Trying CPython's JIT
If you haven't read Brandt Bucher's incredible rhyming Christmas Day PR, drop everything and go do it. Right now.
Welcome back! I see that big smile on your face - that poem is really something no? But what does it all mean?
Essentially, CPython now has a Just-In-Time compiler implementation, at least in distributions where that's possible. There are many flavors of JIT, but their common feature is emitting machine code very shortly before the time that code is actually run. In the case of CPython's new JIT, that's done by a method called copy-and-patch, where small snippets of code (one per Python micro-opcode) are pre-compiled to machine code, with 'holes' left for external symbols and constants that can be 'stencilled in' at runtime. Pretty neat!
I won't claim to be a JIT expert, or anything close. But I am a tinkerer, and I encourage you to be the same. After a few months of playing with the JIT and submitting a few small related PR's, I want to share the how you can get a copy of Python with the JIT enabled to play with as well. We'll also see some ways to get additional debug output, for those who really want to see the sausage get made.
Building CPython with a JIT
I don't know of any major platforms that are distributing pre-built binaries of CPython with the JIT built-in. (Please let me know if I'm wrong.) So, we'll have to build our own!
The CPython core puts a lot of effort into making Python straightforward to build. I won't rehash their setup and build instructions here, as they're fairly comprehensive.
This post is written assuming you're building in a POSIX/Linux environment - see the section at the end for information on building for Windows.
Suffice to say, we'll pick up assuming you have:
- Installed
gitandmake - Cloned the CPython repo locally. All the examples on this page use specifically the
v3.13.0b3beta branch - the JIT is evolving quickly, your experience may vary with another branch/tag. - Installed LLVM as described in the JIT-build README. At time-of-writing you should be using LLVM 18, but that may change any time.
Configuring the JIT
The key step that enables a JIT build is a specific flag passed to the ./configure script that lives in the root of the CPython repo: --enable-experimental-jit. Passing this flag will create a Makefile with the JIT build enabled! But there are actually multiple potential values for this flag:
--enable-experimental-jit=yesEnables a JIT build; The same as not passing a specific value of this flag at all
--enable-experimental-jit=yes-offEnables a built that will have the JIT, but it will be disabled by default. May be useful if you're doing some testing of the behavior of turning the JIT itself on and off. See the notes on PYTHON_JIT below.
--enable-experimental-jit=interpreterEnables just the Tier 2 Interpreter, but not the JIT. This is basically all the machinery of the JIT up to the point where specific stencils are selected to be emitted... and then they're not actually jitted. It runs exactly the same code as the JIT itself, but skips the copy-and-patch step. Performs worse than running with the full JIT, but currently provides more debuggability.
--enable-experimental-jit=noThe same as not passing this flag. Just for comprehensiveness, I suppose.
That's all the configuring you'll need to do! There are some additional configuration flags you can pass, but we'll touch on those more in the debugging and gathering statistics sections.
Building the JIT
Python's configure script will drop a Makefile into the root of the CPython repo, which has all the configuration options baked in. Once that's finished building, you can simply run make... or, if you want a little time back, make -jX, where X is the number of separate build threads to run in parallel. Staring with the number of processors on your computer (discoverable by running nproc) is a decent place to start, but it's worth experimenting up or down to see how it affects build time.
If you're rebuilding often, or weird things start happening with the build, you may need to clean up after yourself and start fresh. This is what make clean (and its more aggressive partner make distclean) are for. clean just removes generated files, while distclean removes generated files too, including the Makefile!
So to summarize - once you've cloned the CPython repo, all you need to do to build the JIT is:
|
|
Running the JIT
When the makefile completes, you should have an executable called python sitting in the root of the repo! Running code with it now will make use of the JIT!
|
|
At this point, running with JIT is, on average, about as fast as running without the JIT, so you're not likely to have seen a blazingly fast speedup. So, how can we demonstrate that the JIT is indeed running?
Turning the JIT On and Off for Different Runs
Even if you've built Python with the JIT, it can be useful to switch JIT execution on and off for different executions, or even within the same program. This can be achieved by configuring the Python build with with --enable-experimtanl-jit=yes-off will disable the JIT when Python starts. Setting the environment variable PYTHON_JIT to "1" (for enabled) or "0" (for disabled) prior to Python startup will then determine whether the JIT is active or not.
There's been some musing that having a Pythonic API to control the JIT - switch it on and off, controlling maximum member usage, possibly how fast cold traces get garbage collected, etc. However, there's hesitancy to introduce "official" API's while the JIT is still experimental. Which makes sense No is temporary, yes is forever.
Debugging and Displaying Output
With a debug build of Python, we'll have more options for displaying JIT output. Let's reconfigure and rebuild Python with:
|
|
We now have a debug build of Python! For our purposes, this will enable us to run with a couple of special environment variables that will print out what's going on with the JIT in realtime. Setting PYTHON_LLTRACE=X will display increasing volumes of information about individual "traces", or sequences of opcodes/micro-opcodes, as X increases from 1 to 5. Similarly, PYTHON_OPT_DEBUG=X prints information about how the optimizer is optimizing traces of micro-opcodes, as X ranges from 1 to 3.
Let's give ourself a short snippet of Python to run, so we can see how the output differs as we change these environment variables. If this code seems a bit contrived - it is!
|
|
PYTHON_LLTRACE=1
The lowest value of PYTHON_LLTRACE will print minimal messages, indicating that traces were created and where but providing no real detail.
$ PYTHON_LLTRACE=1 ./python src.pyCreated a proto-trace for(/home/jglass/Documents/cpython/src.py:1) at byte offset 22 -- length 11 1999001
PYTHON_LLTRACE=2
Increasing PYTHON_LLTRACE to two opens up many more details. We can see each UOp as it's added to a new trace, and which bytecodes they correspond to. Also included is information about the opcode, operand, and target of each UOp if any. (Since the operands are unique-per-run and machine-specific, I'm filtering them out here to make comparison easier.)
You can also see the result after the trace has been optimized, and some of the UOps removed. Additionally, any Bytecodes that are not currently supported by the optimizer are flagged here.

PYTHON_LLTRACE=3
In a normal JIT build, PYTHON_LLTRACE=2 and PYTHON_LLTRACE=3 are exactly the same! (At least as of the current build). But if you build with only the Tier 2 interpreter and not the JIT, you do get a few more messages about side exits and cold exits... or a lot more, depending on your code:

Buried in the middle of this, you can see similar JIT/UOp/Trace information as at level 3/4.

PYTHON_OPT_DEBUG=1
Once a hot trace has been identified and Python's bytecodes have been broken down into micro-opcodes, the optimizer takes over. It's job is to eliminent unnecessary micro-ops, to make the hot loop of code even shorter.
PYTHON_OPT_DEBUG=1 mostly enables printing error messages, like unknown opcodes or running out of space to store traces. Our little snippet from above isn't showing any error messages, but if we run a short benchmark, we can see the _INIT_CALL_PY_EXACT_ARGS uop complaining about not being able to find the function its operand references:
$ ./python -m venv venv $ ./venv/bin/python -m pip install pyperformnace $ PYTHON_OPT_DEBUG=1 ./venv/bin/python -m pyperformance run -b meteor_contestMissing function Missing function Missing function Missing function Missing function Missing function Missing function Missing function Missing function
PYTHON_OPT_DEBUG=2
As of Python 3.13.3, PYTHON_OPT_DEBUG=1 and PYTHON_OPT_DEBUG=2 are always exactly the same.
PYTHON_OPT_DEBUG=3
With value 3, PYTHON_OPT_DEBUG will spt out additional information about the UOps being processed, as well as function and code object associated with the UOp _INIT_CALL_PY_EXACT_ARGS. (This is one of those little details that is likely to change... or perhaps already has by the time you read this).

Gathering Statistics
Seeing the raw debug output as traces are created, optimized, and exited is useful for debugging the JIT, or perhaps short programs. But once your program grows to any appreciable size, these debug files become simply enormous. (The PYTHON_LLTRACE=3 output for the simple snippet above is over 20,00 lines long). In such a case, a collection of collated stats would be more helpful.
Python will generate stats about the Tier 2 interpreter and JIT (and many other things) if configured with yet another configure flag: --enable-pystats. Any code run with the -X pystats command line option will dump a statistics files to /tmp/py_stats. Note that this directory must exist before the code is run, as it will not be created for you.

The stats files themselves are fairly readable - and contain statistics about all kinds of things the interpreter did as it ran your code. Here's the actual stats output from running the above snippet - the Tier 2 stats are at the very end, if you care to scroll down:

Python bundles a script in its source repo that loads all the stats files in /tmp/py_stats and creates an nice Markdown summary of all of them:
|
|
If you scroll through the Optimization (Tier 2) Stats, you'll see things like Optimization Attempts, number of Traces Created, how many UOps were executed and which ones. The Faster CPython team maintains separate documentation on this section, since it's evolving rapidly.
To see what the output looks like with a more significant and varied workload, you can run a quick version of the pyperformance suite of benchmarks. Assuming you've built with pystats enabled, try:
|
|
This will create quite a few (~87!) temporary venvs and run each benchmark a single time, gathering stats as it goes. Running summarize_stats.py over these generated stats gives us something like:
Conclusion
So, what can you do with the JIT? It isn't, at the moment, any fast than CPython without the JIT... so why turn it on?
Test it Against Your Code. The JIT is brand-spanking-new, and while it passes the full CPython test suite, the real test of its durability is how it survives against real-world code. I'd encourage you to try to turning on the JIT, seeing what happens, and submitting any bugs you find!
Dive Deeper. Have a look in the CPython code at what the configure flags we added actually do - where does lltrace come from? How does --enable-experimental-jit ultimately impact how make runs? (This is more fodder for future blog posts - but in the meantime, go digging!).
Some specific things to look at in the CPython codebase:
- Check out the freshly-built
jit_stencils.hfile at the root of the repo, which contains the actual stencils that Python will fill in and JIT at runtime. - Search for
#ifdef _Py_JITand#ifndef _Py_JIT - Search for
#ifdef _Py_TIER2and#ifndef _Py_TIER2 - Look at
jit.cto peek at how the JIT is implemented at runtime. - Look at the
tier2_dispatchlabel inceval.c
Mess Around! Play around with the JIT and micro-ops. What patterns of loops and calls tend to lead to traces that can be well-optimized by the JIT? Can you create tooling that guides code toward optimizable hot patterns?
As always, I'd love to hear from corrections and comments, via Email, on Twitter, or on Mastodon.
Addendum: Building for Windows
If you're building for Windows, instead of having separate configure and make steps, you'll be passing build options directly to PCBuild/build.bat. The equivalent options to those discussed earlier discussed earlierare:
Linux/POSIX Windows--enable-experimental-jit=yes--experimental-jit--enable-experimental-jit=yes-off--experimental-jit-off--enable-experimental-jit=interpreter--experimental-jit-interpreterYou'll also need to follow the unique setup steps for building Python on Windows, as described by Victor Stinner. The JIT README describes how to install LLVM on Windows as well.
