Concurrency Combinators for Declarative Synchronization

2004
Conference Papers

Abstract

Developing computer systems that are both concurrent and evolving is challenging. To guarantee consistent access to resources by concurrent software components, some synchronization is required. A synchronization logic, or policy, is at present entangled in the component code. Adding a new component or modifying existing components, which may require a change of the (global) synchronization policy, is therefore subjected to an extensive inspection of the complete code. We propose a calculus of concurrency combinators that allows a program code and its synchronization policy to be expressed separately; the policies include true parallelism, sequentiality, and isolation-only transactions. The calculus is equipped with an operational semantics and a type system. The type system is used to verify if a synchronization policy declared using combinators can be satisfied by program execution.

Concurrency control

In information technology and computer science, especially in the fields of computer programming, operating systems, multiprocessors, and databases, concurrency control ensures that correct results for concurrent operations are generated, while getting those results as quickly as possible. Computer systems, both software and hardware, consist of modules, or components. Each component is designed to operate correctly, i.e., to obey or to meet certain consistency rules.

Computer program

A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler.

Concurrent computing

Concurrent computing is a form of computing in which several computations are executed concurrently—during overlapping time periods—instead of sequentially—with one completing before the next starts. This is a property of a system—whether a program, computer, or a network—where there is a separate execution point or "thread of control" for each process. A concurrent system is one where a computation can advance without waiting for all other computations to complete. Concurrent computing is a form of modular programming.
