General Notes
IBM Post-Link optimization tool with
options "-O4 -omullX -see 0 -m power6" used for
433.milc 435.gromacs 436.cactusADM 482.sphinx3
options "-O4 -omullX -see 1" used for
436.cactusADM
options "-O4 -omullX -see 1 -ihf -1" used for
453.povray
options "-O4" used for
465.tonto
Whenever option "-omullX" was used during the optimization phase,
option "-imullX" was also used during the instrumentation phase.
Benchmarks bound to a processor using numactl on the submit command.
See flags file for details on settings.
