Abstract In order to process the massive distributed data, control the agricultural facilities intelligently and improve the production efficiency, a parallel Dirichlet Process Mixture Model (DPMM) clustering method is proposed in this paper based on Spark, which is a memory computing framework. Firstly, the prediction model of skylight opening degree in greenhouse is obtained by training the agricultural environmental and facilities data. Secondly, the model is used to predict the greenhouse skylight opening degree. Thirdly, by compared experiments, both the feasibility and the efficiency of the proposed parallel clustering are verified, the prediction accuracy is also calculated. The experimental results show that the proposed approach has higher efficiency and accuracy.
