Klib read synchronization8/25/2023 ![]() Processes' access to critical section is controlled by using synchronization techniques. Thread synchronization is defined as a mechanism which ensures that two or more concurrent processes or threads do not simultaneously execute some particular program segment known as critical section. Thread or process synchronization Figure 1: Three processes accessing a shared resource ( critical section) simultaneously. Producer-Consumer: In a producer-consumer relationship, the consumer process is dependent on the producer process until the necessary data has been produced.Įxclusive use resources: When multiple processes are dependent on a resource and they need to access it at the same time, the operating system needs to ensure that only one processor accesses it at a given point in time. Thus, parallel programming requires synchronization as all the parallel processes wait for several other processes to occur. Then, they are joined again and leave the system. ![]() After being serviced, each sub-job waits until all other sub-jobs are done processing. Mentioned below are some of the main needs for synchronization:įorks and Joins: When a job arrives at a fork point, it is split into N sub-jobs which are then serviced by n tasks. The need for synchronization does not arise merely in multi-processor systems but for any kind of concurrent processes even in single processor systems. Process synchronization primitives are commonly used to implement data synchronization. Data synchronization refers to the idea of keeping multiple copies of a dataset in coherence with one another, or to maintain data integrity. Process synchronization refers to the idea that multiple processes are to join up or handshake at a certain point, in order to reach an agreement or commit to a certain sequence of action. In computer science, synchronization refers to one of two distinct but related concepts: synchronization of processes, and synchronization of data.
