Enterprises are looking at Grid computing as a technology of enormous potential. One such issue is the issue of Grid application migration, where legacy applications are migrated to the Grid environment. The Grid Application Migration Framework (GAMF), is an attempt to provide a systematic approach for handling the migration process. The framework consists of three independently deployable components: Grid Code Analyzer (GCA), Grid Task Generator (GTG), and Grid Simulator (GS). The GCA component analyzes the different applications and generates a Directed Acyclic Graph (DAG) based on the information obtained from analysis. The DAG is based on both static and runtime information available from application profiling. The DAG information is then analyzed and Grid tasks are generated based on different DAG reducing and clustering algorithms. The simulator takes the generated DAG as input and provides and analyzes the application performance with respect to Grid infrastructure and policies.
