Improving Grid computing performance prediction usingweighted templates
2007
Understanding the performance behavior of Grid components to predict future Job submissions is
considered one of the answers to automatically select computational resources to match users’
requirements maximizing its usability. Job characterization and similarity are key components in
making a more accurate prediction. The purpose of this paper is to test how current data mining and
statistical solutions that define jobs similarity perform in production Grid environments and to
present a new method that defines template using two set of characteristics with different priorities
and weights the templates prediction accuracy level for future use. The results show that the new
method achieves in average a prediction errors than is 54 percent lower than those achieved by
using dynamic templates.
