INTRODUCTION Work in the software architecture domain primarily focuses on the standard (as opposed to exceptional) behavior of the software system. However, it is crucial from the perspective of software system robustness to also account for failure occurrences. The next section gives an overview of our past work towards assisting architecting of dependable distributed systems. It is then foll...

This paper describes a development distributed platform with client-server architecture that allows developing parallel primary image processing on a cluster with variable number of workstations. The principles of the software and hardware architecture of this platform are presented underlining the versatility and the capacity of adaptation to a specific application. Experimental results show t...

Adaptive software that can react to changes in the execution environment or user requirements by switching algorithms at runtime is powerful yet difficult to implement, especially in distributed systems. This paper describes a software architecture for constructing such adaptive software and a graceful adaptation protocol that allows adaptations to be made in a coordinated manner across hosts t...

Current trends in collaborative business emphasize the importance of business process support within and between organizations. These process participants are increasingly distributed and mobile. It remains a challenge to utilize software as to share and exchange ideas and work on collaborative activities across locations and different mobile devices, while still business process aware. In this...

Centralised client/server approaches to supporting software process modelling and enactment are common, but can suffer from serious robustness, performance and security problems. We describe a decentralised architecture for software process modelling and enactment, which also incorporates distributed work coordination, task automation and system integration facilities. Our environment based on ...

Modern software development increasingly often takes place in geographically distributed contexts involving multiple development groups with different backgrounds and roles. Part or most of software systems is provided through COTS components, outsourcing, open-source, multi-party collaboration and distributed development teams. The software architecture plays an increasingly important role to ...

The ability to recover up-to-date architectural information from existing software artifacts is key to effective software maintenance, reengineering and reuse. Although architecture recovery can be facilitated with the help of current reverse engineering techniques and tools, many issues remain to be properly addressed, particularly regarding recovery of runtime abstractions (e.g., clients, ser...
