The Information-Technology-Based Laboratory (ITBL) project aims to construct a virtual research environment which shares intellectual resources such as the super computers by the grid computing, softwares and data in Japan and supports joint researches at a distance. In the project, two visualization systems: the PATRAS/ITBL and the AVS/ITBL have been developed. The feature of the PATRAS/ITBL is the collaborative, real-time visualization of data resulting from an execution of numerical simulations. The AVS/ITBL visualization system enables remote postprocessing visualization of any data stored on any supercomputer located in the ITBL network. The global structure and technologies of these systems are presented.

Progress of large scale scientific simulation environment in JAERI is briefly described. The expansion of fusion simulation science have been played a key role in the increasing performances of super computers and computer network system in JAERI. Both scalar parallel and vector parallel computer systems are now working in Naka and Tokai sites respectively and, particle and fluid simulation codes developed under the fusion simulation project, NEXT, are running on each system. The storage grid system has been also successfully developed for the effective visualization analysis by remote users. Fusion research is going to enter the new phase of ITER, and the need for the super computer system with higher performance are increasing more than as ever along with the development of reliable simulation models.

The Information-Technology-Based Laboratory (ITBL) project aims to build a virtual research environment for sharing intellectual resources such as remote computers, programs and data in research institutions and for supporting cooperative studies among researchers throughout Japan. The ITBL infrastructure software forms the basis of its ITBL framework. The application visualization system (AVS)/ITBL is one of core visualization systems on the ITBL system infrastructure software and has been developed based on the existing commercial visualization tool AVS/Express. The AVS/ITBL visualization system enables remote postprocessing visualization of any data stored on any supercomputer located in the ITBL network through Web browsers. In addition, a collaborative visualization function, which refers to researchers in remote locations simultaneously accessing and monitoring the same visualized image, has been developed based on the AVS/ITBL. The global structure as well as the performance of the AVS/ITBL is presented.

Visualization and analysis of extreme scale data are important issues in the next generation Exa-scale simulations. In order to resolve this issue, a remote visualization system has been developed based on the particle-based volume rendering technique. The system connects a supercomputer and a PC via a Client/Server type distributed processing model. Extreme scale data is converted to small particle data via massively parallel data processing on a supercomputer, and the particle data is transferred and rendered on a PC. In this talk, we discuss the performance of remote visualization using the K-computer.
