We explore the All-to-All Comparison problem on large data sets with a distributed computational resource. This has applications in biological modeling and image analysis. The key to high performance is to distribute data and schedule computations in such a way that computations are scheduled where the data already lies. Unlike the highly successful Map-Reduce framework (Hadoop) which partitions the data set, we must distribute the data so that every pair appears on at least one machine. This could easily be achieved by placing every object on every machine, but the data is large, so we wish to minimize the amount of data replication. We prove that this problem can be solved optimally using Finite Projective Planes and Affine Planes.
