  Python has supported multithreaded programming since version 1.5.2. However, the C implementation of the Python interpreter (CPython) uses a Global Interpreter Lock (GIL) to synchronize the execution of threads. There is a lot of confusion about the GIL, but essentially it prevents you from using multiple threads for parallel computing.

  Python and Concurrency •How GIL works ? –It controls the transfer of control between threads. Python interpreter determine how long a thread‟s turn runs, NOT the hardware timer. –Python uses the OS threads as a base but python itself control the transfer of control between threads. •For the above reason, true parallelism

  previous Python examples, we put the code for our thread to execute into a function. And then passed that function to the thread constructor method as a callable object using the target parameter. The other way to create a thread in Python is to define a custom subclass that inherits from the thread class and overrides its run method.

  To introduce the multiprocessing library, briefly discussing thread programming in Python is helpful . Here is a sample of how to launch a simple thread using the threading library: import time import threading def countdown(n): while n > 0: print “T-minus”, n n -= 1 time.sleep(5) print “Blastoff!” t = threading.Thread(target=countdown ...

Consequently, the GIL prevents parallel programming with multiple threads and therefore keeps Python from accessing the full performance from a CPU. In this paper, we describe a solution to this problem. We im-

  if a thread reaches an I/O statement. Thus Python threads are pre-emptive.5 Internally, Python maintains a Global Interpreter Lock to ensure that only one thread has access to the interpreter at a time. Python threads are accessible via two modules, thread.py and threading.py. The former is more primitive, thus easier to learn from. 4 First Example

  Python Multithreading Python Multithreading – Python’s threading module/package allows you to create threads as objects. In Python, or any programming language, a thread is used to execute a task where some waiting is expected. So that the main program does not wait for the task to complete, but the thread can take care of it simultaneously.

  Each process has at least one thread that corresponds to its execution. When a process creates several threads, it executes these units as parallel processes. In a single-core machine, the parallelism is approximated through thread scheduling or time slicing. The approximation consists of assigning a limited amount of time to each thread ...
