HotSpot 2D heat equation

Straightforward port of the OpenMP implementation. Uses explicit indexing. The number of iterations to run is also given in the input data sets - these are currently all 360.

This is a fairly trivial two-dimensional rank-1 stencil, although with some unusual edge conditions. Performance in Futhark is OK.

Visualisation with PyGame

Run make to compile what needs to be compiled. Then make run to run with a standard size. Use the mouse to draw heat sources, scroll the mouse to change intensity before you draw, then press Space to run. You can use Space to toggle between drawing more heat sources and continuing the simulation.

Most of the parameters (such as ambient temperature and chip properties) are hardcoded in the Futhark program.
