WebNov 16, 2010 · Because a semaphore isn't a simple variable, it's a larger construct than that. Specifically, with a counting semaphore (which a binary semaphore is, effectively, with a count of 1), there's the added capability of blocking any process/thread that tries to increment the semaphore above its maximum value. A semaphore is an integer variable, shared among multiple processes. The main aim of using a semaphore is process synchronization and access control for a common resource in a concurrent environment. The initial value of a semaphore depends on the problem at hand. Usually, we use the number of resources … See more In this tutorial, we’ll dive into a powerful and well-known process synchronization tool: semaphore. We’ll look into semaphore operations, types, and its implementation. Then we’ll explore some multi-threaded cases … See more As stated above, we focus on semaphores implemented in the operating system kernel. An implementation with no busy waiting requires an … See more A semaphore is a very powerful process synchronization tool. In this tutorial, we’ve summarized the working principle of semaphores first by defining the two atomic operations: wait and signal. After gaining a better … See more In a multi-threaded environment, process synchronization means efficiently sharing of system resources by concurrent processes. Ensuring synchronized execution requires a way to coordinate processes that use … See more
