This paper analyzes the development of the PageRank algorithm both domestic and international, expounds the practical application and development of the algorithm. On this basis, the dissertation analyzes the thinking of the traditional PageRank algorithm, sums up the advantages and disadvantages, and introduces several important PageRank improved algorithms and their thinking. The paper provides...
This paper develops a performance autotuner of the parallel sparse matrix multiplication algorithm. This autotuner can utilize the cache characters of multicore computers. It can optimize the value of performance parameters in multicore and achieve the better performance of parallel matrix multiplication algorithm. This paper proposes a parallel matrix multiplication algorithm by Using the CSR compression...
In order to improve the energy efficiency of the fault diagnosis in wireless sensor networks, we propose a tree topology based distributed fault diagnosis algorithm. The algorithm maintains high node fault detection rate and low fault alarm rate in wireless sensor networks under low node distribution density. First, the algorithm finds a good node with a multi-layer detection method, then, detects...
A new approach for the development of second-order closure models suitable for nonequilibrium turbulent shear flows is presented. The central idea is based on the implementation of a relaxation time approximation to the nonequilibrium extension of an explicit algebraic stress model. Here, the algebraic stress model is systematically derived from the full Speziale et al. 1991 (SSG) second-order closure...
