The interaction between surface and subsurface hydrology flow systems is important for water supplies. Accurate, efficient numerical models are needed to estimate the movement of water through unsaturated soil. We investigate a water infiltration model and develop very fast serial and parallel implementations that are suitable for a computer with a graphical processing unit (GPU).
The cost of fixing of a software defect in the later phases of the Software Development Life Cycle (SDLC) is significantly more than fixing a defect in the earlier phases of the SDLC, especially for distributed systems. The Zero Deviation Life Cycle (ZDLC) has been engineered to ensure that there is minimum deviation from the requirements and there is as little defect injection as possible between...
The High Performance Conjugate Gradient (HPCG) benchmark, proposed recently in 2013, has drawn increasingly more attention from both academia and industry. Unlike the High Performance Linpack (HPL) benchmark, which has a very high computation-to-communication ratio, HPCG contains both neigh boring and global communication that may severely degrade the parallel performance. To reduce the communication...
This paper deals with linear algebra operations on Graphics Processing Unit (GPU) with complex number arithmetic using double precision. An analysis of their uses within iterative Krylov methods is presented to solve acoustic problems. Numerical experiments performed on a set of acoustic matrices arising from the modelisation of acoustic phenomena inside a car compartment are collected, and outline...
SQL queries for big-data and multidimensional data need to be carefully coded to get maximum benefit of optimization and to improve the performance of the system and the applications involved. This is especially true for online applications where there is a race against time in populating the results set. Valuable time and cost can be saved by optimizing query statements during their design process...
To face the rapid growth of DNA sequencing data, it is of great importance to study high efficiency compression techniques to reduce the cost of storing the massive amount of sequencing data. In this paper, we propose a parallel DNA data compressor/decompress or, PLDSRC, based on the famous serial DSRC software. We first analyze the compression and decompression algorithm in DSRC and identity three...
In order to improve the analysis performance of the algorithm of parallel digital terrain analysis, a series of parallel tasks should be proceed by the appropriate partition and scheduling strategy, but the algorithm of data I/O strategy can also be optimized. Based on the conventional data I/O model, the DEM data I/O strategy of the parallel algorithm for digital terrain can be optimized by the parallel...
Xeon Phi is a high performance co-processor launched by Intel in 2012. Though Phi is specifically designed for Exascale super computer, the task assignment for Phi is yet to be studied. Based on the special needs of task assignment for Phi, this paper presents an algorithm evolved from graph bisection algorithm: a graph is formed based on the memory dependence of tasks, by traversal the graph with...
Serial estuarine hydrodynamic and sediment transport model is parallelized by MPI method based on domain decomposition techniques, the parallel model is applied to a hydrodynamic example of tidal current and sediment transport in the estuary and offshore area of Zhejiang in China. The benchmark result shows that MPI method has good parallel effect, whose speedup is accessible to 41 by 80 processors...
In this paper, we propose to investigate the compromise of the relative gains between the computation time and the energy consumption on Graphics Processing Unit (GPU).The energy consumed by GPU can not be neglected anymore, even if code acceleration is the main target. We aim to propose a prediction model of both time computation and energy consumption of linear algebra operations. Numerical experiments...
Development of inland water transport management is the major macroeconomic research of the transport. Using grey theory method, GM (1,1) management parallel calculation model is established. The model analysis the growth rate of highway, waterway and railway, forecasts the trend of the carrying capacity of water transportation, inland waterways mileage and high-grade waterways mileage in China.
In the industrial control area, WinCC is widely applied in industrial production process of real-time monitoring control and has become one of the important configuration software. But it is still unable to realize complex control algorithm with shortage of programming language. While Mat lab can deal with large amounts of data with high efficiency with its toolbox and Simulink simulation environment,...
