Yes, of course, unfortunately this speeds up the CPU up to max power consum= ption which isn't wanted at least at a notebook b/c temperature and fan speed are= at maximum in that case :-( It would be nice to run a grid application at lowest priority without impac= t to power / fan / temperature but OTOH have full performance for desktop applications, isn't it ? =2D-=20 MfG/Sincerely Toralf F=F6rster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 --nextPart5097950.SUz6fH7GBg Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.7 (GNU/Linux) iD8DBQBHnLfjhyrlCH22naMRAtG3AKCuvDcfhZXpKoYzE+nbmO9dcdAFUwCeO95R bLGVhsQwBGz26jyEblX5OsQ= =9R+Y -----END PGP SIGNATURE----- --nextPart5097950.SUz6fH7GBg-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
