Hi Brooks, Thanks for responding... However I'm confused by the terms used. Are you saying if I set it to 0, I would be using the processing power of all CPU's? I'm not sure how this halted comes in to play, cuz the only thing that comes to mind is to halt the machine as in shutdown.... I'm probably confusing terms here... can you expand and clarify? I just want to make sure what this all means. Also is this an option that can be modified via sysctl -w and the /etc/sysctl.conf file ? Or is this going to have to be set in a boot option? ----- Original Message ----- From: "Brooks Davis" <brooks@one-eyed-alien.net> Newsgroups: mailing.freebsd.current Sent: Tuesday, August 12, 2003 5:05 PM Subject: Re: Dual P4 2.4Ghz Xeon With Hyperthreading enabled... > > --LQksG6bCIzRHxTLp > Content-Type: text/plain; charset=us-ascii > Content-Disposition: inline > Content-Transfer-Encoding: quoted-printable > > On Tue, Aug 12, 2003 at 05:05:49PM -0600, Stephane Raimbault wrote: > > Hi Brooks, > >=20 > > I'm curious, what should that option be set to if one does have an SMP > > kernel running on 2x 2.4Ghz Xeon Processors (Hyper thread enabled) > >=20 > > Mine is currently set to > > machdep.hlt_logical_cpus: 1 > > Set it to 0 if you don't want them halted. > > -- Brooks > > --LQksG6bCIzRHxTLp > Content-Type: application/pgp-signature > Content-Disposition: inline > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.2.1 (GNU/Linux) > > iD8DBQE/OXKFXY6L6fI4GtQRAjQKAKCOAnm8DkhelZljMpO7R9/FDGyAuQCgxzAB > g17Y/Ft4QJEq94sVCy/aQHg= > =8vSx > -----END PGP SIGNATURE----- > > --LQksG6bCIzRHxTLp--
