在"Advanced Options"下,确保选择“Download free-threaded binaries(experimental)”选项,然后点击“安装”。 安装完成后,在安装目录下回有一个python3.13t.exe 的程序,这个就是无GIL 自由线程版本的入口。 测试多线程 下面代码创建并启动四个线程以并行执行一个模拟 CPU 密集任务的函数,并计算
以笔者MacOS上的安装为例，需要单击“自定”，找到Free-threaded选项，然后勾上才可以。Python官网的Python3.13安装说明的链接放在这里，供各位参考：Windows：https://docs.python.org/3.13/using/windows.html MacOS：https://docs.python.org/3.13/using/mac.html#install-freethreaded-macos 安装完成后，在命令...
测试Python3.13的no-GIL真多线程版本性能 先去官网下载3.13安装版本,我使用的是Python 3.13.1。 安装在windows下需要选择多线程版本的下载(free-threaded),不然你要自己编译。 安装好后,比正常python在目录下面多了下面的几个文件,都是加了一个t在后面: python3.13t.exe python313t.dll pythonw3.13t.exe 写一段...

8. **Download free-threaded binaries (experimental)**：下载自由线程二进制文件（实验性功能）。用户可以根据自己的需求勾选或取消勾选这些选项。安装位置也可以自定义，当前显示的安装位置是`C:\Users\28693\AppData\Local\Programs\Python\Python313`。用户可以通过点击“Browse”按钮来更改安装位置。完成配置后，...
Although the GIL does not excuse us from the need for locks, it does mean there is no need for fine-grained locking. In a free-threaded language like Java, programmers make an effort to lock shared data for the shortest time possible, to reduce thread contention and allow maximum parallelis...
