   2 days ago · Starting with the 3.13 release, CPython has experimental support for a build of Python called free threading where the global interpreter lock (GIL) is disabled. Free-threaded execution allows for full utilization of the available processing power by running threads in parallel on available CPU cores.

   In this lesson, I’ll be talking about the two new experimental performance features. 00:08 Python 3.13 includes two experimental features, free threading and a JIT. 00:15 I put quotes surrounding “includes” because they’re not there by default. These features are available when you’re building Python as optional flags.

   How to enable free threading & JIT compiler in Python?

   • Navigate into the parent folder containing the Python source code, which you extracted from the downloaded archive in the previous step: Make sure to adjust the path as necessary if you opted for a more recent Python 3.13 release. Now, you can run the configure script with custom build flags to enable free threading and the JIT compiler:

   Does Python 313 have a JIT compiler?

   • Python 3.13 brings two experimental features that open the gateway to much better performance in future releases. These groundbreaking changes will require thorough testing, which is why they’re not currently enabled by default. However, you can try out free threading and the JIT compiler today by building Python from source code.

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.

   How do I enable JIT in Python?

   • In this case, you enable the JIT on top of the stock Python, 3.13.0rc1, which doesn’t come with free threading. If you’d like to have both features enabled simultaneously, then you can either pick 3.13.0rc1t as the basis or append the --disable-gil configuration option to the environment variable.

    Oct 16, 2024 · When you use the free-threaded build, the GIL is included in the binary but disabled by default. If for some reason you want to re-enable the GIL in the free-threaded version, you can use the command-line option -X gil=1, or set the environment variable PYTHON_GIL to 1.
