A fast, free threading Python
If PEP-703 is accepted, subinterpreters will still be a possible choice for those who think it’ll be easier to manage. … For a (pure) Python developer free threading will be no more dangerous than GIL threading was. It’s only the native extension authors that will need to care (but Cython counts as native). I don’t think that is true. If free threading is possible, the cat will be out of the bag,
Mojoは「C言語のように速いPython」なのか - k0kubun's blog
LLVMやSwiftを作ったChris LattnerがCEOをやっている会社が、Pythonの使用感とC言語並の性能を併せ持つ言語としてMojoをアナウンスした。 まだ手元で試せる状態でリリースされてはいないが、最大35000倍Pythonより速いという。 Mojo🔥 combines the usability of Python with the performance of C, unlocking unparalleled programmability of AI hardware and extensibility of AI models. Also, it's up to 35000x faster than Python 🤯 and … deploys 🏎 pic.twitter.com/tjT09U4F80— Modular (@Modular_AI) May
Python 3.11の新機能(その3）関数呼び出しのインライン化 - python.jp
Python 3.11では、パフォーマンスチューニングの一環として、Python関数呼び出しのインライン化 が行われました。既存のPythonインタープリタのしくみを大きく変更する変更ですので、簡単に解説しておきます。 先に書いておきますが、今回行われた「関数呼び出しのインライン化」は、C/C++などの inline のように、ユーザ定義関数を呼び出し元で展開してオーバヘッドを削減するものではありません。また、Schemeなどにある末尾再帰の最適化でもありません。 cevalループ¶Pythonインタープリタは、Python 3.11の新機能(その2） 特殊化適応的インタープリタ で解説したように、Pythonのソースコードをバイトコードへ変換し、順次実行します。このバイトコードを実行する関数はPythonインタープリタの心臓部であり、CPythonソースツリーのファイル Python/c

HolyJit: A New Hope
tl;dr: We believe there is a safer and easier way of writing a Jit. Current State Today, all browsers’ Jits share a similar design. This design makes extending the language or improving its performance time-consuming and complex, especially while avoiding security issues. For instance, at the time of this writing, our Jit relies upon ~15000 lines of carefully crafted, hand-written assembly code (~

Transactional Memory (II)
Here is an update about the previous blog post about the Global Interpreter Lock (GIL). In 5 months, the point of view changed quite a bit. Let me remind you that the GIL is the technique used in both CPython and PyPy to safely run multi-threaded programs: it is a global lock that prevents multiple threads from actually running at the same time. The reason to do that is that it would have disastro
Demonstration of the effect on data safety when removing Ruby/Python GIL | Merbist
After my recent RubyConf talk and follow up post addressing the Ruby & Python’s Global Interpreter Lock (aka GVL/Global VM Lock). a lot of people asked me to explain what I meant by “data safety”. While my point isn’t to defend one approach or the other, I spent a lot of time explaining why C Ruby and C Python use a GIL and where it matters and where it matters less. As a reminder and as mentioned
