I used Jrockit and openjdk with Hugepage plus pin JVM to cpu socket. In previous sched numa version, I had found 20% dropping with Jrockit with our configuration. but for this version. No clear regression found. also has no benefit found. Seems we need to expend the testing configurations. :) -- Thanks Alex From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from psmtp.com (na3sys010amx160.postini.com [74.125.245.160]) by kanga.kvack.org (Postfix) with SMTP id 7389C6B002B for ; Fri, 9 Nov 2012 21:47:42 -0500 (EST) Received: by mail-oa0-f41.google.com with SMTP id k14so5702472oag.14 for ; Fri, 09 Nov 2012 18:47:41 -0800 (PST) MIME-Version: 1.0 In-Reply-To: <20121103122157.GH8218@suse.de> References: <20121025121617.617683848@chello.nl> <20121030122032.GC3888@suse.de> <20121103122157.GH8218@suse.de> Date: Sat, 10 Nov 2012 10:47:41 +0800 Message-ID: Subject: Re: [PATCH 00/31] numa/core patches From: Alex Shi Content-Type: text/plain; charset=ISO-8859-1 Sender: owner-linux-mm@kvack.org List-ID: To: Mel Gorman Cc: Peter Zijlstra , Rik van Riel , Andrea Arcangeli , Johannes Weiner , Thomas Gleixner , Linus Torvalds , Andrew Morton , linux-kernel@vger.kernel.org, linux-mm@kvack.org, Ingo Molnar , Alex Shi , "Chen, Tim C" On Sat, Nov 3, 2012 at 8:21 PM, Mel Gorman wrote: > On Sat, Nov 03, 2012 at 07:04:04PM +0800, Alex Shi wrote: >> > >> > In reality, this report is larger but I chopped it down a bit for >> > brevity. autonuma beats schednuma *heavily* on this benchmark both in >> > terms of average operations per numa node and overall throughput. >> > >> > SPECJBB PEAKS >> > 3.7.0 3.7.0 3.7.0 >> > rc2-stats-v2r1 rc2-autonuma-v27r8 rc2-schednuma-v1r3 >> > Expctd Warehouse 12.00 ( 0.00%) 12.00 ( 0.00%) 12.00 ( 0.00%) >> > Expctd Peak Bops 442225.00 ( 0.00%) 596039.00 ( 34.78%) 555342.00 ( 25.58%) >> > Actual Warehouse 7.00 ( 0.00%) 9.00 ( 28.57%) 8.00 ( 14.29%) >> > Actual Peak Bops 550747.00 ( 0.00%) 646124.00 ( 17.32%) 560635.00 ( 1.80%) >> >> It is impressive report! >> >> Could you like to share the what JVM and options are you using in the >> testing, and based on which kinds of platform? >> > > Oracle JVM version "1.7.0_07" > Java(TM) SE Runtime Environment (build 1.7.0_07-b10) > Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) > > 4 JVMs were run, one for each node. > > JVM switch specified was -Xmx12901m so it would consume roughly 80% of > memory overall. > > Machine is x86-64 4-node, 64G of RAM, CPUs are E7-4807, 48 cores in > total with HT enabled. > Thanks for configuration sharing!
