Laboratory for Electronic Design Automation (LEDA), in the Faculty of Electronic Engineering of the University of Niš is responsible for AEGIS03-ELEF-LEDA site. The site started with four worker nodes (P4 on 2.4GHz with 512MB RAM and 80GB storage capacity) and UI, CE, MON and SE services. The site supports aegis, seegrid, dteam, env.see-grid-sci.eu, seismo.see-grid-sci.eu, meteo.see-grid-sci.eu and ops.vo.egee-see.org virtual organizations. MPI-based parallel applications are supported. Site capacities will soon be extended to 64 processor cores (Intel Xeon QuadCore processors on 2.4GHz, with 12MB L2 cache and 4GB RAM per node), and site storage capacity will be 2TB.
