Abstract :
There are many legacy code applications that cannot be run in grid environment without significant modifications. To avoid reengineering of legacy code, we developed the grid execution management for legacy code architecture (GEMLCA) that enables deployment of legacy code applications as grid services. GEMLCA is an OGSI grid service layer that supports submitting jobs, getting their results and status back. Security requirements are essential to any grid application to preserve the confidentiality and integrity of data. To meet these requirements the GT3 security model was implemented in GEMLCA. The paper introduces GEMLCA and how grid security infrastructure (GSI) components have been added to GEMLCA in order to enable secure execution of jobs in grid. The paper also presents how a legacy code traffic simulator was transformed into a grid service using GEMLCA and gives some simulation results.
