Flexible and efficient transfer of multidimensional data in grid

Abstract

When grid applications operate on multidimensional data, query and transfer are two widely used operations. To support flexible query operation, a storage structure based on partition the multidimensional data is adopted. However, this will degrade the performance of the transfer. This paper investigates this problem and proposes the logically linked file (LLF) approach to solve it. By logically linking the qualified non-continuous data sets to a LLF and providing a specific transfer mechanism for LLF, the transfer performance is improved. The experiment shows the transfer performance isn't affected by the storage structure any more.
