yes I see but why I do not see 2 CPUs (cores) in the output of the
'top' command ?
I do remember that INTEL Pentium with hyper threading is seen as 2 CPUs.
It sees two cores. It uses two

thanks ... I agree
Now, if you want software that specifically uses both cores

again ... I agree with you... but I did not have a lot of choices...
this contest http://www.novell.com/linux/ready/. Two days ago I've received
Novell an HP nx6325 with SLED10 preinstalled. See
Unfortunately, SLED10 is not stable enough. It crashed in the last two
days 3 times for no apparent reason. Or, to bi a little bit more precise. It
crashed 2 times after burning CD with K3B. On top of that
'kacpid,acpid,acpi' does not work correctly. 'kacpid' is pushing CPU to run
'dmesg' is telling me that the SMP is disabled. I've decided to explore
other options, like ubuntu. I've heard a lot of very positive comments about
it. So, here I am... learning debian based distro.
My plan is to install MS WIN XP via vmware player. I am going to give this
laptop to my daughter. She needs MS WINDOWS in school. So, I hope that the
vmware, with WIN XP as a guest OS, will run on on one core and the host OS
(ubuntu) will use the second core.... therefore I need a tool to see if
both cores are used or not.
Any help/hint/pointer to RTFM is more than welcome
