Europe, and the German D-Grid (http://www.d-grid.org).
Together, these projects cover large parts of the world (see Figure 3.8 )
and a wide variety of hardware systems. In particular, infrastructures like
EGEE and OSG primarily federate centers with clusters of commodity
PCs whereas DEISA and TeraGrid federate supercomputing centers.
However, the technologies deployed by the different projects vary widely
exposing different interfaces and protocols and offer different service
characteristics.
The goal of the Open Grid Forum (OGF, http://www.ogf.org) is to har-
monize these different interfaces and protocols and develop standards that
will allow interoperable, seamlessly accessible services. One notable effort
in this organization where all of the above-mentioned projects work
together is the Grid Interoperation Now (GIN) [22] group. Through this
framework, the mentioned infrastructures work to make their systems
interoperate with one another through best practices and common rules.
GIN does not intend to dei ne standards but instead to provide the ground-
work for future standardization performed in other groups of OGF. Already
this has led to seamless interoperation between OSG and EGEE, allowing
jobs to freely migrate between the infrastructures as well as seamless data
access using a single sign-on. Similar efforts are currently ongoing with
NAREGI, DEISA, and NDGF. As part of the OGF GIN effort, a common
service discovery index of nine major grid infrastructures worldwide has
been created, allowing users to discover the different services available
