What is parallel processing?

Parallel processing with Python using the multiprocessing module involves running multiple processes simultaneously to execute tasks concurrently. This can significantly speed up computation by leveraging multiple CPU cores. Here’s how it’s executed:

Setting Up Parallel Processing with multiprocessing

  1. Import the Multiprocessing Module:
    • First, you need to import the necessary components from the multiprocessing module.
    python
import multiprocessing as mp

Define the Function to Be Parallelized:

  • Create the function that you want to run in parallel. This function will be executed by multiple processes.
python
def worker_function(data):
    # Perform some computation
    result = data * data
    return result

Create a Pool of Workers:

  • The Pool class in multiprocessing is used to manage a pool of worker processes.
python
pool = mp.Pool(processes=4)  # Create a pool with 4 worker processes

Distribute Tasks Among Workers:

  • Use the map or apply methods of the Pool class to distribute tasks. The map method applies a function to a list of arguments in parallel.
python
data_list = [1, 2, 3, 4, 5, 6, 7, 8]
results = pool.map(worker_function, data_list)

Close the Pool and Wait for Completion:

  • After distributing the tasks, close the pool to prevent any more tasks from being submitted and wait for all worker processes to complete.
python
pool.close()
pool.join()

Collect and Use Results:

  • The results from the parallel processes are collected and can be used as needed.
python
  1. print(results) # Output: [1, 4, 9, 16, 25, 36, 49, 64]

Example Code

Here is a complete example demonstrating parallel processing using the multiprocessing module:

python
import multiprocessing as mp

def worker_function(data):
    # Perform some computation
    result = data * data
    return result

if __name__ == '__main__':
    # Create a pool of workers
    pool = mp.Pool(processes=4)

    # List of data to be processed
    data_list = [1, 2, 3, 4, 5, 6, 7, 8]

    # Distribute the tasks among the worker processes
    results = pool.map(worker_function, data_list)

    # Close the pool and wait for all processes to finish
    pool.close()
    pool.join()

    # Print the results
    print(results)  # Output: [1, 4, 9, 16, 25, 36, 49, 64]

Key Concepts

  • Processes vs. Threads: Unlike threading, where threads share the same memory space, multiprocessing involves creating separate memory spaces for each process. This avoids issues with the Global Interpreter Lock (GIL) in Python and allows true parallelism on multi-core systems.
  • Pool of Workers: The Pool class provides a convenient way to parallelize the execution of a function across multiple input values, distributing the input data across the processes (data parallelism).
  • Concurrency Management: The multiprocessing module provides mechanisms like Queue, Pipe, Lock, and Semaphore to manage concurrency and ensure proper communication between processes.

Benefits of Using multiprocessing

  • Improved Performance: By utilizing multiple CPU cores, tasks are executed faster compared to sequential processing.
  • Scalability: Easy to scale the number of processes based on the system’s CPU capabilities.
  • Isolation: Each process runs in its own memory space, providing isolation and reducing the risk of data corruption.

Parallel processing with the multiprocessing module in Python is a powerful technique to optimize performance for CPU-bound tasks, enabling faster and more efficient data processing.
