1. C.I.R.A. Italian Aerospace Research Center

2. CIRA in brief CIRA is a no-profit shareholding Consortium. The main shareholders are ASI (Italian Space Agency 47%), CNR (National Research Council 5%), Regione Campania (16%) and the main italian aerospace industries (32%) CIRA operates according to the guidelines provided by the Ministry of Education, University and Research (MIUR) CIRA mission is defined by the Italian Aerospace Research Programme (PRO.R.A.) Yearly operation cost partly is covered by government contribution Currently 350 employees (about 250 are researchers and technical people)

3. CIRA’s istitutional aim To realize Excellence Centers, which shall integrate Research Capabilities with the Large Fluid dynamic Facilities and Technological Laboratories in several main technologies areas; To identify Scientific Objectives and develop Basic Research in synergy with the National and International Scientific Community; To act as a partner of the Scientific Community and Industry; To provide technical assistance to public Authorities for qualification and regulations.

4. Areas of Competence Guidance Systems Aerodynamics, Icing and Aeroacustics Advanced Materials Computer Science Adaptronics Aerothermodynamics and Thermostruct. Space Propulsion

5. CFD TOOLS and SKILLS • Boundary Elements Method (BEM) for potential flows • EULER solvers for non-viscous rotational flows • BL, TLNS, RANS, U-RANS for viscous flows • LES, DNS for direct simulation of turbulent flows • Surface/Domain modellers, Grid generators • Direct/iterative linear system solvers and convergence acceleration techniques (multigrid, residual smoothing, etc.) • Flow Visualizers • Post-processors for analysis and evaluation of flow solutions About 50 researchers involved

6. CIRA Supercomputing activities • Vector/parallel coding and numerical optimization • Management and interpretation of data from heterogeneous systems • (numerical models, experimental facilities, observation systems, etc.)

7. Environmental Activities at CIRA CIRA and ASI have coordinated the development of the “Italian Position Paper on the Global Monitoring for Environment and Security Programme (GMES)” providing UE and ESA with the Italian capabilities and requirements CIRA is member of the CMCC consortium (EuroMediterranean Center for Climate Changing), a supercomputing center devoted to national environmental monitoring approved and funded by the Italian Ministry for Research (MIUR). Computer simulation of Sarno disaster event (1998, 147 victims)

8. CIRA activities in CMCC Project "… the safeguard of the health and the environment, are fundamental reference goals in the above strategic projects.... “ “…Particular attention must be given to the expansion and the development of an efficient and effective net of scientific and technical services, for the environmental monitoring, the hydro geological risk , the climate monitoring and the interventions for the mitigation of the harmful effects, the health's safeguard…” (From the 2002-2004 Italian Research Programme) Line 1: GRID Technologies and applications GRID Computing Applications Line 2: Numerical Applications Line 7: Training, Documentation & Dissemination Documentation, ISV&V Activities Training Numerical optimization Line 8: Operations Participation at supercomputing management activities Line 5: Evaluation & Diagnostics of impacts Hydrogeological and meteorological local modelling

9. Environmental Activities at CIRA CIRA signed an agreement with the Japanese Earth Simulator Center/JAMSTEC to cooperate on hydrogeological (landslides, floods, etc.) and meteo local phenomena • Agreement topics: • Development of common • research activities • Training and exchanging • of researchers

10. Preliminary research activities at ESC • Two CIRA researchers worked 6 months at ESC. They will spend there two months before the end of 2005. • Studies about Earth Simulator Computer : • parallel-vector optimization • execution environment • Analysis of Boundary Conditions (theoretical and numerical) in an atmospheric limited area model • Code analysis of Global Cloud Resolving Model (GCRM)regional version • Studies about numerical and physical schemes of GCRM • Sensitivity studies with GCRM on mesoscale atmospherical phenomena (winter test-case)

14. Earth Simulator (ES) System • Based on NEX SX/6, ES currently is the 4th in the top500 list (www.top500.org). • FEATURES: • Vectorial SM-MIMD • 640 nodes (8 CPUs per node, 5120 CPUs) • 8 Gflops per CPU of peak performance (8*8*640=41 Tflops total) • 10 TB of main memory

15. CIRA Interests in COSMO According to CIRA background, main interests are in Numerical and Physical Modelling (WG2 and WG3) Example of possible contribution activities for the next year (after our participation to this meeting) : WG2 -Collaboration in testing of different physical interfaces in LM_Z -Contribution to R-K case studies -Contribution to evaluation of overall performances of LM_Z WG3 -Parameters tuning for validation of new code developments (e.g. convection- turbulence schemes) -Performing sensitivity studies in order to investigate model deficiencies in the precipitation forecast Available manpower for 2006: 2 FTE CIRA contribution (including other possible activities) will be coordinated and discussed with Italian representatives in COSMO CIRA will request to the COSMO STC (via UGM) the LM code
