The procedure involved in preserving the appropriate order of execution of cooperative processes is known as Process Synchronization. Such processes need to be synchronized so that their order of execution can be guaranteed. When two or more process cooperates with each other, their order of execution must be preserved otherwise there can be conflicts in their execution and inappropriate outputs can be produced.Ī cooperative process is the one which can affect the execution of other process or can be affected by the execution of other process. Concurrent use of shared resources can be a source of indeterminacy leading to issues such as deadlocks, and resource starvation.ĭesign of concurrent systems often entails finding reliable techniques for coordinating their execution, data exchange, memory allocation, and execution scheduling to minimize response time and maximise throughput. In more technical terms, concurrency refers to the decomposability property of a program, algorithm, or problem into order-independent or partially-ordered components or units.īecause computations in a concurrent system can interact with each other while being executed, the number of possible execution paths in the system can be extremely large, and the resulting outcome can be indeterminate. This allows for parallel execution of the concurrent units, which can significantly improve overall speed of the execution in multi-processor and multi-core systems. In computer science, concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the final outcome. It is a problem designed to illustrate synchronization within processes. In this article, we will focus on solving the Reader Writer problem in C++ by using Semaphores as our first approach and Monitors as our second approach.
