In computer programming, a mutual exclusion (mutex) is aprogramobjectthat prevents multiplethreadsfrom accessing the same shared resource simultaneously. A shared resource in this context is acodeelement with a critical section, the part of the code that should not be executed by more than one th...
A mutual exclusion (mutex) is a program object that prevents simultaneous access to a shared resource. This concept is used in concurrent programming with a critical section, a piece of code in which processes or threads access a shared resource. Only one thread owns the mutex at a time, th...

If you have very well-behaved code with short critical sections that are highly contended, and you're looking for better performance on SMP, the adaptive mutex may be worth a try. The work can be found in the Git history. The commit which updates thelinuxthreads/ChangeLogfile ishere; the...
mutual exclusion (std::mutex), condition variables (std::condition_variable), and many other features.In C++14, in addition tomutex, there is ashared_mutexwhich is an instance of the class located in<shared_mutex>header. In the first post, we explain usingshared mutexes locking in Mode...
In CPython, multi-threading is supported by introducing aMutexknown as Global Interpreter Lock (aka GIL). It is to prevent multiple threads from accessing the same Python object simultaneously. This make sense, you wouldn’t want someone else to mutate your object while you are processing it....
Semaphore: n-member access to a resource That is, a mutex can be used to syncronize access to a counter, file, database, etc. A sempahore can do the same thing but supports a fixed number of simultaneous callers. For example, I can wrap my database calls in a semaphore(3) so th...

It is sometimes called a monitor, a critical section, a mutex, or a binary semaphore, but regardless of the name, it provides the same basic functionality. The lock provides Enter and Exit methods, and once a thread calls Enter, all attempts by other threads to call Enter will cause the...
