Ibis1 is a programming environment for the development of grid applications in Java. We aim to support a wide range of applications and parallel platforms, so our example programs should also go beyond small benchmarks. In this paper we describe a number of larger applications we have developed to evaluate Ibis’ suitability for writing grid applications: a cellular automata simulator, a solver for the Satisfiability problem, and grammar-based text analysis. We give an overview of the applications, we describe their implementation, and we show performance results on a number of parallel platforms, ranging from a large supercomputer cluster to a real global grid testbed. Since all of these applications require communication between the processors during execution, it is not surprising that a supercomputer cluster proved to be the most effective platform. However, all of our applications were also efficient on a wide-area cluster system, and some of them even on a grid testbed. Since ...
