Steering High-Performance Parallel Programs: a Case Study
Authors: Love, P. J., Martin, Jeremy M. R.
Computational steering is the ability to visualise the data from a computation in progress and to modify the future behaviour of the computation in response to this. It is often perceived as being something very difficult to implement, especially for parallel computations. However, given a good visualisation environment, we have found that this is not necessarily the case. We have sought to dispel this myth, using a very simple model which makes it easy to 'wire-up' an existing MPI parallel program for steering. New insights may quickly be gained by continually monitoring and guiding the progress of computational simulations, that were perhaps previously analysed only in their final state.
