Its an awesome lecture sequence. Presentation is clear and concise. I appreciate presenter and openMP for reducing all the complexities with parallel programming and making it simple and easy just through few pragma statements.
The above link for the exercises no longer works. I don't know how to fix it since this youtube channel was not setup by me. To get the latest exercises, go directly to the source on GitHub .... @t . These support my latest book on OpenMP (The OpenMP Common Core: Making OpenMP Simple Again), so they aren't perfectly aligned to these videos. But they are close enough so things should work out OK
If i write a parallel program and run it on a dual core and quad core processor then the performance of both the architecture would be same whereas the power consumed by dual core architecture is more than the power consumed by quad core architecture. Am I right?
I dont know if anyone still follows this tutorial but I have a question: Why is Capacitance and Voltage are altered between two cases? Couldn't we just bump capacitance in single core case, too? Why are they altered with a multiplier of 2 exactly?
Capacitance is the ability of the circuit to store energy. So if you have 2 cores, then you can store twice as much. Now we could store more in a single core if we could fit more in there, and if the feature size changes (as in Moore's law) then the capacitance changes as well.
Power calculations are not correct. First off, the issue is related to power consumption not the energy stored in the circuit. Secondly, we are talking about digital circuits running at high frequencies (A.C.) for which power consumption calculations involve a lot of subtleties and even if you could, let's say approximate/model each processor with a single capacitor (which clearly you could not), you should know that an ideal capacitor in a sinusoidal voltage (again in digital circuits that is not the case) has a reactive power $Q = \frac{1}{2} I_{max} V_{max}$. In digital circuits, power is usually consumed during transitions between 0 and 1 states during which the digital device might have a complex gain/loss.
from this talk, I think moore's law has an issue, ONE very wrong law actually. I this also it is not correct at all for this reason. if moores law were correct it would and MUST describe this guy in this law because he obviously made more sense than all laws around this subject, after all I wish we can have is this guy moose's law event how for TEACHERs to not able to teach this way
ha ha! speak the truth man, programmer got too lazy , that's why the itanium failed, when programmers don't manage a lot of power and resources are wasted

What a lecture! I'm clapping my hands here!!!
Amazing. 9 years ago this guy knew what we were going to have now :'D.
What an explanation! Absolutely AMAZING!

Should it be 1/2 CV2 ?
This is such an awesome Video.
Thanks a lot for making this available!
Precise and clear ....

Am I right?
Great and helpful videos, thanks.

and why voltage is halfed?
Thanks a lot for this video. Very enlightening.
OMG I love this video
Would be awesome if you submitted the videos to iTunes University. Where I can download them for offline viewing.
Thank you for this awsone course.
many thanks for there are the videos. It is hepfull

This is awesome!!!!!1
can you help me about openmp please
