Francesco Di Renzo Physics plans and ILDG usage in Italy Francesco Di Renzo Physics plans and ILDG usage in Italy Disclaimer Disclaimer • I will refer to italian LQCD activities immediately related to ILDG. • There are many other physical projects going on, focused on a number of interesting subjects (color confinement, deconfinement transition, QCD phase diagram, connections to strings, …), not in the ILDG core business. • Other activities (e.g. INFN research project TV11 within CLS) not covered. ILDG in ILDG in Italy Italy • Part of LDG regional grid • Italian ILDG SE in Parma (StoRM Storage Resource Manager) • INFN research project ( iniziativa specifica iniziativa specifica ) ) RM22 RM22 ( (groups groups in in Rome Rome I I, , II II, , III III), ), within ETM Collaboration. 15 th th ILDG workshop ILDG workshop December 4, 2009 4, 2009 15 December

Francesco Di Renzo Physics plans and ILDG usage in Italy Francesco Di Renzo Physics plans and ILDG usage in Italy RM22 (ILDG) RM22 (ILDG) activities activities • Not big production activities in recent months (other sites within ETMC have much more powerful computers!) • Lot of Physics from Nf=2 ETMC configurations (soon widely available within ILDG): PS-mesons decays constants B k new methods and results for B-Physics semileptonic decay form factors • Configurations production scheduled: N f =4 (degenerate mass ~ 50-100 MeV) @ β =1.9 and 1.95 (a ~ 0.9 and 0.8 fm) 24 3 x 48 aim: RI-MOM renormalization for ETMC 2+1+1 action. Super(?)computers Super(?) computers in in Italy Italy • apeNEXT machines installed at the national NEXTCenter facility (Rome) are still the main resource for Lattice QCD (peak performance of about 7 TFlops) … … but some news worth mentioning! 15 th th ILDG workshop ILDG workshop December 4, 2009 4, 2009 15 December
