Is Linux using four cores?

[computer_freak_8]

I was wondering: what is a tool like cpu-z, only for Linux? I think I might only be running on two of four cores.

[drew and not u]

did you try "/proc/cpuinfo"?

[computer_freak_8]

No, but after reading your post I wrote it down and will try it when I get home to that computer.

You should set up SSH on your home PC do you can do stuff from the office/work

It's really really really easy.

 sudo apt-get install ssh

Then just set up a DynDNS and you're good to go from anywheres :)


Anyway, back on topic..... yea, Drew, that's correct. Except it's a file, so you're gonna have to open it with a text editor. I use nano when operating from terminal so I just did this. I tried in gedit but it wouldn't show, probably something to do with the encoding.

sudo nano /proc/cpuinfo

returns:

.....
model name      : Intel(R) Core(TM)2 CPU          6400  @ 2.13GHz
cpu MHz         : 2133.000
cache size      : 2048 KB
.....
cpu cores       : 2
....

Your answer lies on line 12 :D

If its GNOME, just open up the System Monitor, and it should show you how many usable cores you have

You should set up SSH... I only have internet on my cell phone when I'm at home (that's how I'm posting now). I see that it SEES all four, but is there a way to tell how many it is actually currently USING? Thanks again. computer_freak_8

Gnome system monitor did the trick - you must have posted while I was writing mine. I am glad to know I am using all four cores. Thanks, all!

Dread has the proper GUI, for a text only version, go into Console and just type "top" and that shows you a "task manager" type of layout, press F1 (I think) to switch between percentage of all cores being used or percentage per core.
most linux distros are native multi-core so nothing extra is needed.

That's right, linux will utilize multi-cores better then any windows OS, along with 64bit, and ram. Keep in mind Windows started life as an end user OS, while linux/unix started life as a server/workstation OS.
