		| Abstract: | 
		The paper presents a brief overview of the EU project DEISA, the Distributed European Infrastructure for Supercomputing Applications. We describe its
 vision, mission, objectives, infrastructure and services offered to the e-science community. The DEISA Extreme Computing Initiative for supercomputing
 applications is highlighted, and four grand-challenge projects of
 astrosciences simulations are presented: modeling of turbulent astrophysical
 flows, simulating the Local Universe, turbulent, active, and rotating stars,
 and simulating the formation of the Milky Way. |
