چکیده

The efficiency of the PageRank computation is important since the constantly evolving nature of the Web requires this computation to be repeated many times. PageRank computation includes repeated iterative sparse matrix-vector multiplications. Due to the enourmous size of the Web matrix to be multiplied, PageRank computations are usually carried out on parallel systems. Graph and hypergraph partitioning techniques are widely used for efficient parallelization of matrix-vector multiplications. These techniques suffer from high preprocessing overhead for PageRank algorithm. In this work, we propose Web-site-based partitioning techniques to reduce the preprocessing overhead of Parallel PageRank computation.

Hypergraph Partitioning for Faster Parallel PageRank Computation

The PageRank algorithm is used by search engines such as Google to order web pages. It uses an iterative numerical method to compute the maximal eigenvector of a transition matrix derived from the web’s hyperlink structure and a user-centred model of web-surfing behaviour. As the web has expanded and as demand for user-tailored web page ordering metrics has grown, scalable parallel computation ...

Design and Evaluation of a Method for Partitioning and Offloading Web-based Applications in Mobile Systems with Bandwidth Constraints

Computation offloading is known to be among the effective solutions of running heavy applications on smart mobile devices. However, irregular changes of a mobile data rate have direct impacts on code partitioning when offloading is in progress. It is believed that once a rate-adaptive partitioning performed, the replication of such substantial processes due to bandwidth fluctuation can be avoid...
