Description
Numerical simulations of QCD formulated on the lattice (LQCD) require a huge amount
of computational resources. Grid technologies can help to improve exploitation of
these precious resources, e.g. by sharing the produced data on a global level. The
International Lattice DataGrid (ILDG) has been founded to define the required
standards needed for a grid infrastructure to be used for research on lattice QCD. In
this talk we will discuss the requirements, problems, solutions and open issues
related to putting a grid-of-grids into operation. We will in particular report on
the implementation of a standard for metadata and a metadata catalogue. Furthermore,
we will consider issues related to file catalogues, data management and access
control. In this contribution we will focus on the experience of operating a
LCG2-based grid infrastructure used by LQCD research groups in Europe.
