RT-GRID: a real-time, fault-tolerant grid model

Computational grids bring together various distributed resources belonging to different organizations, and provide a high-performance computing environment. However, there is another application category, with the requirement of time constraints and fault tolerance, which needs to be processed in such a high-performance platform. It is necessary to incorporate real-time, fault-tolerant properties into computational grid. We propose a real-time, fault-tolerant grid model, called RT-GRID. We discuss the differences of core components between RT-GRID and computational grid. For such issues arose from real-time and fault tolerance, we study it at grid system level, and propose a monolithic architecture.
