摘要：
In this paper, we present the use of parallel/distributed programming frameworks, MPI and OpenMP, in processing and analysis of big trajectory data. We developed a distributed application that initially performs a spatial join between big trajectory data and regions of interest, and further aggregates join results to provide analysis of movement. The solution was implemented using hybrid distributed/parallel programming model, based on MPI and OpenMP programming interfaces. The experimental evaluation in detecting the most popular places in the city, based on large-scale trajectory dataset, demonstrates the performance gains and feasibility of our approach.
