Summary
During the last 4 years production level grid infrastructures
emerged and spawned the scientific community all over the
world. These infrastructures have given a broad grid service
portfolio related to job execution, grid resource information
and data storage. While the different grid resources can
usually contact each other at network level, there was little
emphasis put on e.g. transparent job transfer on any grid
middleware developers's side.
Interoperability is a new emerging area that focuses on how
different services of different grid systems can contact each
other and exchange useful job, resource information as well
as data with each other.
Interoperability can be investigated at both technical and
organizational levels: in thechnical terms grid systems
should enable multiple communication protocols used by
contemporary grid systems for a single service. On the other
hand for grids that use different data representations there
should be an information transfer possibility that acts as a
bridge between the middleware's internal data
representation and the externally expected data formats.
This task can be done on a special infrastructural element,
called grid gateways.
On the organizational level grid systems should take steps
toward currently existing standards, and new standards
should also be established.
