Does 'cat /proc/cpuinfo' show only one processor?

everything looks dead nuts, stepping, etc...

thanks...

ps: this is the output of ---> uname -a

2.6.8-24.10-smp #1 SMP Wed Dec 22 11:54:27 UTC 2004 i686 athlon i386 GNU/Linux

does the i686 and the i386 difference mean anything?

what do you think? thanks again...

I think that is the correct output for your system. Run 'uname -pmi'. This should give you the i686 athlon i386. Check out what the switches mean here. Sorry, I don't know anything about the Suse system monitor, in debian our system monitor, is cat | grep

If proc says there is two cpu's, then the kernel recognizes them. Look at the dmesg output if you want more confirmation of this. I don't know if this can be done, but run a process and time it. Then pop one of the cpu's out, run a process and time it. =)

Since you have more than one processor give this a try. If you have gkrellm up showing both processors, build a new kernel ( you don't have to install it, just for fun). When you do the ' make ' command use ' make -j4 ' . It will run one build on one processor and start another on the other. Depending on overhead it can do up to 4 things. This makes a new kernel in about 1/3 less in time. Even cooler on my quad board. Really heats up the processors.

ya, i installed "gkrellm" and the little gui says that 2 cpu's are working. you can see the little spikes in the graphs of both cpu's. so in theory, if i downgrade to a non smp kernel will i lose a cpu graph in the gkrellm screen? or will i still have 2 cpu's working but not true "smp enabled"? this has got to be a bug because all other distro's i have loaded have said i have two cpu's in gnome "system monitor" or maybe they are showing up as a "composite" view in SuSE 9.2. AAMOF, ubuntu asks for a "K7 SMP" kernel to be installed (i.e. AMD specific). qwirky...

thanks guys...

That's because you can build a kernel for the AMD k7 architcecture with Symmetric Multi Processing.

I wonder how many people here have ever compiled a kernel...

Do you count people that used genkernel? Because they compiled their kernels (i.e. they didn't use stock distro kernels) but I wouldn't say they compiled their own in the regular sense. I didn't start rolling my own until I used Slack.
