PETSc version v3.15.4-845-g6762c1643e
Sets the weights for each partition.
PetscErrorCode MatPartitioningSetPartitionWeights(MatPartitioning part,const PetscReal weights)
Logically Collective on Partitioning
|part ||- the partitioning context
|weights ||- An array of size nparts that is used to specify the fraction of
vertex weight that should be distributed to each sub-domain for
the balance constraint. If all of the sub-domains are to be of
the same size, then each of the nparts elements should be set
to a value of 1/nparts. Note that the sum of all of the weights
should be one.
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().
