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.

Super(?) Super(?)computers 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!

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 Bk new methods and results for B-Physics semileptonic decay form factors

• Configurations production scheduled:

Nf=4 (degenerate mass ~ 50-100 MeV) @β=1.9 and 1.95 (a ~ 0.9 and 0.8 fm) 243x48 aim: RI-MOM renormalization for ETMC 2+1+1 action.

New HPC New HPC italian initiatives italian initiatives APE APE group group in in Rome Rome

• (Long term) PetApe: based on custom ApOtto custom multi-tile processor + 3DTorus
• ApeNet+: commercial computing nodes connected via APE-like torus

evolution of ApeNet, DNP network processor based on FPGA hybrid architecture (CPU+GPU) (prototypes: card 1Q 2010, system 4Q 2010)

AURORA project AURORA project

• INFN (Ferrara, Milan Bicocca, Parma) + Univ. Padova
• Univ. Trento + ECT* + IASMA + ATREP (substantial funding from Trento local government)

industry (EUROTECH + Intel)

• Intel last generation processors (Nehalem, Westmere, …) + 3DTorus network FPGA-based

All design taylored to scalability to PetaFlop

• O(20) Tflops prototype in first half 2010
• O(100) Tflops rack scheduled for 2011
