[Bug 162936] Re: why does ubuntu see 2 cpu when i have only one?

2007-11-18 Thread Andrew Frank
here the info -- hope it helps.  -- i saw that it says 'siblings' - does that 
refer to a multi-thread feature of pentium 4? and is that used in the linux 
kernel? 
(i appreciate if you point me to the literature)

thank you

andrew

[Bug 162936] Re: why does ubuntu see 2 cpu when i have only one?

2007-11-18 Thread Thomas Babut
It's not a bug, it's a feature. :)

You see 2 processors, because of the hyper-threading technology from Intel. You 
can read more about this here:
http://en.wikipedia.org/wiki/Hyper-threading

And I don't see an excessive CPU load in your top output.
