The NUMA balancing code has a few issues with determining the capacity of nodes, and using it when doing a task move.
First the NUMA balancing code does not have the equivalent of c61037e9 to fix the "phantom cores" phenomenon in the presence of SMT. Secondly, the NUMA balancing code will happily move a task from a node that is loaded to capacity, to another node that is loaded to capacity. This can leave the second node overloaded. -- 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/
