it should not be called in heavily used routines, rather PetscOptionsCreateViewer() should be used to construct the viewer once which can then be utilized in the heavily used routine.
