- Parameters
-
| [in] | vtxdist | This array describes how the vertices of the graph are distributed among the processors. Its contents are identical for every processor. |
| [in] | xadj | These store the (local) adjacency structure of the graph at each processor. |
| [in] | adjncy | These store the (local) adjacency structure of the graph at each processor. |
| [in] | ncon | This is used to specify the number of weights that each vertex has. It is also the number of balance constraints that must be satisfied. |
| [in] | nparts | This is used to specify the number of sub-domains that are desired. Note that the number of sub-domains is independent of the number of processors that call this routine. |
| [in] | tpwgts | An array of size ncon x nparts that is used to specify the fraction of vertex weight that should be distributed to each sub-domain for each balance constraint. If all of the sub-domains are to be of the same size for every vertex weight, then each of the ncon x nparts elements should be set to a value of 1/nparts. If ncon is greater than 1, the target sub-domain weights for each sub-domain are stored contiguously (similar to the vwgt array). Note that the sum of all of the tpwgts for a given vertex weight should be one. |
| [in] | ubvec | An array of size ncon that is used to specify the imbalance tolerance for each vertex weight, with 1 being perfect balance and nparts being perfect imbalance. A value of 1.05 for each of the ncon weights is recommended. |
| [in] | options | This is an array of integers that is used to pass additional parameters for the routine. The first element (i.e., options[0]) can take either the value of 0 or 1. If it is 0, then the default values are used. |
| [out] | edgecut | Upon successful completion, the number of edges that are cut by the partitioning is written to this parameter. |
| [out] | part | This is an array of size equal to the number of locally-stored vertices. Upon successful completion the partition vector of the locally-stored vertices is written to this array. |
| [in] | comm | This is a pointer to the MPI communicator of the processes that call PARMETIS. |
