   Oct 23, 2012 · To answer the question you meant to ask: CPython, 3.x or otherwise, does not, never did, and likely never will, contain a JIT compiler. Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler.

   Sep 18, 2024 · Indeed, you need an earlier version of the Python interpreter, but only if you want to build Python 3.13 with the JIT support. That’s because the JIT build tool , which generates binary stencils for the copy-and-patch compiler, is a pure-Python script.

   Sep 28, 2024 · Conclusion. Python 3.13 is a big release in introducing some exciting new concepts and features to the runtime. It’s unlikely to make any immediate different to how you write and run your Python, but it’s likely that over the next few months and years as both free-threading and JIT become more mature and well established, they’ll begin to have more and more of an impact on the ...

   Jan 9, 2024 · JIT, or “Just in Time” is a compilation design that implies that compilation happens on demand when the code is run the first time. It’s a very broad term that could mean many things. I guess, technically the Python compiler is already a JIT because it compiles from Python code into Bytecode.

   Apr 11, 2024 · It’s clear that successfully compiling Python code at runtime requires not only high-quality Python-specific optimizations for the code being run, but also quick generation of efficient machine code for the optimized program. The Python core development team has the necessary skills and experience for the former (a middle-end tightly coupled to the interpreter), and copy-and-patch ...

   Does Python have a JIT compiler?

   • Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler. And there is no reason their JIT compilers would stop working when they add Python 3 support. But while I'm here, also let me address a misconception:

   Does Python need a JIT?

   • At best, it should be on par with plain Python without the JIT, which is an achievement in itself considering the extra steps involved. The long-term plan is to enhance Python’s JIT to the point where it actually makes a noticeable difference in code execution performance without taking much additional memory.

   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:

   Which Python implementation has a JIT?

   • The only Python implementation that has a JIT is PyPy. Byt - PyPy is both a Python 2 implementation and a Python 3 implementation. There is now an experimental jit on the rust python interpreter github.com/RustPython/RustPython. The Numba project should work on Python 3.

   Should CPython be included in a full JIT?

   • But a full-JIT would require those being bundled with Python and all the added overheads. A copy-and-patch JIT only requires the LLVM JIT tools be installed on the machine where CPython is compiled from source, and for most people that means the machines of the CI that builds and packages CPython for python.org.

   Does Python 313 support JIT?

   • That’s where Python 3.13 comes in. When you build Python 3.13 with the experimental JIT support, you’ll enable a lower-level execution layer called the Tier 2 interpreter, which breaks down Python bytecode into even more granular instructions.

   Oct 7, 2024 · “A JIT compiler should make CPython run faster for everyone once enabled, but Python is being conservative and leaving it off by default for now,” Cornwall said. Yet, “The ability to disable the global interpreter lock could be more disruptive, by allowing Python libraries to take advantage of more cores if the libraries can support multithreading.
