int main(int narg, char *arg[])
int zlno_t
Defines the PartitioningSolution class.
common code used by tests
This class represents a collection of global Identifiers and their associated weights, if any.
A PartitioningSolution is a solution to a partitioning problem.
static const std::string fail
Defines the BasicIdentifierAdapter class.
int globalFail(const Comm< int > &comm, int fail)
const PartitioningSolution< Adapter > & getSolution()
Get the solution to the problem.
PartitioningProblem sets up partitioning problems for the user.
Defines the PartitioningProblem class.
size_t getActualGlobalNumberOfParts() const
Returns the actual global number of parts provided in setParts().
void solve(bool updateInputData=true)
Direct the problem to create a solution.
