Parallelization of XPath queries using multi-core processors
2009
Proceedings of the 12th International Conference on Extending Database Technology Advances in Database Technology - EDBT '09
Preserved Fulltext
In this study, we present experiences of parallelizing XPath queries using the Xalan XPath engine on shared-address space multi-core systems. ...
We experimentally evaluated these strategies on an x86 Linux multi-core system using a set of XPath queries, invoked on a variety of XML documents using the Xalan XPath APIs. ...
Parallel XML DOM parsing is presented in [17, 19] . The first paper uses a dynamic scheme for load-balancing among cores. ...
