In an age where performance is key, optimizing your Python code can make a significant difference, especially with CPU-intensive tasks. Enter Parallize, a Python package designed to help you parallelize both synchronous and asynchronous functions with ease using concurrent.futures.ProcessPoolExecutor. Whether you're crunching numbers or processing data, Parallize enables you to leverage multiple CPU cores for improved performance without the hassle of managing threading or multiprocessing manually.
Why Parallel Processing?
Parallel processing allows you to execute multiple tasks simultaneously by distributing them across different CPU cores. This is particularly advantageous for tasks that are CPU-bound—where processing time is dominated by the CPU's capabilities. By paralleling your functions, you can dramatically reduce the time needed to execute extensive computations or data processing tasks.
Features You Can't Miss!
Effortlessly Parallelize Synchronous Functions: Run your standard synchronous functions in parallel across multiple processes with a simple decorator. No extra setup required!
Asynchronous Function Parallelization: Not only does Parallize support synchronous functions, but it also allows you to parallelize async functions using the
aparallizedecorator, ensuring that you get the best performance no matter your function type.Customizable Worker Count: Fine-tune your performance! Specify the maximum number of worker processes you want to utilize or allow Parallize to automatically use the available CPU cores.
Keen to See the Difference? Check Out the Mini Benchmark!
Curious about the impact of Parallize? Here are some benchmark results comparing the execution time of serial and parallel function calls:
| Test Case | Serial Execution Time | Parallel Execution Time | Speedup |
|---|---|---|---|
test_aparallize |
0:00:04.073584 | 0:00:00.017007 | 239.5x |
test_aparallize_decorator |
0:00:04.027461 | 0:00:00.014918 | 269.9x |
test_parallize |

These speeds speak for themselves—if you're looking to enhance your application’s performance, Parallize is a must-try!
Getting Started with Parallize
Installation
To start harnessing the power of parallelization, install Parallize via pip:
pip install parallize
Example Usages
Parallelizing Synchronous Functions
Simply decorate your function to run it in parallel:
from parallize import parallize
@parallize
def my_function(x, y):
return x + y
# Call the function as usual
result = my_function(1, 2)
print(result) # This will be executed in a separate process
Parallelizing Asynchronous Functions
For async functions, use the aparallize decorator:
import asyncio
from parallize import aparallize
@aparallize
async def my_async_function(x, y):
await asyncio.sleep(1)
return x + y
# Call the function as usual
result = my_async_function(1, 2)
print(result) # This will be executed in a separate process
Without Decorators
Don't want to use decorators? No problem! You can also use Parallize like this:
from parallize import parallize
def my_function(x, y):
return x + y
result = parallize(my_function)(1, 2)
print(result) # This will be executed in a separate process
Customizing the Number of Workers
Need more control? Adjust the number of worker processes with the max_workers parameter:
@parallize(max_workers=4)
def my_function(x, y):
return x + y
