I have SUSE 11.1 currently installed with KDE 3.5 and want to make sure things are running the as fast as they can.
First question is how do I know if the system is using both cores?
Second question when SUSE 11.2 comes out should I change over to 64bit?
(I plan on upgrading to KDE 4.x soon)
Hi drogers8
You may use the ‘top’ command to look at the load. It can display more than one cpu.
As for the change to 64 bit: I don’t know.
I assume this is telling me I have only one core being used?
top - 09:16:28 up 23:05, 11 users, load average: 0.12, 0.06, 0.05
Tasks: 135 total, 2 running, 133 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.8%us, 0.3%sy, 0.0%ni, 98.7%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st
Mem: 8084828k total, 1963860k used, 6120968k free, 210072k buffers
Swap: 4192956k total, 0k used, 4192956k free, 1260360k cached
cat /proc/cpuinfo
will tell you a lot about your cpu(s).
i didn’t know that top reported on each core…but, mpstat does, i
guess…try:
mpstat -P ALL
and, i think you will get something like:
Linux 2.6.22.19-0.4-default (linux103-32) 09/15/2009
04:04:03 PM CPU etc>
04:04:03 PM all etc>
04:04:03 PM 0 etc>
04:04:03 PM 1 etc>
with the first core numbered “0” and the second "12…the top line a
heading, the second line a total of all cpus…

I found out that top program doesn’t display the column by default that shows which core is being used. So you have to start top then press f then j <enter>. The display will now show a column on the far right that has the core number being used. Since I only have dual core the numbers 0 and 1 does show up. Thank you for your time and suggestions.
Start Yast - Hardware - Hardwareinfo.
Start ‘My Computer’ or start Konqueror and type in addressbar: sysinfo:/
There it will show you that you have 2 cores.
There’s also loads of plasmoids available with all kinds of system monitoring. Can be installed through Software Installer.
