Also, properly written cache-oblivious algorithms tend to recursively decompose the problem until it is small enough to fit in a cache and solve each part iteratively. The improvement effect can be noticed on large inputs. These algorithms will most probably perform quite badly on small inputs. > jb > > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to " > freebsd-questions-unsubscribe@freebsd.org" >
