Purpose ======= The driver program psdrive_ABglobal. This example illustrates how to use psgssvx_ABglobal with the full (default) options to solve a linear system. Five basic steps are required: 1. Initialize the MPI environment and the SuperLU process grid 2. Set up the input matrix and the right-hand side 3. Set the options argument 4. Call psgssvx_ABglobal 5. Release the process grid and terminate the MPI environment On an IBM SP, the program may be run by typing poe psdrive_ABglobal -r <proc rows> -c <proc columns> <input_file> -procs
