The concept of design patterns has recently emerged as a new paradigm in the context of object-oriented design methodology. Similar ideas are being explored in other areas of computing. In the parallel computing domain, design patterns describe recurring parallel computing problems and their solution strategies. Starting with the late 1980's, several pattern-based systems have been built for facilitating parallel application development. However, most of these systems use patterns in ad hoc manners, thus lacking a generic or standard model for using and intermixing different patterns. This substantially hampers the usability of such systems. Lack of flexibility and extensibility are some of the other major concerns associated with most of these systems. In this paper, we propose a generic (i.e., pattern- and application-independent) model for realizing and using parallel design patterns. The term architectural skeleton is used to represent the application independent, re-usable set of attributes associated with a pattern. The model can provide most of the functionalities of low level message passing libraries, such as PVM or MPI, plus the benefits of the patterns. This results in tremendous flexibility to the user. It turns out that the model is an ideal candidate for object-oriented style of design and implementation. It is currently implemented as a C++ template-library without requiring any language extension. The generic model, together with the object-oriented and library-based approach, facilitates extensibility. [ABSTRACT FROM AUTHOR] |
