| Studying supernova shock waves |

The compute speed of the VH-1 hydrodynamics code used to study the dynamics
of the stalled supernova shock wave in three dimensions in the TSI project. |

This plot shown in the graph left represents a "weak" scaling study, in which the computational
workload (i.e. the size of the problem) is increased along with the number of processors. The
test problem that was used involves a strong shock wave propagating across the volume of a cartesian box.

A typical TSI run uses of the order of one billion zones, and a full time update can be performed
in roughly 1s on either of the new Cray platforms.
