Purpose
=======

The driver program PSDRIVE1.

This example illustrates how to use PSGSSVX to
solve systems with the same A but different right-hand side,
possibly with different number of right-hand sides.
In this case, we factorize A only once in the first call to
PSGSSVX, and reuse the following data structures
in the subsequent call to PSGSSVX:
       ScalePermstruct  : DiagScale, R, C, perm_r, perm_c
       LUstruct         : Glu_persist, Llu

With MPICH,  program may be run by typing:
   mpiexec -n <np> psdrive1 -r <proc rows> -c <proc columns> big.rua
