1. Introduction to the ILDG session
T. Yoshie
CCS, Tsukuba
March
Tsukuba WS “Perspectives on Light Quark Simulations through machine, algorithm and ILDG

2. Status and Statistics proposed in 2001
Two working groups and ILDG board
Metadata WG to design QCDml
Middleware WG to standardize interface among RGs and develop system
Board to supervise WGs and coordinate activities
1st stage construction completed in 2007
already used
to open data to the public
to share data within collaboration

3. ILDG continues stable operations

Statistics of the ILDG as of June 2008
ILDG continues stable operations
ILDG is becoming an important infrastructure
QCDml satisfies all current community requirement
Middleware is working as designed
