Abstract
En 中文
Stellar Astrophysics and in particular stellar evolutionary computations are extremely important to face a wealth of astrophysical problems, but they are also extremely demanding in terms of computing power and data storage. The Bag of Stellar Tracks and Isochrones (BaSTI) database is a theoretical astrophysical catalogue that collects fundamental data sets involving stars formation and evolution. To create this database it is necessary to run a large number of stellar evolutionary computations. The Grid technology seems to be a promising answer to data storage and processing needs of the BaSTI catalogue. In the framework of the EGEE Grid infrastructure, we managed to run a number of experiments aimed at designing and defining an application specific environment for the stellar simulation software and its interaction with the BaSTI database. Our successful implementation demonstrates that the gridification of stellar evolution code is not only possible but also even extremely convenient in terms of data processing speed and data sharing, and it can be a valuable instrument to support Astrophysical research.
