But you are using CGROUPs, grouping all oinks into one group, and the one pert into another: requesting each group to get same total CPU. Since pert has one process only, the most he can get is 100% (not 400%), and it is quite OK for the oinks together to get 700%. > IFF ... massively parallel and synchronized ... You would be making the assumption that you had the machine to yourself: might be the wrong thing to assume. >> Good to see that you agree ... > Weeell, we've disagreed on pretty much everything ... Sorry I disagree: we do agree on the essence. :-) Cheers, Paul Paul Szabo p...@maths.usyd.edu.au http://www.maths.usyd.edu.au/u/psz/ School of Mathematics and Statistics University of Sydney Australia -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
