Arguments
=========

A      (input) SuperMatrix*
       The distributed input matrix A of dimension (A->nrow, A->ncol).
       The type of A can be: Stype = SLU_NR_loc; Dtype = SLU_S; Mtype = SLU_GE.

grid   (input) gridinfo_t*
       SuperLU's 2D process mesh.

ScalePermstruct (output) sScalePermstruct_t*
       ScalePermstruct->perm_r stores the permutation obtained from HWPM.
