Well, I have a very narrow and some sort of naive experience, so be warned. =46rom my experience, mostly compiling FreeBSD sources from scratch (deleted /usr/obj, no sophisticated caching subsystems used), compiling world and kernel with as many threads allowed as possible (using value of possible threads via PARA=3D`sysctl -n hw.ncpu` and use then $PARA as variable for "make -j${PARA} ..."), a dual core, 4-thread CPU at 3.3 GHz takes ~ 60 minutes to build world, the same as a 4-core castrated i3 with disabled SMT. Switching off SMT on the dual core results in roughly 90 - 100 minutes compile time in my case, depending on the average load of the box while compiling. So, for the INTEGER performance, I see some real benefits of SMT. The picture is somehow different for the floating point performance. Using SMT in some FPU heavy caclulations on Sandy- and Ivy-Bridge CPUs (Haswell is not available as XEON to me at this very moment), I see only 10% - a max. of 25% (roughly estimated on some crude manually timed calculations!). There is some sligt benefit, even better with most recent Ivy-Bridge than Sandy-Bridge and bot latter seem to be superior in that matter to some Westmere 6-Core XEONS we used to use a couple of years ago (this may be related to some other architectural design improvements other than SMT, like the ring bus introduced in Sandy Bridge and improved in Ivy Bridge and maybe Haswell). In earlier times (pre Sandy-Bridge era) there were issues were it would be beneficial switching off SMT for heavy FPU load in some BLAS/LAPACK based benchmark scenarios, but this knowledge is years ago with older P4 designs and early Core i7. I lost track of that.=20 To make it short: I would highly recommend using/purchasing SMT capable CPUs since there is a benefit in performance. But at the end the performance gain has to meet the costs of a SMT capable XEON. As far as I know, most of the "value" XEONs do have SMT by default. There are some disadvantages regarding the amount of memory the kernel has to consume for each core (logical and/or physical) found, so systems with small amounts of physical RAM (< 8 GiB) could run into disadvantageous situations - if I'm not wrong. But for all FreeBSD users considering using ZFS fro professional/semiprofessional usage, 8 GiB at least is a must, otherwise the ZFS system is crippling performance, not SMT. oh =20 From owner-freebsd-hardware@FreeBSD.ORG Mon Dec 8 16:16:01 2014 Return-Path: Delivered-To: freebsd-hardware@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) (using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by hub.freebsd.org (Postfix) with ESMTPS id 25C95CBF; Mon, 8 Dec 2014 16:16:01 +0000 (UTC) Received: from mail-wi0-x234.google.com (mail-wi0-x234.google.com [IPv6:2a00:1450:400c:c05::234]) (using TLSv1 with cipher ECDHE-RSA-RC4-SHA (128/128 bits)) (Client CN "smtp.gmail.com", Issuer "Google Internet Authority G2" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id AAACF8E4; Mon, 8 Dec 2014 16:16:00 +0000 (UTC) Received: by mail-wi0-f180.google.com with SMTP id n3so5263344wiv.7 for ; Mon, 08 Dec 2014 08:15:59 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:sender:in-reply-to:references:date:message-id:subject :from:to:cc:content-type; bh=PqOpWXG0dlqJaxyKysP4BixRbYlngaPff5htGfpjrr8=; b=0mogi1XcxHmlo4a+lkUT/y6UOL3iOtse8cBmVzyIfW0cxlq9oMMWgnNxSxv4ROSgzN WKL3A+KMOaHMDtBpvghE6NurOAgAf5Yir5XcYa9JWtSRYZ18ssbHoM6bjHNyBR5AM0Q+ 8VpcVFVL5KLk82YuteqVlwvODHDY08lHHbaDTKNkdKxkxWOAyWJJXREvAD4j1QDGhBPj VFX/JW7KAT5Zixm7FnH6KF3rcP85AYEvz1AxxZm63SEKIYhYxYpP7kPemlWLkFlsLr9l fuAEy6w73AIwp7fsd9ntv9xU93AoM3AFL5MdP3Jvy/isVO8V4HAQ+xZRcMjqlzeuxtnY TFrA== MIME-Version: 1.0 X-Received: by 10.194.24.103 with SMTP id t7mr46608991wjf.15.1418055358934; Mon, 08 Dec 2014 08:15:58 -0800 (PST) Sender: adrian.chadd@gmail.com Received: by 10.216.106.195 with HTTP; Mon, 8 Dec 2014 08:15:58 -0800 (PST) In-Reply-To: <20141208153925.5df90587@prometheus> References: <20141208153925.5df90587@prometheus> Date: Mon, 8 Dec 2014 08:15:58 -0800 X-Google-Sender-Auth: b8We23bshNPP5sOtfh0jrJI9qHI Message-ID: Subject: Re: HyperThreading on Intel Xeon Haswell, a benefit?

For the most part, as long as you don't fill up one of the ports on the execution engine that's doing SMT, you're okay. I've found that a memcpy heavy load (read: normal, non-zero copy network traffic) brings SMT threads to their knees. A pair of threads gets as much work done in normal UDP transmit/receive as a single non-SMT thread. It looks like it's because the ports doing memory input/output are full and there's not really any other work that's being done. I think haswell still only has one store data port per core. :( -adrian On 8 December 2014 at 06:39, O.

Good introductory info. What were your CPU models / lines / sSpec numbers above? Anyone else? Expanding... This evaluation should not be strictly confined to Intel, after all, AMD has CMT which is similar to HTT (not clear whether it's on Opteron, FX or APU lines). Though it will probably be 2016 before AMD really capitalizes and shines on their full architecture vision. By then Intel will just shift a few gears to match. So we should probably stay on subject Intel HTT for now. http://wccftech.com/amds-high-performance-processor-cores-coming-2015-giving-modular-architecture/ http://en.wikipedia.org/wiki/Simultaneous_multithreading http://en.wikipedia.org/wiki/Hyper-threading http://forums.anandtech.com/showthread.php?t=2381524 My thought is that the available evaluations of SMT are all 'old'... discontinued processors, old compilers, old schedulers, etc, all dating back to the Intel P4 arch. So let's bring this current in terms of today's Intel Haswell and AMD APU/FX processors, with new tests and community data. (Opteron is still on an even 'older' architecture [refresh] compared to FX and APU.) http://anandtech.com/show/8742/amd-announces-carrizo-and-carrizol-next-gen-apus-for-h1-2015 http://wccftech.com/amd-berlin-server-apu-glimpse-upcoming-kaveri-apu-4-steamroller-cores-512-gcn-sps/ From owner-freebsd-hardware@FreeBSD.ORG Wed Dec 10 03:29:18 2014 Return-Path: Delivered-To: freebsd-hardware@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) (using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by hub.freebsd.org (Postfix) with ESMTPS id E3E48C86 for ; Wed, 10 Dec 2014 03:29:18 +0000 (UTC) Received: from smtp.rlwinm.de (smtp.rlwinm.de [IPv6:2a01:4f8:201:31ef::e]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id A6842277 for ; Wed, 10 Dec 2014 03:29:18 +0000 (UTC) Received: from x220.rlwinm.de (p5DCCCA41.dip0.t-ipconnect.de [93.204.202.65]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by smtp.rlwinm.de (Postfix) with ESMTPSA id 2777E190BD for ; Wed, 10 Dec 2014 04:29:15 +0100 (CET) Message-ID: <5487BE0A.4030401@rlwinm.de> Date: Wed, 10 Dec 2014 04:29:14 +0100 From: Jan Bramkamp User-Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:31.0) Gecko/20100101 Thunderbird/31.3.0 MIME-Version: 1.0 To: freebsd-hardware@freebsd.org Subject: Re: Real vs available memory References: <54871680.6060705@sentex.net> <33800656-9F95-489B-9A0B-72102C685E6D@3geeks.org> In-Reply-To: Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit X-BeenThere: freebsd-hardware@freebsd.org X-Mailman-Version: 2.1.18-1 Precedence: list List-Id: General discussion of FreeBSD hardware List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 10 Dec 2014 03:29:19 -0000 On 09.12.2014 17:07, Frank Seltzer wrote: > frank_s@xxx:/home/frank_s % sysctl -a | egrep -i > 'hw.machine|hw.model|hw.ncpu' > hw.machine: i386 > hw.model: AMD Phenom(tm) II X6 1035T Processor > hw.ncpu: 6 > hw.machine_arch: i386 Reinstall your system from a FreeBSD/amd64 install medium. Your CPU is amd64 compatible.

This approach is fraught with gotchas and will bite you somewhere uncomfortable. When I last tried this (a year ago on 9.x), it couldn't get to multi-user (though I didn't investigate in depth and just moved to amd64 userland).

And that's probably what the most schedulers do. I benchmarked it on a 4th gen i3. Buildkernel got 5~10% benefit IIRC. The best way to tell is still to conduct tests with your own workload. If the claimed 5% transistor cost brings 10% benefits, that's already a win. OTTH how much you paid for it is another story. - Jia-Shiun.
