Description
The D-Grid initiative, following similar programs in the USA and the UK,
shall help to set up a nationwide German Grid infrastructure. Within work
package 3 of the HEP community Grid distributed analysis tools under usage
of grid resources shall be developed.
A starting point is the analysis framework ROOT. A set of abstract ROOT classes
(TGrid ...) provides the user interface to enable Grid access directly from within
ROOT. A concrete implementation exists already for the ALICE Grid Environment AliEn.
We are developing an interface to the common HEP Grid middleware gLite. This
includes querying the gLite File Catalogue, access to individual files, job
submission, getting the job status, and retrieving job output. Extensive tests will
be done within the gLite testbed of the DECH VO (EGEE).
First interactive analysis environments have been set up at single sites using
the Parallel ROOT Facility, PROOF. This shall be extended towards several sites
using existing Grid Middleware with the aim of a dynamic generation of Grid
Analysis Clusters.
The current status of the work is presented in the poster.
