this paper we present a generic approach TGEX for analyzing and executing unstructured problems. It separates the specification of a computational problem from the control of the parallel execution. A computational problem is first partitioned in terms of a computation task graph which serves as a machine-independent representation of the parallel program. This allows fast and accurate performance simulation with the Pamela tool and efficient parallel execution. Experimental results of using Pamela and TGEX for scalability analysis and parallel execution of unstructured problems are reported.
