| GriPhyN/iVDGL -- Toolkits |
| |
The main goal of the GriPhyN researchers is to develop the
Virtual
Data Toolkit (VDT), a set of software containing basic
elements to construct the first Global Petascale Virtual Grid.
The virtual data concept aims to unify the view of data in the
distributed Grid environment. It will not matter if the data is raw
or processed, or if it was generated from an hadron collider experiment
or a gravitational-wave detector. The virtual Grid will enable data
access and archival at nodes distributed around the globe while storing
meta-data which make the data self-describing. The
VDT developed by
GriPhyN will be deployed on the Grid to directly manage these
fundamental virtual data objects instead of complex data pipelines.
For instance, in the case of LIGO, the VDT will be capable of executing
deep searches for gravitational waves using many machines distributed
around the world, while making the results available to the
scientists in a transparent fashion. Once deployed, the Grid tools
currently under development will significantly enhance scientists'
ability to carry out the necessary analysis of the data.

The VDT
contains two types of software:
- The Fundamental Grid Software including
Globus,
Condor and
GDMP.
- The Virtual Data Software developed by the Griphyn project to work with
virtual data, such as the Virtual Data System.
See also the
Facilities web site for more information about hardware
and operating systems supported by the VDT,
for reasons of testing, benchmarking, or development.
