Purpose ======= The driver program pzdrive2_ABglobal. This example illustrates how to use pzgssvx_ABglobal to solve systems repeatedly with the same sparsity pattern of matrix A. In this case, the column permutation vector ScalePermstruct->perm_c is computed once. The following data structures will be reused in the subsequent call to pzgssvx_ABglobal: ScalePermstruct : perm_c LUstruct : etree On an IBM SP, the program may be run by typing: poe pzdrive2_ABglobal -r <proc rows> -c <proc columns> <input_matrix> -procs
