Contribution
It presents a novel approach of combining database systems with Grid computing, achieving an order of magnitude speedup over previous implementations.
Findings
SQL-based implementation is faster than Tcl-C-file-based version
Grid applications benefit from database system integration
Significant performance improvements in data-intensive tasks
Abstract
We illustrate the benefits of combining database systems and Grid technologies for data-intensive applications. Using a cluster of SQL servers, we reimplemented an existing Grid application that finds galaxy clusters in a large astronomical database. The SQL implementation runs an order of magnitude faster than the earlier Tcl-C-file-based implementation. We discuss why and how Grid applications can take advantage of database systems.
