Getting around the GIL with POSH « python-list
5/03/2014 · The Python GIL is an artifact of the *CPython* implementation. Other implementations (f.ex Jython) do not necessarily suffer from the GIL's limitations. Threads in Python are real POSIX threads, and will get distributed over multiple processors/cores. However, they will *never* be executed simultaneously. One Python thread will run if and only if no other threads are running. To get around... Jon Perez writes: > Is anyone out there using POSH and is it reliable enough for > production use? Any plans to incorporate it into the Python > distribution?

23/01/2016 · It's only useful to the degree that your code is blocked on I/O and to the (practically insignificant) degree that some parallelization is possible around the GIL (global interpreter lock). Multi-processing is a way to keep more processors (cores, CPU "threads") busy....
Python's "multiprocessing" module feels like threads, but actually launches processes. Many people, when they start to work with Python, are excited to hear that the language supports threading.

GIL of Doom! Ian Bicking
Because we are running truly separate Python instances, each instance has it’s own GIL. You get true parallel execution of Python code (at the cost of some extra overhead). how to get spousal support in bc Comments: I can't tick off every item in your checklist, and maybe there's a way around it, but the GIL does seem to get in the way of taking our work on SCons to the next level of optimization..

I want to run a cpu intensive program in Python across multiple cores and am trying to figure out how to write C extensions to do this. Are there any code samples or tutorials on this?

  • Some of the topics we'll cover include a Python-threading API, using multiprocessing to get around the GIL, the new asyncio module, and how to choose the appropriate concurrency mechanism for the task. The only prior knowledge needed for this course is a basic understanding of Python. And by the end of this course, you'll be able to develop faster and more efficient concurrent apps in Python
  • There are various ongoing efforts to get around the GIL, including the PyPy software transactional memory (STM) work and PyParallel. Other developers are also "banging their head against that wall until it breaks". If anyone has ideas on how to remove the GIL but still keep the language as Python, he (and others) would love to hear about it.
  • A thread might block at this spot, waiting for another thread to release the lock; once that happens, the waiting thread grabs the GIL back and resumes executing your Python code. In short: While N threads are blocked on network I/O or waiting to reacquire the GIL, one thread can run Python.
  • 18/07/2005 · POSH, found at poshmodule.sourceforge.net , lets you share Python objects across processes like you would among threads and not have to resort to IPC mechanisms.
