Resumen:

This chapter discusses a cluster integration methodology that is amenable to the real-time analysis and implementation, based on Linux with improved temporal resolution and a high-speed TDMA interconnection bus built on top of the scalable coherent interface (SCI). It focuses mainly on a worst-case response-time analysis, its characterization using randomly generated task sets, and its verification using a system simulator. The cluster computing is a strategy used to achieve high-performance computing and resolve computationally intensive tasks such as flight simulation, and medical imaging. Two powerful tools facilitate the development of the cluster oriented applications. These tools are the message passing interface (MPI) and the parallel virtual machine (PVM). However, there are situations, in which the application execution is time constrained, such as the complex real-time image processing. MPI or PVM do not take time constraints in consideration. The proposed analysis in this chapter can be applied to a class of distributed real-time systems in which a set of nodes, running tasks under fixed priorities, communicate over a TDMA bus. © 2006 Elsevier Ltd All rights reserved.
