How do you find how many cpu are in your system and there details?
 
Hiiii,

How do you find how many cpu are in your system and there details?

Is this a homework question? If so, you won't get an answer here; that's against forum rules. But I can give you a clue. Go to the /proc directory and browse the files there. Look in any that have interesting names (they are text files, or at any rate behave like text files). You will find a lot of useful information about your system, including the cpu(s). Then remember where you saw it; that's how you learn things. You don't learn much from getting answers served up to you on a plate.

will tell you about the number of cpu's which are present in your system. Well you must explore

/proc
directory, hazel is right, it contains very useful information about you system. These kinda questions are just a google search away, so it's better that you first google your problem and do a little research about it.
Cheers!

DuckDuckGo your model# and the term specs ;)

You will know how many cpu's you have and each details by running these as root:
Code:
sudo cat /proc/cpuinfo
Also your cpu's are listed with memory and swap consumption by viewing what is displayed on terminal by this command:
Code:
htop -d 5
reports are quick enough for you to notice what cpu load is taking and which of them is busiest. To return to the terminal prompt just press "q".

Hope that helps. Good luck and enjoy.

m.m.

I should have said too, if it was a used box, open it up...

Ha ha ha jamison you are really smart. Your solution is the first in order.

mmm, perhaps a homework problem but where do you find reliable info as to cpu's from native Windows tools, can you say they are threads or genuine cores on the Win system?

also

htop -d 5
bash: htop: command not found
and no I have not installed htop

As root, type

Code:
dmidecode --type processor
This will give all details about your cpus. The # of cores, the # of threads, the kitchen sink and everything.

Assuming, of course, that you have dmidecode installed.

True, but I didn't want to sound like a broken record and repeat what already been said.

dmidecode can be installed very easily if needed.

Seems like an odd (((until you look at the OP's other 3 posts...
(...note time, date not so much space):scratch:))) and hinder(ed)ing HW-Q? :confused: :hattip: (No pun on ed(\*human!*) :D)

$ sudo apt-get install cpuid hwinfo util-linux cpufrequtils

$ cat /proc/cpuinfo | less

$ cpuid | grep -i "cpu count"

$ lscpu

$ cpufreq-info

$ sudo hwinfo | grep -i units/processor

And probably a dozen other ways. BITD it would boot up with a penguin on top per CPU.
