This paper reports on the development of a library of reusable code modules for parallel applications. We illustrate the need for a variety of levels of abstraction, in which modules provide different levels of support, trading off ease of use for potential reuse. We also discuss the conflict between code reuse and high performance in this context.

Subclassing is reuse of class definitions. It is usually tied to the use of class names, thus relying on the order in which the particular classes in a program are created. This is a burden, however, both when programming and in theoretical studies. This paper presents a structural notion of subclassing for typed languages. It is a direct abstraction of the Smalltalk interpreter and the separat...

The complexity of distributed systems is a problem when designers want to evaluate their safety and liveness. Often, they are built by integration of existing components with newly developed ones. Actually, it is valuable to handle the integration of external pieces of software in the specification and testing activities. However, it is difficult to validate them formally unless doing reverse-e...

The shapes of forests of inheritance trees can affect the amount of code reuse in an object-oriented system. Designers can benefit from knowing how structuring decisions affect reuse, so that they can make more optimal decisions. We show that a set of objective measures can classify forests of inheritance trees into a set of five shape classes. These shape classes determine bounds on reuse meas...

The reuse process consists of several steps: • Design of reusable modules (Intellectual Properties, IPs): To ease the reuse of IPs design style guides should be considered already during this step. To check these style guides a code analyzer is needed. These analyzer should be adaptable to flow specific coding styles. The code analyzer will be used during the creation of IPs but also automatica...

Reuse is a fundamental concept of efficient software development. Objectoriented implementation languages offer reuse on different levels of granularity: method, class, library. While encapsulation of implementation code within methods and classes enables reuse within a project, user-defined libraries are widely used to share implementation code among different projects. The specification langu...

To help people find code that they might want to reuse, repositories of end-user code typically sort scripts by number of downloads, ratings, or other information based on prior uses of the code. However, this information is unavailable when code is new or when it has not yet been reused. Addressing this problem requires identifying reusable code based solely on information that exists when a s...

This position paper addresses the measurement of software reuse from a functional perspective rather than from a technical perspective. Many studies have observed that the potential for reuse in software goes far beyond the reuse of source lines of code and includes data, architecture , design, program and common subsystem modules, documentation, test data and various intangibles. These issues ...

Organizations with large integrated computer-based systems are often faced with the challenge of evolving their mission-critical systems in a manner that maximizes reuse opportunities, minimizes redundancies, and addresses business goals. To support these goals system developers must be provided with tools that allow them effectively assess the impact of change across the systems (impact analys...
