A web-based metacomputing problem-solving environment for complex applications

In this paper a kernel of Problem Solving Environment aimed at managing complex chemical meta-applications based upon an a priori simulation of molecular structure and dynamics has been presented. By considering as a case study the simulation of a molecular beam experiment (SIMBEX), a metacomputing environment able to facilitate the SIMBEX execution through the Web has been designed. This choice is due to the rapid and impressive growth of Internet, Java and, Web technologies. The current work focus on the architectural aspects of the implemented environment.
