How can I optimize my code for multi-core processors?

To optimize your code for multi-core processors, you should focus on parallelism. This involves breaking your tasks into smaller, independent units that can be executed simultaneously.

What programming languages are best for multi-core programming?

Languages like C++, Java, and Python have strong support for multi-threading and parallel processing, making them great choices.

Can you give me an example of parallel programming in Python?

Sure! You can use the concurrent.futures module to run tasks in parallel. Here's a simple example:

from concurrent.futures import ThreadPoolExecutor

def task(n):
    return n * n

with ThreadPoolExecutor() as executor:
    results = list(executor.map(task, range(10)))
print(results)

What are some common pitfalls to avoid when programming for multi-core?

Common pitfalls include race conditions, deadlocks, and excessive context switching. Always ensure proper synchronization and avoid shared state when possible.
