Electromagnetic researchers are often faced with long execution time and therefore algorithmic and implementation-level optimization can dramatically increase the overall performance of electromagnetism simulation using FDTD method. In this paper, we focus on acceleration implementation of 3D parallel FDTD method by taking advantage of the extended instruction sets found in modern processors, in particular...
Real-time multi-media applications are increasingly mapped on modern embedded systems based on Multiprocessor Systems-on-Chip (MPSoCs). Tasks of the applications need to be mapped on the MPSoC resources efficiently in order to satisfy their performance constraints. Exploring all the mappings, i.e. tasks to resources combinations exhaustively may take days or weeks. Additionally, the exploration is...
Peer selection strategy is one of the core issues in P2P streaming system, because peers can not only become a provider of video streaming, but also can retrieve the video stream information from its neighbor peers. In this paper the idea of similar route method was used to detect autonomous systems (AS) and substitute the known full topology information of the AS with exact position of peers in the...
Groundwater flow simulation has become one of the top international issues in new generation of environmental applications. When managing large-scale groundwater flow problems, the intensive computational ability and large amounts of memory space required for modeling are the main bottlenecks for researchers. In order to solve three-dimensional large-scale groundwater flow problems more rapidly, the...
A parallel computing procedure for computing the bounds on the {\it J}-integral in functionally graded materials is presented based on a Neumann element a-posteriori error bound. The finite element solution of {\it J}-integral is first obtained on a coarser finite element mesh, then a-posteriori bounding procedure based on the finite element error estimate is used to compute the lower and upper bounds...
