Dynamic Visualization of Computtations on the Internet

We present the design of a visualization tool which can be incorporated in parallel/ distributed code to track computational parameters with respect to convergence and the distribution of the work remaining for the parallel processes. We describe its functionality, algorithms and implementation in Java, as it is applied to a package for multivariate integration. Implementation aspects include message passing and control ow in its interaction with the application code. The approach is mainly asynchronous and based on multi-threading.
