A Lattice Model for the Optimization of Communication in Parallel Algorithms

Authors: Sven de Smet

This paper describes a unified model for the optimization of communication in parallel algorithms and architectures. Based on a property that provides a unified view of locality in space and time, an algorithm is constructed that generates a parallel architecture that is optimized for communication for a given computation. The optimization algorithm is constructed using the lattice algebraic properties of congruence relations and is therefor applicable in a general context. An application to a bio-informatics algorithm demonstrates the value of the model and optimization algorithm.

Comments: 12 pages. This paper is a slightly modified version of a draft paper that was submitted to ParCo 2011 and is very preliminary. Since I do not have the resources to complete this paper by increasing its clarity, extending the experimental evaluation and adding a section on related work, I'm making it available so that it may be useful to others.
