HPC Technology Promotion Office, Center for Computational Science and e-systems (CCSE) of Japan Atomic Energy Agency (JAEA) is responsible for the administration of computer programs (CPs) and databases (DBs) developed in JAEA to disseminate R&D results in JAEA to the outside and improve R&D efficiency. The information of these CPs and DBs can be found using Program and Database retrieval System (PRODAS) (https://prodas.jaea.go.jp), which is developed by our team. Those in Japan can also obtain CPs and DBs in the nuclear field possessed in OECD NEA Data Bank (NEADB), Radiation Safety Information Computational Center (RSICC) in the United States, and International Atomic Energy Agency (IAEA). In this paper, the recent situation of possession and dispatch of CPs and DBs developed within JAEA and the frameworks to obtain and provide CPs and DBs in nuclear field worldwide are presented.

Research on simulation engineering for nuclear applications has been performed at Center for Computational Science & e-Systems, Japan Atomic Energy Agency (CCSE/JAEA). We established the committee which does research evaluation and advice as the help of the research and development. This report describes the result of the evaluation of research on simulation engineering performed at CCSE/JAEA in FY2005.

Information-Technology Based Laboratory (ITBL) project has been propelled as one of e-Japan priority policy programs. The purposes of the project are to share intellectual resources such as remote computers, programs and data in universities and institutes and to support cooperative studies among researchers, building a virtual research environment, ITBL. Japan Atomic Energy Research Institute (JAERI) has been working on installation and management of hardware and development of infrastructure software and applications. As application software, researches on quantum bioinformatics and environmental sciences are carried out. This paper presents utilization of ITBL system infra-structure software for 'Numerical Environment System' which is developed for environmental studies. More effective job executions and visualization are ex-pected by using Task Mapping Editor (TME) and AVS/ITBL, which are tools developed as infrastructure software.
study of hydrogen hydrate clathrates for hydrogen storage within the ITBL environmentSluiter, M. H. F.*; Belosludov, R. V.*; Jain, A.*; Belosludov, V. R.*; Adachi, Hitoshi*; Kawazoe, Yoshiyuki*; Higuchi, Kenji; Otani, Takayuki

Recently, for the first time a hydrate clathrate was discovered with hydrogen. Aside from the great technological promise that is inherent in storing hydorogen at high density at modest pressures, there is great scientefic interest as this would constitute the first hydrate clathrate with multiple guest molecules per cage. The multiple cage occupancy is controversial, and reproducibility of the experiments has been questioned. Therefore in this study we try to illucidate the remarkable stability of the hydrogen hydrate clathrate, and determine the thermodynamically most favored cage occpancy using highly accrate 
computer simulations in a parameter survey. To carry out these extraordinary demanding computations a distributed code has been developed using the SuperSINET with the ITBL software as the top-layer.

Prototype of the middleware for Grid project promoted by national institutes in Japan has been developed. Key technologies that are indispensable for construction of virtual organization were already implemented onto the prototype of middleware and examined in practical computer/network system from a view point of availability. In addition several kinds of scientific applications are being executed on the prototype system. It seems that successful result in the implementation of those technologies such as security infrastructure, component programming and collaborative visualization in practical computer/network systems means significant progress in Science Grid in Japan.

An experimental application of Grid computing was executed in ITBL project promoted by six member institutes of MEXT. Key technologies that are indispensable for construction of virtual organization were implemented onto ITBL Middleware and examined in the experiment from a view point of availability. It seems that successful result in the implementation and examination of those technologies such as security infrastructure, component programming and collaborative visualization in practical computer/network systems means significant progress in Science Grid in Japan.

SCore system has been developed to provide flat computing infrastructure for parallel computing without awareness of each compute host in a PC cluster system. An SCore cluster system can be handled as a single computer. MPICH-SCore, which is an MPI library in SCore, is not available across multiple SCore cluster systems as well as multiple platforms. We have implemented an MPI communication library, Stampi in SCore cluster system to enable MPI communication between SCore cluster systems and measured communication performance of the library using SCore cluster systems.
