Description
Impact
The SYNTSPEC application benefits from the usage of large project resources, which makes possible the calculation of synthetic stellar spectra for significant wavelength ranges, which is essential for the galactic and stellar research studies. Running of the application within the Gridcom interface improved the job submission procedures and the possibilities of user interaction. The application can be submitted and analyzed by a geographically distributed group, which is especially important in the remote teaching or analysis of data.
Impact of the project:
The BalticGrid-II project has established a production-level grid, interoperable and complementary with the EGEE grid infrastructure, which provides the scientists in the Baltic States and Belarus access to critical resources, support effective research collaborations and makes possible the efficient sharing of unique instruments and data.

Conclusions and Future Work
The usage of grid infrastructures has increased significantly the synthetic stellar spectrum computation abilities, and the SYNTSPEC application has become a powerful tool for astronomers, being a good example of user friendly tool with a significant science potential. Bearing in mind the imminent start of the GAIA mission, future development of the application is planned, with a focus on making it more autonomous and time saving for scientists.
Detailed analysis
The SYNTSPEC is a very good example of an application that benefits from usage of the BalticGrid-II testbed due to the need of powerful computing resources. It calculates the normalized continuum stellar spectrum, that is used for determinations of, for example, the chemical compositions, effective temperatures and surface gravities of stars. Until now, it was used for modeling of small spectral regions; however scientific requirements increase rapidly, and so the possibility of using the grid infrastructure is a crucial to accumulate enough resources for the analysis of massive data. This is very important for the analysis of the large quantities of spectra coming from many ground observatories, and is essential for the preparation of infrastructures and procedures for the processing of data which will be produced by the European Space Agency’s GAIA space observatory (to be launched in 2011).
The special added value is the implementation of the application in the Gridcom interface on the BalticGrid- II Special Interest Groups site (http://sig.balticgrid.org). Integration with the Gridcom graphical interface makes the application usage much more intuitive for users, and enables the group work of scientists to be independent of their geographical location.

Justification for delivering demo and technical requirements (ONLY for demonstrations)
We would like to present a live demo, showing to the audience application submission within user friendly environment and interpretation of result. An internet connection RJ-45 and the place for the demo computer are required.
