%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.
