Class Documentation

class LinearGraphPartitioner : public opensn::GraphPartitioner

Basic linear partitioner intended for testing only.

Partitions cells by their linear global_id index rather than by graph connectivity, so results are generally poor for unstructured grids.

Public Functions

explicit LinearGraphPartitioner(const InputParameters &params)

virtual std::vector<int> Partition(const std::vector<std::vector<uint64_t>> &graph, const std::vector<Vector3> &centroids, int number_of_parts) override

Given a graph. Returns the partition ids of each row in the graph.
