Challenge: Parallel Data Processing
Suppose you are working with a very large list of numbers and need to perform a computation on each element, such as squaring every number. Processing the entire list sequentially could be time-consuming, especially as the list grows. To speed up this operation, you can divide the list into segments and assign each segment to a separate process. Each process will work independently to compute the squares for its assigned part of the list, and then the results will be combined at the end. This approach allows you to fully utilize multiple CPU cores and significantly reduce the total processing time for large datasets.

-
Split the original list of numbers into
num_processessegments of approximately equal size. -
Each segment will be handled by a separate process.
-
This division ensures that all processes have a similar amount of work.
-
For every segment, create a new process using Python's
multiprocessinglibrary. -
Each process will receive its assigned segment and a way to return its results (such as a
Queue). -
Each process independently computes the square of each number in its segment.
-
All processes run simultaneously, making use of multiple CPU cores.
-
As each process finishes, it puts its results into a shared queue, along with its segment index.
-
Collect the results from all processes.
-
Use the segment index to ensure the final list preserves the original order of the numbers.
-
After all processes have finished, combine the results from all segments into a single list.
-
The combined list will contain the squared numbers in the same order as the original list.
