These include techniques from AutoNUMA and the sched/numa tree and form a unified basis - it has got all the bits that look good and mergeable. With these patches applied, the mbind system calls expand to new modes of lazy-migration binding, and if the CONFIG_SCHED_NUMA=y .config option is enabled the scheduler will automatically sample the working set of tasks via page faults. Based on that information the scheduler then tries to balance smartly, put tasks on a home node and migrate CPU work and memory on the same node. They are functional in their current state and have had testing on a variety of x86 NUMA hardware. These patches will continue their life in tip:numa/core and unless there are major showstoppers they are intended for the v3.8 merge window. We believe that they provide a solid basis for future work. Please review .. once again and holler if you see anything funny! :-) From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from psmtp.com (na3sys010amx143.postini.com [74.125.245.143]) by kanga.kvack.org (Postfix) with SMTP id EB4FF6B0078 for ; Thu, 25 Oct 2012 09:09:02 -0400 (EDT) Message-Id: <20121025121617.617683848@chello.nl> Date: Thu, 25 Oct 2012 14:16:17 +0200 From: Peter Zijlstra Subject: [PATCH 00/31] numa/core patches Sender: owner-linux-mm@kvack.org List-ID: To: Rik van Riel , Andrea Arcangeli , Mel Gorman , Johannes Weiner , Thomas Gleixner , Linus Torvalds , Andrew Morton Cc: linux-kernel@vger.kernel.org, linux-mm@kvack.org, Peter Zijlstra , Ingo Molnar Hi all, Here's a re-post of the NUMA scheduling and migration improvement patches that we are working on.
