Developing high-performance parallel visualization server can give full play to the advantages of resources in high-performance computer, provide efficient parallel visualization service based on high-performance computer, and overcome the low efficiency of after-treatment model in the tra-ditional visualization way. This thesis introduces the structure and functions of the high-perfor- mance parallel visualization server;focuses on the algorithm of resource allocation and optimizing in the high-performance parallel visualization server. The algorithm can allocate compute nodes with the resources of the high-performance computer for the scientific computation visualization application efficiently, and have a strong self-adapted ability. The result of the experiment indicates that our algorithm completed the allocation of computing resources efficiently according to the characteristics of big data scientific computation visualization tasks, and improved the efficiency of scientific computation visualization very much compared to the traditional visualization model.
