Abstract

This paper presents a parallel algorithm for solving grounded range search in associative-function mode using the BSP-like Coarse Grained Multicomputer (CGM). Given a set S of n weighted points in the plane, the algorithm requires O(1) communication rounds (h-relations with h = O(n/p)), O((n/p) log n) local computation, and O(n/p) memory per processor (n/p 驴 p), to solve m = O(n) grounded range search problems. The result implies new or improved solutions to a number of other geometric applications including d-dimensional range search, quadrant search, interval intersection, and chromatic range queries.
