I want the load per core, though, so my dual core AMD should give me two percentage numbers, one per core, but it only gives me one. A forum post I came across says that this number is not even an average, but the load of just the first core. Why is my second core being ignored? I get the information in a loop, as my code said, but all I get is the first of the two cores? 



Have a great day,
Alex

Keep in mind you can have up to two logical processors per core, and these
days you can have up to four or six cores, so with hyperthreading, if you
have a six core processor with HT, you'll have twelve logical processors to 
iterate through.

Logical processors which share the same core, I think, and strong emphasis
on the think, have to run at the same clockspeed until very recently, since 
all hyperthreading is, is the addition of some ALUs to the di.

Take care,
Sina

I am not looking for how many processors I have, but rather each
core's LoadPercentage. It seems like LoadPercentage goes to
NumberOfProcessors and not LogicalProcessors, and I want to get the
load for each Logical processor and not Physical processor.

Hi all,
I am playing around with WMI, trying to get the load of both cores of my
dual core AMD processor. However, I am only getting one number, not two as 
I

would expect. I thought I would get two numbers returned (I itterate

through

all the processors, at least I think I do). It is the same for all the

other

properties I have tried (clock speed, socket, more), just one piece of
information, not one per core. Is there a way to get info about each core, 
or is this processor-specific? Windows 7 64 bit. Python code is below.


import os, sys, wmi, win32com.client
speaker=win32com.client.Dispatch("Say.Tools");
c=wmi.WMI();
for p in c.win32_Processor():
 speaker.say(p.LoadPercentage);
# end for
speaker=None;

Have a great day,
Alex
