Abstract. In this paper, we present a fast algorithm to answer rangesum queries in OLAP data cubes. Our algorithm supports constanttime queries while maintaining sub-linear time up...
Building distributed applications for data centers is hard. CamCube explores whether replacing the traditional switchbased network with a directly connected topology makes it easi...
