I am wrapping a C function which performs a blocking operation (select) and then handles incoming messages.My understanding is that when a C function is going to block, the correct way to call it whil
I\'m curious why when benchmarking Python web server CherryPy using ab, with -c 7 (7 concurrent threads) it can server 1500 requests/s (about what I expect), but when I change to -c 8 it drops way dow
I was reading about the GIL and it never really specified if this includes the main thread or not (i assume so). Reason I ask is because I have a program with threads setup that modify a dictionary. T
This is risky business, and I understand the Global Interpreter Loc开发者_如何学JAVAk to be a formidable foe of parallelism. However, if I\'m using NumPy\'s C API (specifically the PyArray_DATA macro
In the current implementation of CPython, there is an object known as the \"GIL\" or \"Global Interpreter Lock\". It is essentially a mutex that prevents two Python threads from executing Python code
I\'m just starting to work on a tornado application that is having some CPU issues.The CPU time will monotonically grow as time goes by, maxing out the CPU at 100%.The system is currently designed to
Why is it that you can run Jython 开发者_开发问答and IronPython without the need for a GIL but Python (CPython) requires a GIL?Parts of the Interpreter aren\'t threadsafe, though mostly because making
Was looking to write a little web crawler in python. I was starting to investigate writing it as a multithreaded script, one pool of threads downloading an开发者_运维技巧d one pool processing results.
Suppose I have a C(++) function taking an integer, and it is bound to (C)python with python api, so I can call it from python:
Some discussion in another question has encouraged me to to better understand cases where locking is required in multithreaded Python programs.
