In order to deploy existing scientific or business applications on a service-based Grid, these legacy code programs have to be transformed into Grid services. GEMLCA (Grid Execution Management for Legacy Code Architecture) represents a solution to make available and execute legacy applications through an OGSI Grid service without re-engineering the original code. GEMLCA is a client front-end OGSI Grid service layer that offers a number of interfaces to submit and check the status of computational jobs, and get the results back. This paper describes the GEMLCA architecture and life-cycle, and outlines the current state of implementation.
