Forgot to mention that the threads don't touch their chunks of memory concurrently, i.e. thread 2 has to wait for thread 1 to finish first. This is important to note, since the pages won't all get stuck on the first node without this behavior. -- 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/
