Ah. That's what I did to select_idle_sibling() in a nutshell, converted the problematic large L3 packages into multiple ~core2duo pairs, modulo shared L2 'course. Bounce proof, and on Westmere, the jabbering back and forth in L3 somehow doesn't hurt as much as expected, so the things act (more or less, L2 traffic _does_ matter;) like the real deal. -Mike -- 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/
