my system uses quad core cpu's fine. i'm running 64bit linux(2.6.36). here is 'uname -a' on my system: Linux linux 2.6.36 #2 SMP Fri Oct 22 23:42:00 CDT 2010 x86_64 x86_64 x86_64 GNU/Linux make sure you are not passing the 'nosmp' flag to the kernel during bootup(means no symmetric multi processing). and i've noticed that you are running a desktop kernel and i don't think it should but it may play a factor in the issue here. i personally run a self-compiled kernel so i can't say whether running a desktop kernel matters or not. and here is the output of ls /sys/devices/system/cpu : cpu0 cpu1 cpu2 cpu3 cpufreq cpuidle kernel_max offline online perf_events possible present probe release your system should also show something like that(listing cpu's 0 to 3). there is a great utility called htop that will show you cpu usage in real time. i've run 'make -j8' or 'make -j4' on building something like the kernel or some other source tree that'll take time to compile and i've seen the cpu usage be 100% on all cpu's when make is using 8 threads and around 80 something with 4 threads. and don't forget that the only way all your 4 cores will be used is if the program you are running is running at least 4 threads of execution. --- On Sun, 10/31/10, Chuck Payne <terrorpup@gmail.com> wrote:
I tried Yast to find out information about that, but couldn't find anything ("systems" has only "kernel settings", but apparently there no information can be found).
So all I can say that it is a 64bit system, and

I've updated Suse 11.3 2 days ago (where a new kernel version has been installed). The first lines of hwinfo are
libhd version 17.3 (x86-64) using /var/lib/hardware kernel version is 2.6 ----- /proc/cmdline ----- root=/dev/disk/by-id/ata-WDC_WD5000BEVT-75A0RT0_WD-WXB1A60V9698-part6 resume=/dev/disk/by-id/ata-WDC_WD5000BEVT-75A0RT0_WD-WXB1A 60V9698-part5 splash=silent quiet vga=0x317 ----- /proc/cmdline end -----
The kernel version:
uname -r 2.6.34.7-0.5-desktop cat /etc/SuSE-release openSUSE 11.1 (x86_64) VERSION = 11.1
1. YaST/Hardware/Hardware Information/CPU
2. >cat /proc/cpuinfo
3. #hwinfo --cpu
You should see a separate cpu record for each core,
and each record should indicate nbr of cores (or units) to be 4.

To see what kernel you are current, just do this.
uname -a
You will either see i386/i686 which is the the 32bit, if you see something like this x86_64 then you are running the 64-bits, this is from my box running 11.1.

Also, take a look at /etc/SuSE-release to see what was installed...
cat /etc/SuSE-release openSUSE 11.1 (x86_64) VERSION = 11.1
