Understanding the Python GIL (#82)


Understanding the Python GIL

Presented by David Beazley

The Python Global Interpreter Lock (GIL) is a frequent source of debate and concern for programmers working with threads and concurrency. Although most Python programmers generally know that the GIL restricts Python's ability to utilize multiple CPUs, few know the inner details of how it actually works and how it impacts applications. This talk will dive into the inner workings of the GIL like you've never seen before. Topics include details about the execution of the Python interpreter, thread implementation, the GILs surprising behavior on multicore CPUs, and more.
