The Java programming language and the Java virtual machine (JVM) is designed to support concurrent programming.All execution takes place in the context of threads.Objects and resources can be accessed by many separate threads.
ThreadSafe detects Java concurrency defects: [2] [3] [4] Race conditions – which lead to incorrect or unpredictable behaviour that is difficult to reproduce in a debugger. Deadlocks [ 7 ] – caused by circular waits between threads waiting for shared resources.
The Java memory model describes how threads in the Java programming language ... It was justified by the increasing prevalence of concurrent and parallel systems, and ...
In computer programming, a thread pool is a software design pattern for achieving concurrency of execution in a computer program. Often also called a replicated workers or worker-crew model , [ 1 ] a thread pool maintains multiple threads waiting for tasks to be allocated for concurrent execution by the supervising program.
The Concurrency Representation Theorem in the actor model provides a fairly general way to represent concurrent systems that are closed in the sense that they do not receive communications from outside. (Other concurrency systems, e.g., process calculi can be modeled in the actor model using a two-phase commit protocol. [13])
In software engineering, concurrency patterns are those types of design patterns that deal with the multi-threaded programming paradigm. Examples of this class of patterns include: Active object [1] [2] Balking pattern; Barrier; Double-checked locking; Guarded suspension; Leaders/followers pattern; Monitor Object; Nuclear reaction; Reactor ...
Concurrent and parallel programming languages involve multiple timelines. Such languages provide synchronization constructs whose behavior is defined by a parallel execution model. A concurrent programming language is defined as one which uses the concept of simultaneously executing processes or threads of execution as a means of structuring a ...
Research [1] and literature [2] on concurrency testing and concurrent testing typically focuses on testing software and systems that use concurrent computing.The purpose is, as with most software testing, to understand the behaviour and performance of a software system that uses concurrent computing, particularly assessing the stability of a system or application during normal activity.
