Description
Justification for delivering demo and/or technical requirements (for demos)
A demo offers possibility to reach much broader audience than during ordinary session. No special requirements is required -- a tv screen and fast internet connection for live demonstration
Conclusions and Future Work
The Grid web portal for chemists has been developed to fulfill community needs especially coming from users newly adapting to the Grid. Although the number of software packages supported by the portal is still limited, the collection of computational methods provided by the above software suites allows studies of a variety of molecular properties at various levels of accuracy. Nevertheless, our future work will focus on the adoption of other packages to extend the available portfolio, as well asthe integration of the portal with national grid infrastructures for the benefit of their users.
Detailed analysis
Existing web portals focus mainly on tasks, which simplify job management on the Grid. Although this is very important, this part of portal functionality is not sufficient for scientists accustomed to GUI environments supporting their research conduction. Our solution, in contrast to other existing web portals, is “user centric” instead of “grid centric”. Therefore, it provides tools facilitating research conduction and “hides” the existing grid infrastructure from the user as much as possible. The tools adopted in the portal, based on ViroLab Project technology together with Google Web Toolkit library, allow for easy planning, development and execution of complicated computational experiments without being distracted by the grid technology. Currently users can execute and modify the existing experiments allowing execution of Gaussian, Turbomole and GAMESS US packages including a variety of computational chemistry methods. Other tools integrated in the portal allow an analysis of the results of computational experiment(s) (energy for example) and their visualization. Particular experiment results can be displayed via external software.
Impact
The development of grid web portal for chemists is a next step towards better community satisfaction. As it focuses on computational experiments in chemistry rather then job management only, we expect high interest in it, coming mainly from new users adopting the EGEE Grid. The availability of the portal will not only avoid new users’ disappointment but what is more important will drastically shorten the time needed for the adoption of grid computing to particular computational problems in chemistry. Although the current version is limited to the several first principles codes only, most of the important chemistry tasks like chemical reaction paths, potential energy surfaces, or even ab initio molecular dynamics studies, can be easily performed onthe EGEE infrastructure.
