Please send me a copy. I've experimented quite extensively with the optimisations in the past, I suspect the thing that has changed is the compiler technology. We saw quite a gain moving to GCC v3, but then the profiling was either too painful, or didn't gain much. The default compiler options in the Makefile are a combination of historical accident, and what worked on all the platforms I tested it on. Whilst it is interesting to learn about modern compiler technology, 18.5% faster equates to maybe ~20 Elo points, so I rapidly decided down this route lies Knuth's 'Premature Optimisation'. i.e. the best chess programs will dot these i's and cross these t's, but of themselves they won't make a dramatic difference to the skill of a program. _______________________________________________ Info-gnu-chess mailing list [email protected] http://lists.gnu.org/mailman/listinfo/info-gnu-chess
