What is SMP

[ordoni]

Is SMP same as HyperThreading ?

[serz]

No, SMP stands for Symmetric Multi Processors. It's a PC with 2 or more processors.

If you have a P4 with HyperThreading, your distro will see it as a dual processor and installl the smp kernel. I have a dual Xeon w/HyperThreading and SuSE recognizes them as being 4 processors just as WinXP Pro does. Take a look at this screenshot.

where can you find info about processors........is there a command ?

[LondoJowo]

Open up a terminal (Konsole), type or cut/paste the following and hit enter.

cat /proc/cpuinfo

[LondoJowo]

Here's what I get when I run the command.

this is sweet.....................4 processors :rock:

[bigtomrodney]

Ah it's not really, but it does help with bottlenecking and by splitting out processes dynamically. I work with a server that reports 8 CPUs...

Ah it's only got 4.. only...
