We have introduced about the framework to make the integration of large and complicated simulation such as a proof strength simulation of nuclear power plants and a control simulation of nuclear fusion plasma which codes are installed to distributed computers. We able to carry out detailed simulations by integrating various simulation methods with development of simulation technique. However it becomes a burden to control the integration of each simulation code for researchers. We have noticed that the execution scenarios of each code in cooperated simulation are roughly categorized to workflow type, pipeline type, and conditional branch type. Then we have developed the framework in which just write those patterns in a configuration file and achieve the cooperative execution of element codes without substantial modification of simulation codes.

With the improvement in the performance of supercomputers, numerical simulations have become complex and the simulation results have become large-scale. It has made the interpretation of simulation results difficult. Therefore, we propose a spatio-temporal visualization system "spatio-temporal map" for interpreting the time-series simulation results. The spatio-temporal map is an information visualization technique useful for specifying the feature area from simulation and measurement results. In the map, the change of a physical quantity is allocated in two-dimensional space with spatial and temporal information in each dimension. In this paper, we demonstrate the effectiveness of the proposed method by applying it to the large scale simulation results.

We research and develop IMAGINE as the dose calculation system, which can calculate the dose distribution in the patient body very fast and with high precision by a super parallel calculation, for the contribution to QoS of the radiation therapy and the development of the eading-edge treatment technology. When IMAGINE system will be actually operated, it is anticipated that IMAGINE system accepts the large amount of requests of the dose calculation from several radiotherapy facilities at the same time. So, we entertained that the dose calculation was distributed by the gridization of IMAGINE system and the waiting time of its was minimized. In this article, we introduce the problem about the gridization of IMAGINE system, the solution to it and the method to easily enable the gridization of the application without the programming skill.

At the Japanese national project "Development and Applications of Advanced High-Performance Supercomputer", we have developed an application programming interface for a using grid computing environment in order to shift the grid-enabled application developed in ITBL project to the next generation national grid infrastructure. We have developed the prototype of API by analyzing how grid-enabled applications in ITBL project use the grid computing environment. Using this prototype enables to develop grid-enabled applications easily, to use different grid environments without changing applications and to interoperate different grid environments without changing grid middleware.

In the present paper, an interoperable system which seamlessly connected two GRIDs was introduced. GRID is originally designed to shared the computational or experimental resources, which were geographically distributed. However, several GRID middleware, which enabled GRID computing, were developed with their own policy. Therefore, they loses the compatibility with each other. In line with this background, we develop GRID inteopreable system. As a result, we succeeded to connect ITBL to UNICORE, which isorganized by HRLS (The High Performance Computing Center Stuttgart, Germany).

ITBL (Information Technology Based Laboratory) project is promoted under the "e-Japan national priority program" by six research institutions. The project aims to construct a virtual laboratory which aid collaborative studies amongst researchers by allowing for sharing of intellectual properties and resources such as supercomputer hardware, software, data, etc. In order to realize this virtual laboratory environment, the Japan Atomic Energy Research Institute is developing an ITBL system infrastructure software system. Some of the highlighted functions offered by the ITBL infrastructure are: authentication for connecting to the supercomputers, parallel and distributed communication, job execution on the connected supercomputers, and formation of communities for aiding communication amongst researchers. In this passage, besides the introduction of the ITBL infrastructure, a brief introduction of the Quantum Bioinformatics and the Numerical Environmental Systems will be given as examples of the applications developed on the ITBL infrastructure.
