A key problem during copy-paste source code reuse is that, to reuse even a small section of code from a program as opposed to an API, a programmer must include a huge amount of additional source code from elsewhere in the same program. This additional code is notoriously large and complex, and portions can only be identified at runtime. In this paper, we propose execution record/replay as a sol...

This paper describes an investigation into the use of code replication within legacy software systems. Two cases of replication are investigated. These are replication with an individual program and replication of an entire or part of a program across a program suite. For each of the cases an example is given from code used within the commercial sector. The instances of replication are then inv...

The efficient use of a system is of paramount importance in high-performance computing. Applications need to be engineered for future systems even before the architecture of such a system is clearly known. Static performance analysis that generates performance bounds is one way to approach the task of understanding application behavior. Performance bounds provide an upper limit on the performan...

Control-flow attacks, usually achieved by exploiting a buffer-overflow vulnerability, have been a serious threat to system security for over fifteen years. Researchers have answered the threat with various mitigation techniques, but nevertheless, new exploits that successfully bypass these technologies still appear on a regular basis. In this paper, we propose ROPocop, a novel approach for dete...

In order to support the synthesis of large, complex software systems, we need to focus on issues pertaining to the architectural design of a system in addition to algorithm and data structure design. In this paper, we present an approach that is based on abstracting the architectural design of a set of problems in the form of a generic architecture , and providing tools that can be used to inst...

Software reuse is the practice of using artifacts from existing systems to build new ones. It has been shown effective for improving quality and maintainability and for reducing cost and development time. Human factors have been identified as significant barriers to a wider adoption of reuse practices in industry. In this paper we consider a tool-supported approach for systematic reuse of objec...
