The Symposium on Applied Computing has been a primary gathering forum for applied computer scientists, computer engineers, software engineers, and application developers from around the world. SAC 2010 is sponsored by the ACM Special Interest Group on Applied Computing and is hosted by the University of Applied Sciences, Western Switzerland (HES-SO) and the Ecole Polytechnique fédérale de Lausanne (EPFL).

Track Overview

Dependability is no longer restricted to critical applications, but rather becomes a cornerstone of the information society. Dependability clearly is a holistic concept: Contributing factors are not only technical, but also social, cultural (i.e. corporate culture), psychological (perceived dependability), managerial (information management and processes), and economical. Fostering learning is a key, and simplicity is generally an enabler for dependability.

Unfortunately, heterogeneous, large-scale, and dynamic software systems that typically run continuously often tend to become inert, brittle, and vulnerable after a while. The key problem is, that the most innovative mobile and pervasive systems and applications are the ones that also suffer most from a significant decrease in (deterministic) dependability when compared to traditional critical systems, where dependability and security are fairly well understood as complementary concepts and a variety of proven methods and techniques is available today. In accordance with Laprie we call this effect the dependability gap, which is widened in front of us between demand and supply of dependability, and we can see this trend further fueled by an ever increasing cost pressure.

Future systems need to close the dependability gap in face of challenges such as cross-organisational heterogeneity, massive scale, and mobility. Of course, dependability and adaptiveness can not simply be added to a system like a plug-in module. Rather, for databases, services, middleware, and software development, application developers need tools, sound methodologies, common practices, standards, architectural principles, and middleware services, to tackle the inherent complexity and emerging behavior of distributed systems and to ensure trustworthy services. Therefore, the vision of this track is on the convergence of software development tools with middleware, traditional dependability, fault tolerance, security, and adaptivity concepts, together with social and psychological aspects, to compensate for dependability degradation of running software and services.


The track provides a forum for scientists and engineers in academia and industry to present and discuss their latest research findings on selected topics in dependable and adaptive distributed systems and complex services. The track is structured in two sessions:

Session DADS-1

The first session focuses on protocols (multicast, consensus) and properties (scalability, availability, security). In particular, the following papers comprise this session:

Session DADS-2

The second session focuses on adaptation and dependability on the system and architectural level. In detail, the following papers are part of this session:
