This paper presents a prototype of flood forecasting system based on Grid technologies. The system consists of workflow system for executing simulation cascade of meteorological, hydrological and hydraulic models, data management system for storing and accessing different computed and measured data, and web portals as user interfaces. The whole system is(More)
In this paper, we will present an abstraction layer for cloud computing. The abstraction layer will allow users to manipulate virtual machines as objects and simplify the process of porting applications to cloud computing. This approach could improve the flexibility of cloud computing, enable interoperability and simplify the creation of more complex(More)
In this paper, fault-tolerant feature of TOPAS 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, load balancing and fault tolerance. The main topics(More)
