The monitor object design pattern synchronizes concurrent member function execution to ensure that only one member function at a time runs within an object. It also allows object’s member functions to schedule their execution sequences cooperatively. (Pattern-Oriented Software Architecture: Patterns for Concurrent and Networked Objects) The Monitor Object design pattern synchronizes concurrent member function execution […]
The active object design pattern decouples method execution from method invocation for objects that each reside in their own thread of control.The goal is to introduce concurrency, by using asynchronous method invocation and a scheduler for handling requests. (Wikipedia:Active Object)
I continue my journey with concurrency patterns in today’s post. The Thread-Safe Interface fits very well when the critical sections are just objects.
Locking is a classical way to protect a shared, mutable state. Today, I will present the two variants, Scoped Locking and Strategized Locking.
If you don’t share, no data races can happen. Not sharing means that your thread works on local variables. This can be achieved by copying the value, using thread-specific storage, or transferring the result of a thread to its associated future via a protected data channel.
There are many well-established patterns used in the concurrency domain. They deal with synchronization challenges such as sharing and mutation but also with concurrent architectures. Today, I will introduce and dive deeper into them in additional posts.
My next mentoring program, “C++20: Get the Details”, starts in July. Registration will open in June.
Event-driven applications, such as GUIs or servers, often apply the architecture pattern Reactor. A Reactor can accept multiple requests simultaneously and distribute them to different handlers.
The Model-View-Controller (MVC) is one of the classic architectural patterns from the book “Pattern-Oriented Software Architecture, Volume 1“. It addresses interactive applications with a flexible human-machine interface.
