Among various areas in this field, utilizing the computers in the research of computational chemistry that requires complex computation and simulation of the high capacity data is very important. Computational chemistry can be summarized as a field of chemistry handling the problems of theoretical chemistry utilizing the computation methods using the computers in short. High performance computers and computational chemistry tools for processing and analyzing the data are essential for both theoretical and experimental researchers in the field of computational chemistry. The importance of the computational science affects not only the chemistry but also material science and biology. As the quality of the outcome of the research in any area depends on the level of understanding of the molecular structures and functions, proper computing resources (hardware, analysis tools, network, etc), i.e. cyberinfrastructure have to be deployed in order to conduct the successful research. This paper is to survey and analyze the most popular type of tools among the various computational chemistry tools through the investigation of the web sites in biology and chemistry that provide the cyber-infrastructure based services in other countries. For this purpose, 1) world well-known web sites in biology and chemistry areas such as GridChem, CICC, and NBCR were investigated, 2) papers published using the investigated web sites were collected, 3) the status of the usage of the computational chemistry tools shown in the papers were reviewed, 4) and the most widely used computational chemistry tools based on this research will be implemented on the KISTI’s cyber-infrastructure to improve the efficiency of the research by providing the system to the researchers in the field of computation chemistry.
