Designing an efficient parallel program usually involves iteration of performance tuning. During this process a very large amount of performance data is produced. Without a proper software tool, the process of performance tuning can be very complicated and tedious. In this paper we describe a performance tuning tool for message passing programs. Our tool(More)
Context information in mobile computing has the characteristic of being volatile. When modelling mobile context, one must consider the dynamism of a mobile computing environment. We propose a graphical technique based on conceptual graphs to model mobile context information. Our work focuses on modelling the changes of context information. This paper(More)
