An adaptive algorithm for mining association rules on shared-memory parallel machines
收藏 引用
DISTRIBUTED AND parallel databases 2001年 第2期9卷 99-132页
作者: Cheung, DW Hu, K Xia, SW Univ Hong Kong Dept Comp Sci & Informat Syst Hong Kong Hong Kong Peoples R China Tsinghua Univ Dept Automat Beijing 100084 Peoples R China
Mining association rules from large databases is very costly. We propose to develop parallel algorithms for this task on shared-memory multiprocessor (SMP). All proposed parallel algorithms for other paradigms follow ... 详细信息

CPU and incremental memory allocation in dynamic parallelization of SQL queries
收藏 引用
parallel COMPUTING 2002年 第4期28卷 525-556页
作者: Hameurlain, A Morvan, F Univ Toulouse 3 IRIT F-31062 Toulouse France
In order to re-adjust the parallel execution of SQL queries in case of metric estimation or discretization errors, we propose an incremental parallelization method which carries out simultaneously both scheduling and ... 详细信息

Multidimensional declustering schemes using Golden Ratio and Kronecker sequences
收藏 引用
IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING 2003年 第3期15卷 659-670页
作者: Chen, CM Bhatia, R Sinha, RK Telcordia Technol Morristown NJ 07960 USA Bell Labs Murray Hill NJ 07974 USA AT&T Labs Res Middletown NJ 07748 USA
We propose a new declustering scheme for allocating uniform multidimensional data among parallel disks. The scheme, aimed at reducing disk access time for range queries, is based on Golden Ratio Sequences for two dime... 详细信息

A hypergraph based approach to declustering problems
收藏 引用
DISTRIBUTED AND parallel databases 2001年 第3期10卷 269-288页
作者: Liu, DR Wu, MY Natl Chiao Tung Univ Inst Informat Management Hsinchu Taiwan
parallelizing I/O operations via effective declustering of data is becoming essential to scale up the performance of parallel databases or high performance systems. Declustering has been shown to be a NP-complete prob... 详细信息
