Abstract: The scale of data produced by numerical simulation have reached Tb to Pb magnitude in the fields of geodynamics and climate simulation. It is very difficulty to realize real-time visualization and analysis for this massive data. Data extraction of multi-scale for space and time dimensions is able to solve it. The visualization products of high-precision need high-resolution display device, and parallel display array with a high- resolution can meet this need. Numerical simulation of geosciences, parallel abstract for massive data and high-resolution display all need to construct high-performance computer cluster. We achieved parallel abstract of multi-dimension, multi-scale and multi-resolution program for massive data based on Lagrange interpolation. At the same time, on the base of the Rockscluster system, we used the parallel compute node and the LCD display hardware to build a 4×10 parallel display array with a 52 millions resolution and 176 processors integration platform, which can be used to compute and parallel display. We successfully realized parallel abstract and displayed for massive data produced by climate model numerical simulation using this platform.

Key words: Massive data, Lagrange interpolation, Data extract, Parallel visualization
