Parallel Sorting On A Spatial Computer, Max Orhai, Andrew P. Black
Computer Science Faculty Publications and Presentations
We describe a parallel sort for a spatial computer that requires minimal communication. We show simulations of the sort in 1 and 2 dimensions.

Patterns As Objects In Grace, Andrew P. Black, Michael Homer, James Noble, David J. Pearce, Kim B. Bruce
Computer Science Faculty Publications and Presentations
Object orientation and pattern matching are often seen as conflicting approaches to program design. Object oriented programs place type-dependent behaviour inside objects and invoke it via dynamic dispatch, while pattern matching programs place type-dependent behaviour outside data structures and invoke it via multiway conditionals (case statements). Grace is a new, dynamic, object-oriented language designed to support teaching: to this end, Grace needs to support both styles. In this paper we explain how this conflict can be resolved gracefully: by modelling patterns and cases as partial functions, reifying those functions as first-class objects, and then building up complex patterns from simpler …
