%X 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
   \[rs]wire\-up\[rs] 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.
