Based on the message passing interface (MPI) implement of parallel FDTD, this paper puts forward a more efficient mechanism, which decreases the time of communication and synchronization so as to enhance the efficiency of parallel FDTD. The efficient mechanism mainly consists of overlapping model and logic layer model. In addition, this paper also analyzes the performance gain in various network environments...
The basic computing models are evolving towards stronger expressiveness and higher naturalness. In grid, the focus of computation is turning from individual entities to dynamic coordination across them. Accordingly, future grid computing would be based on cooperation. This research proposes a novel model of computation namely cooperative Turing machine (CTM) for grid. It extends classical Turing machine...
