Abstract: A grid-based approach for enterprise-scale data mining that leverages database technology for I/O parallelism and on-demand compute servers for compute parallelism in the statistical computations is described. By enterprise-scale, we mean the highly-automated use of data mining in vertical business applications, where the data is stored on one or more relational database systems, and where a distributed architecture comprising of high-performance compute servers or a network of low-cost, commodity processors, is used to improve application performance, provide better quality data mining models, and for overall workload management. The approach relies on an algorithmic decomposition of the data mining kernel on the data and compute grids, which provides a simple way to exploit the parallelism on the respective grids, while minimizing the data transfer between them.
