VIWOB: an interactive programming environment for distributed simulations

VIWOB is an integrated environment for programming and executing simulations interactively on distributed computational resources. A visual dataflow oriented language allows a user to assemble application programs by simply connecting processing nodes. Single nodes can be described by subgraphs (modules) permitting the implementation of complex programs in a hierarchical structured manner, as well as taking advantage of previously developed modules, while hierarchical ordered libraries provide convenient access to the available modules. The run-time environment will break up the application and execute the components transparently on a distributed computing facility. An abstract computational model simplifies adding new primitive modules
