common code used by tests
Tpetra::Map ::local_ordinal_type zlno_t
int main()
This class represents a collection of global Identifiers and their associated weights,...
A simple class that can be the User template argument for an InputAdapter.
PartitioningProblem sets up partitioning problems for the user.
const PartitioningSolution< Adapter > & getSolution()
Get the solution to the problem.
void solve(bool updateInputData=true)
Direct the problem to create a solution.
A PartitioningSolution is a solution to a partitioning problem.
size_t getActualGlobalNumberOfParts() const
Returns the actual global number of parts provided in setParts().
