> What problems? performance, of course. drop_caches is really only sane for benchmarking, where you want to control for hot/cold caches. otherwise, you're almost certainly better off either letting the kernel optimize global caching, and/or fix your application to avoid polluting the cache (O_DIRECT, madvise, etc).
chip vendors could provide a drop_caches for CPUs, too, and it would also be "non-destructive". afaik, such instructions do exist, and are always privileged, for basically DOS-based the same reason. regards, mark hahn. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
