Future generation Grid technology aims to provide transparent and easy access of remote resources to end-users. Parallel and distributed computing environments like Condor, PBS, WebDedip, load leveller, etc are now becoming Grid compliant. These environments address interoperability issues to certain extent by extending Resource Specification Language (RSL) as per their requirements. In fact, such an extension in fact restricts interoperability. In this paper, we propose an alternative mechanism that addresses the interoperability issues.
