Abstract
Pervasive Grid computing platforms are composed of a variety of fixed and mobile nodes, interconnected through multiple wireless and wired network technologies. Pervasive Grid Applications must adapt themselves to the state of their surrounding environment , which includes the state of the resources on which they are executed. By focusing on a specific instance of emergency management application, we show how a complex high-performance problem can be solved according to multiple parallelization methodologies. We introduce the ASSISTANT programming model which allows programmers to express multiple versions of a same parallel module, each of them suitable for particular context situations. We show how the exemplified programs can be included in a single ASSISTANT parallel module and how their dynamic switching can be expressed. We provide experimental results demonstrating the effectiveness of the approach.
