If it is assigned to Process 1, the other process (Process 2) needs to wait until Process 1 frees that resource (as shown in Figure 2). Figure 2: A process accessing a shared resource if available, based on some synchronization technique. Another synchronization requirement which needs to be considered is the order in which particular processes ...
The composition model is an extension on the check-out/check-in model. This model allows developers to think in configurations instead of individual files. Although the complete check-out/check-in model is represented in the composition model, it enables the use of different strategies for updating through the use of improved support for the management of configurations.
Overhead Ignored: Amdahl's Law neglects overheads associated with concurrency, including coordination, synchronization, inter-process communication, and concurrency control. Notably, merging data from multiple threads or processes incurs significant overhead due to conflict resolution, data consistency, versioning, and synchronization. [9]
With the (IBM) SPMD model the cooperating processors (or processes) take different paths through the program, using parallel directives (parallelization and synchronization directives, which can utilize compare-and-swap and fetch-and-add operations on shared memory synchronization variables), and perform operations on data in the shared memory ...
A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.

Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time . Systems that operate with all parts in synchrony are said to be synchronous or in sync —and those that are not are asynchronous .
The outlet quoted an arrest affidavit as stating that she was stabbed 14 times by Alvelo after she gave her a $2 tip for delivering the pizza. She suffered a ruptured lung and wounds to her chest ...
