Abstract: Multi-stage and plural process of mineralization, multivariable metallogenetic factors, multidimensional and multiresolution of ore-forming space, bring about the complexity in simulating ore-forming process, and difficulty to simulate it in real-time by one computer. Under the Ethernet with PC cluster, it is practicable to simulate the mineralization of 3D by means of memory sharing and task distribution of parallel computing. The prototype system, based on Client-Server, plug-in and algorithmization, is effective in image processing and with linear speed-ups, tested by 8 PCs.
