So far I've focused mostly on HPC use-cases---generally simulations on a variety of data structures: (multi-dimensional) arrays, graphs, meshes, etc. The more interesting cases are distributed pointer data structures, and our hope is that supporting these will help Regent generalize well to non-HPC use-cases as well.

Here are a couple representative examples of what we've done so far:

* A hydrodynamics simulation on a 2D unstructured mesh (a pointer data structure): https://github.com/StanfordLegion/legion/blob/master/languag...

* A simulation of an electric circuit (a graph): https://github.com/StanfordLegion/legion/blob/master/languag...

(We have smaller toy examples that work with linked lists, trees, matrices, etc.: https://github.com/StanfordLegion/legion/tree/master/languag...)

+1 for more varied examples
