You can also press ? in top (like in many command-line apps) to show a quick help page. There should be a keypress to write a .toprc file :-) -- -- gentoo-user@gentoo.org mailing list

[gentoo-user] SMP/HT top
Hi, Was I mistaken in thinking that a true SMP system and also a hyper threading system would show two processors in top? I am trying out a new HT kernel built this morning. I've enabled both SMP support and hyper threading support but top shows only a single processor. This is not a 'problem'. More a curiosity. 1) Do SMP systems show two or more processors with top? 2) If not top then what else? 3) Should a HT system show multiple processors? Thanks, Mark -- gentoo-user@gentoo.org mailing list

Yes. You may need to press '1' once you have started top to show each processor individually. See the top manpage to see how you can set this as the default. Also note you have to be using an SMP kernel for your extra CPUs to be used at all, let alone seen by top... 2) If not top then what else? 3) Should a HT system show multiple processors? Yes, same as the above. Thanks, Mark -- Chris Boot [EMAIL PROTECTED] http://www.bootc.net/ -- gentoo-user@gentoo.org mailing list
