Integrating fault-tolerant feature into TOPAS parallel programming environment for distributed systems

In this paper, TOPAS-a new parallel programming environment for distributed systems-is presented. TOPAS automatically analyzes data dependence among tasks and synchronizes data, which reduces the time needed for parallel program developments. TOPAS also provides supports for scheduling, dynamic load balancing and fault tolerance. Experiments show simplicity and efficiency of parallel programming in TOPAS environment with fault-tolerant integration, which provides graceful performance degradation and quick reconfiguration time for application recovery.
