By substituting a recursive Fibonacci call as the process you can really get a handle on how this helps. ``` def recursive_fib(n): if n == 0 or n == 1: return n return recursive_fib(n-1) + recursive_fib(n-2) ``` pass ``args=[55]`` and watch your CPU utilization hit 100%.

[@kylebaker8502]

Hi Corey, great video covered a lot, one thing I was hoping to see here which I did not was using Pool from Multiprocessing to pass multiple parameters to a class or function. I ended up finding it after some digging using starmap with zip instead of map. To pass constants with this method import itertools and use the repeat inside the zip. Hope this helps anyone looking for this.

[@cetilly]

Wow! The use of map() is brilliant way to automatically batch the jobs for each process. Thanks for showing this!!

[@edwardwong654]

Corey is great. When you help people, and I mean really HELP people, he is just a saint. I am on Python 3.9.12 and my code does not execute properly, even though I am copying verbatim and I a stuck at the 10:20 mark. After I put in the p1/p2.start() statements, the script runs without printing the "sleep" statements. The final print statement does execute. But after I put in the p1/p2.join() statements, I get a runtime error: An attempt has been made to start a new process before the current process has finished its bootstrapping phase. This probably means that you are not using fork to start your child processes and you have forgotten to use the proper idiom in the main module: if __name__ == '__main__': freeze_support() ...

I have a case in which this will come in handy although it's hundreds of lines of code, but I bet I can wrap them all into a function to be the executor's target.

In newer versions of Python instead of using a list in args you should use tuple. So instead of writing this args=[1.5] write this args=(1.5,). It's okay to use the list version, but you will get a warning. Good tutorial btw.

[@9SMTM6]

The reason it finished the 1s future in the Multiprocessing part after the 2 and (just after) the 3s future is that the PoolExecutor limited the threads to 4 (you said yourself that it chooses the number of concurrent threads based i.e. your hardware). And your list of times to wait is reversed in duration. So it only started the future for the 1s duration AFTER the first future finished, the one with a duration of 2s. So the 1s future finished after 2+1= 3s plus overhead, so slightly after the 3s future. Edit: Aaand you realized that just shortly after. Was wondering why noone else wrote this before.

It’s the map method that would handle that. The function then would naturally need to accept multiple arguments

[@unperrier]

At 40:40 you're omitting one important thing: GaussianBlur() is an extension using a library written in C. So it can processing the image in a separately managed thread in C and relinquish execution to the python interpreter to process python bytecode on other python threads. So it's essentially a bad example, because at the low-level it behaves like multiprocessing in the sense that it can run things outside the python interpreter (multiprocessing does that in a separate process, PIL does that in a private thread, in C). So your assessment that the workload is I/O bound is incorrect. It is mostly CPU bound, but the processing you chose released the GIL, that's an unfortunate choice.

I teach children's in robotic-Club, we make games on python and robots on Arduino and Lego Mindstorm. So main idea connect to the robot by bluetooth on server PC, and using TCP send information to all client PC's and draw GUI using Real Data. Many years ago I made programm in that way, but not in Python. Your video was like quick start - simple, clear and easy to make, and easy to understand
