Purpose ======= The driver program PZDRIVE2. This example illustrates how to use PZGSSVX 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: ScalePermstruct : perm_c LUstruct : etree With MPICH, program may be run by typing: mpiexec -n <np> pzdrive2 -r <proc rows> -c <proc columns> g20.rua
