OSTI ID:5449484
ISTUD (the DO loop unrolling tool), ISTCD (the DO loop condensing tool), and ISTSB (the substitution/elimination tool) transform certain Fortran structures typically found in basic linear algebra routines. The tools are invoked in various sequences, together with other Toolpack tools, to create transformed Fortran for compilation by a vectorizing compiler. The transformed code makes fewer accesses to memory, thereby significantly improving its performance on machines with a vector architecture.
