MatPartitioningScotchSetHostList

Specify host list file for mapping.

Synopsis

#include "petscmat.h" 
PetscErrorCode PETSCMAT_DLLEXPORT MatPartitioningScotchSetHostList(MatPartitioning part, const char *filename)

Input Parameter

part -the partitioning context
file -the name of file

Notes

The file must consist in a list of hostnames (one per line). These hosts are the ones referred to in the architecture file (see MatPartitioningScotchSetArch()): the first host corresponds to index 0, the second one to index 1, and so on.

If the name is not set, then the default "host_list" is used.
