We develop an algorithm for parallel disk sorting, whose I/O cost approaches the lower bound and that guarantees almost perfect overlap between I/O and computation. Previous algor...
The performance of services implemented in the serviceoriented knowledge grid becomes one of the most key issues that affect the development of the knowledge grid. This paper pres...
This paper presents an efficient parallel information retrieval (IR) system which provides fast information service for the Internet users on lowcost high-performance PC-NOW enviro...
A hierarchy is an arrangement of qualitative values in a tree with certain properties. Hierarchies allow to define the confusion conf(r, s) in using qualitative value r instead of ...
Data parallel compilers have long aimed to equal the performance of carefully hand-optimized parallel codes. For tightly-coupled applications based on line sweeps, this goal has b...
