This will hopefully shut up everyone complaining about
stupid things like .EXE-sizes. If not, here's another thing:
Delaunay triangulation of 976 nodes, giving 2932 edges and 1830
elements:
IBM RISC/6000, 380, 3AT with 99.3 SPECint92 and 187.2 SPECfp92:
realtime 12s
486/100, no name
realtime 22s
The price for the IBM was around $30000, for the NoName about $2000.
Running this on a P166 might be interesting.
To be fair, the triangulation is a process of the order n*n, so on
larger meshes the balance gets better for the IBM, but you get the idea.
If I just had had DJGPP when I wrote my diploma-thesis...
Who needs BC, anyway?
