DMLabelGetValueISGlobal#

Get an IS of all values that the DMlabel takes across all ranks

Synopsis#

#include "petscdmlabel.h"   
#include "petscsection.h"   
PetscErrorCode DMLabelGetValueISGlobal(MPI_Comm comm, DMLabel label, PetscBool get_nonempty, IS *values)

Collective

Input Parameter#

  • comm - MPI communicator to collect values

  • label - the DMLabel, may be NULL for ranks in comm which do not have the corresponding DMLabel

  • get_nonempty - whether to get nonempty stratum values (akin to DMLabelGetNonEmptyStratumValuesIS())

Output Parameter#

  • values - the value IS

Notes#

The values should be destroyed when no longer needed.

This is similar to DMLabelGetValueIS() and DMLabelGetNonEmptyStratumValuesIS(), but gets the (nonempty) values across all ranks in comm.
