Indeed. Look at "dmesg|grep CPU". There will be a line saying something like "CPU #1 launched" as one of the last messages coming directly from the kernel (in bright white during on your screen during the booting process); this shows that the second CPU is launched (the first one is named CPU #0). I guess you know the two state lines in top from Linux. FreeBSD's top doesn't do this. > >> I am importing multiple times into mysql to check load - the best I can do > >> is get 45% idle. > > If your application is not multithreaded or is linked to libc_r then > > it will only use one CPU at a time. > OK I will look at the configure options of mysql server - it is suppose to > be multi threaded. You can also start two processes, each taking 100% CPU to test. top should show you the corresponding idle time and load then. I use the distributed-net client (/usr/ports/misc/dnetc) for this kind of test. > Shouldn't top show an individual line for each cpu load though? No, not in this version of top (see above). However, you should be able to see (different or threaded) processes running on CPU#0 and CPU#1 at the same time. Hope it helps. cu Gerrit -- From owner-freebsd-smp@FreeBSD.ORG Fri Jun 4 00:59:09 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 6873C16A4CE for ; Fri, 4 Jun 2004 00:59:09 -0700 (PDT) Received: from web16905.mail.tpe.yahoo.com (web16905.mail.tpe.yahoo.com [202.1.236.185]) by mx1.FreeBSD.org (Postfix) with SMTP id AAE9443D1F for ; Fri, 4 Jun 2004 00:59:06 -0700 (PDT) (envelope-from twibmtc@yahoo.com.tw) Message-ID: <20040604075905.3422.qmail@web16905.mail.tpe.yahoo.com> Received: from [211.23.224.195] by web16905.mail.tpe.yahoo.com via HTTP; Fri, 04 Jun 2004 15:59:05 CST Date: Fri, 4 Jun 2004 15:59:05 +0800 (CST) From: =?big5?q?=20=20=20?= To: freebsd-smp@freebsd.org MIME-Version: 1.0 X-Mailman-Approved-At: Fri, 04 Jun 2004 05:44:37 -0700 Content-Type: text/plain; charset=big5 Content-Transfer-Encoding: 8bit X-Content-Filtered-By: Mailman/MimeDel 2.1.1 Subject: FreeBSD support in SMP platform X-BeenThere: freebsd-smp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: FreeBSD SMP implementation group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 04 Jun 2004 07:59:09 -0000 Dear ALL I am james wang working at IBM taiwan.

FreeBSD will see and support up to 16 CPUs, but it won't be very stable on probably more than 4 or 6. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org From owner-freebsd-smp@FreeBSD.ORG Fri Jun 4 09:05:39 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 70CAE16A4CE; Fri, 4 Jun 2004 09:05:39 -0700 (PDT) Received: from ztxmail04.ztx.compaq.com (ztxmail04.ztx.compaq.com [161.114.1.208]) by mx1.FreeBSD.org (Postfix) with ESMTP id 2ACF043D41; Fri, 4 Jun 2004 09:05:39 -0700 (PDT) (envelope-from john.cagle@hp.com) Received: from cceexg13.americas.cpqcorp.net (cceexg13.americas.cpqcorp.net [16.81.1.35]) by ztxmail04.ztx.compaq.com (Postfix) with ESMTP id AB0AB41E; Fri, 4 Jun 2004 11:05:11 -0500 (CDT) Received: from cceexc19.americas.cpqcorp.net ([16.81.1.19]) by cceexg13.americas.cpqcorp.net with Microsoft SMTPSVC(6.0.3790.0); Fri, 4 Jun 2004 11:05:09 -0500 X-MimeOLE: Produced By Microsoft Exchange V6.5.6944.0 Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Date: Fri, 4 Jun 2004 11:04:57 -0500 Message-ID: X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: FreeBSD support in SMP platform Thread-Index: AcRKSxRIelkUQ5h3R0CJYbgWHOS6IwAAnvdA From: "Cagle, John (ISS-Houston)" To: "John Baldwin" , X-OriginalArrivalTime: 04 Jun 2004 16:05:09.0938 (UTC) FILETIME=[B5FC8920:01C44A4D] cc: twibmtc@yahoo.com.tw Subject: RE: FreeBSD support in SMP platform X-BeenThere: freebsd-smp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: FreeBSD SMP implementation group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 04 Jun 2004 16:05:39 -0000 > From: John Baldwin >=20 > On Friday 04 June 2004 09:20 am, Erich Dollansky wrote: > > Hi, > > > > twibmtc@yahoo.com.tw wrote: > > > Dear ALL > > > > > > I am james wang working at IBM taiwan.

If anyone is interested in making FreeBSD more stable on 8 & 16-ways, let me know. I have a ProLiant DL740 with 8 HTT processors that we could use for testing.

When a thread is made runnable the idle CPUs contest on sched_lock so much that invariable one CPU ends up timing out on sched_lock and panic'ing.
