pointing fingers at what is known as the global interpreter lock (affectionately referred to as theGIL) that prevents multiple threads of Python code from running simultaneously. Due to this, the Python multith
an Operating System achieves multitasking by dividing the process into threads. A thread is a lightweight process that ensures the execution of the process separately on the system. In Python 3, when multiple processors are running on a program...
For the uninitiated, Python multithreading usesthreadsto do parallel processing. This is the most common way to do parallel work in many programming languages. But CPython has theGlobal Interpreter Lock(GIL), which means that no two Python statements (bytecodes, strictly speaking) can execute at...
At its core, the Global Interpreter Lock is a mechanism implemented in the CPython interpreter, which is the default and most widely used implementation of Python. The GIL ensures that only one thread executes Python bytecode at a time, effectively serializing the execution of threads. While th...
See https://github.com/uqfoundation/multiprocess/tree/master/py3.12/examples for a set of examples that demonstrate some basic use cases and benchmarking for running Python code in parallel. Please feel free to submit a ticket on github, or ask a question on stackoverflow (@Mike McKerns). ...

Can anybody offer some advice regarding multithreading and using GH components with python? I read Steve Baer's post (here) and tested a few commands myself, *but* everything is slower when using the parallel function. And the interesting thing is that it gets slower with every run. As yo...
Let’s discuss how this code works: In the constructor, we create a thread and worker instance. Notice that the worker does not receive a parent, because it will be moved to the new thread. Because of this, Qt won’t be able to release the worker’s memory automatically, and therefore...
Can the Splunk Python SDK be used to run multithreaded code or for multiprocessing. I have some code which uses EventingCommand interface to generate statistical information on a large set of data. I need to use multithreading/multiprocessing to speed it up. Is it possible to use multithreading...
