Purpose ======= The driver program pddrive1_ABglobal. This example illustrates how to use pdgssvx_ABglobal to solve systems with the same A but different right-hand side. In this case, we factorize A only once in the first call to pdgssvx_ABglobal, and reuse the following data structures in the subsequent call to pdgssvx_ABglobal: ScalePermstruct : DiagScale, R, C, perm_r, perm_c LUstruct : Glu_persist, Llu On an IBM SP, the program may be run by typing: poe pddrive1_ABglobal -r <proc rows> -c <proc columns> <input_matrix> -procs
