Hello everyone. I am trying to implement the Pi program in Intel Parllel studio and these two terms namely CPU time and unused CPU time has been bothering me.So thought of asking with the deveopers itself :)
As per the Intel Amplifier manual ,
CPU time - CPU Time is the sum of CPU time for all threads --ok fine i get it.!
Unused CPU time - Unused CPU Time is the total time for each core when it was either waiting or not utilized by the application... < little confusion arises over this one !
I have attached a screen shot of my program.
According to the screen shot CPU time= 13.063 seconds.
CPU unused time=13.23 seconds << My confusion becomes quad pumped over here !!
Why is the CPU unused time more than the CPU time ?
Could some one in simple terms explain the difference between these two terms.
Please have a look at the screenshot.
Thanks in advance.
