Monitoring and controlling remote parallel computations using Schooner

Scientific visualization systems such as AVS have the potential to help users of parallel systems monitor and control their computations. Unfortunately, the machines most suitable for visualization systems are not the parallel systems on which the computation executes, often leading to the use of two distinct machines and the viewing of results only after the computation has completed. Here, an approach to solving this problem is presented in which AVS and a remote parallel computation are incorporated into a single metacomputation using the Schooner software interconnection system. This scheme gives the user enhanced control, including the ability to dynamically select the parallel platform to be used, monitor the progress of the computation, and modify parameters
