Genetic Algorithms and Compiler Optimizations

Posted by michael on from the when-it-absolutely-positively-has-to-run-overnight dept.

mfago writes "Scott Robert Ladd has written an enlightening article and accompanying software package that utilizes genetic algorithms to optimize the optimization flags fed to a compiler. Those who have tried to squeeze the last drop of performance from a code know that it can be very difficult to determine the set of optimization flags beyond -O3 (with gcc for example) that yields the best performance. Lots of background links included in the article."

    This is a new low. Next we'll see papers
    on using genetic algorithms to find the best
    channel on TV.

    What would be interesting is a genetic system
    to select meso-scale optimizations in a
    compile back-end, for example.
