Since PaToH is serial, it can be used in Zoltan only on a single processor. PaToH is faster than Zoltan PHG in serial mode, and often produces (slightly) better partition quality.
| Value of LB_METHOD: | HYPERGRAPH | 
| Value of HYPERGRAPH_PACKAGE: | PATOH | 
| Parameters: | |
| PATOH_ALLOC_POOL0 | non-zero  (the value of the MemMul_CellNet PATOH parameter) 0  (the default) | 
| PATOH_ALLOC_POOL1 | non-zero  (the value of the MemMul_Pins PATOH parameter) 0  (the default) | 
| USE_TIMERS | 1  (time operations and print results) 0  (don't time, the default) | 
| PHG_EDGE_SIZE_THRESHOLD | Value 0.0 through 1.0, if number of vertices in hyperedge divided by total vertices in hypergraph exceeds this fraction, the hyperedge will be omitted. | 
| ADD_OBJ_WEIGHT | Add implicit vertex (object)
weight.  Multi-weight partitioning is not yet supported, so currently either
the user-defined weight or the implicit weight will be used.
Valid values: none (the default if OBJ_WEIGHT_DIM > 0) unit or vertices (each vertex has weight 1.0, default if OBJ_WEIGHT_DIM is zero) pins or nonzeros or vertex degree (vertex weight equals number hyperedges containing it) | 
| CHECK_HYPERGRAPH | Check that the query functions
return valid input data; 0 or 1. (This slows performance; intended for debugging.) | 
| Default Values: | |
| PATOH_ALLOC_POOL0 = 0 | |
| PATOH_ALLOC_POOL1 = 0 | |
| USE_TIMERS = 0 | |
| PHG_EDGE_SIZE_THRESHOLD = 0.25 | |
| ADD_OBJ_WEIGHT = none | |
| CHECK_HYPERGRAPH = 0 | |
| Required Query Functions: | |
| ZOLTAN_NUM_OBJ_FN | |
| ZOLTAN_OBJ_LIST_FN | |
| ZOLTAN_HG_SIZE_CS_FN ZOLTAN_HG_CS_FN | |
| Optional Query Functions: | |
| ZOLTAN_HG_SIZE_EDGE_WTS_FN | |
| ZOLTAN_HG_EDGE_WTS_FN |
