A Distributed Approach for Structured Resource Discovery on Grid

We present a distributed approach for grid resource discovery, which combines a structured view of resources (single machines, homogeneous and heterogeneous clusters) at the physical organization (PO) level with a super-peer network connecting the various POs. The proposed architecture is modular and independent of the particular grid middleware. After a general description, we present some implementation aspects which refer to the Globus Toolkit 4 as grid middleware and to the JXTA platform to set-up the super-peer network. The system is particularly suitable for discovering resources for structured parallel applications on very large grids.
