Beyond Turing: From General Computing to Domain-Specific - The "Post-Turing" Era of Domain Architectures

Abstract

Alan Turing's machine model of the universal machine model laid the theory and foundation of current computers, and layers can be regarded as an essence of computer science of current generation computers, averting the ubiquity of the universal computing; however, gradually, against Moore’s law and stepping into higher speed-computing needs, betraying the shortcomings of Turing’s model, are come up a new structure paradigm, namely specific domain architectures. Domain architecture is a style of software development which can extracts the complex business logic and build it out as a pure ‘domain model’, one that is independent of technical solutions. It is a bit like preparing an exact business blueprint of a software system: the software code may truly reflect business concepts and business rules. By defining clear boundaries and responsibilities, the domain architecture makes the system highly understandable, maintainable and capable of dynamically responding to changes in frequent business requirements. This article argues that people are entering a "post-Turing era", and people gradually turn from the pursuit of universality to pursuit of efficiency and accuracy. And that success of domain-specific architectures is no mere technology nor is it a new form rather than Turing’s form as represented by GPUs. Moreover, the future of computing will, sooner or later, be a heterogeneous era dominated by this new form.
