MatPartitioningSetVertexWeights#
Sets the weights for vertices for a partitioning.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatPartitioningSetVertexWeights(MatPartitioning part, const PetscInt weights[])
Logically Collective
Input Parameters#
part - the partitioning context
weights - the weights, on each process this array must have the same size as the number of local rows times the value passed with
MatPartitioningSetNumberVertexWeights()or 1 if that is not provided
Notes#
The array weights is freed by PETSc so the user should not free the array. In C/C++
the array must be obtained with a call to PetscMalloc(), not malloc().
The weights may not be used by some partitioners
