CPU resources: total allocations 5-6M hrs NASA Ames Marenostrum (Barcelona) Julich (Germany) LRZ (Germany) NERSC Friday, December 17, 2010
Main projects: • Bolshoi: 250Mpc, 8G particles, 1kpc resolution, N-body ART: Magellanic Clouds + • bigBolshoi/MultiDark: 1Gpc, 8G particles, 5kpc: Milky Way-size halos + • All 1e15Msun clusters re-simulated with 8 times smaller mass, full hydro+SF, GADGET • Local Volumes: hundreds of MW-halos. Small halos complete 10km/s, N-body ART • Galaxy Formation: hydro runs of individual galaxies. ART, resolution down to 10pc 100-200 Tb/year of high-res models Friday, December 17, 2010

• Simulations should be made easily accessible for different groups: catalogs and raw data • MultiDark database at AIP is a great start • Few data centers (in US and in Europe) are needed • Need to have support - personnel and hardware - for the centers Friday, December 17, 2010
