With machine learning being applied to increasingly varied domains, the computational needs of researchers have increased proportionately. Hobbyists, researchers and universities are turning to building their own cluster computers to meet their high performance compute needs. These clusters are typically highly efficient, low cost ARM based platforms consisting of between 4 and 8 nodes. In this paper, we present PHINEAS: Parallel Heterogeneous INdigenous Embedded ARM System, a parallel compute

We describe the hardware components of the cluster, the software stack installed on each node and a host of common benchmark algorithms and their results. The results show that the cluster meets the stringent latency requirements of embedded systems. We further describe how the on-board GPU's OpenGL ES 2.0 programming model can be used to implement tasks such as image convolution and neural network inference which are common in intelligent embedded systems. Parallelisation of compute tasks across multiple GPUs is discussed as a method to combine the advantages of distributed and heterogeneous computing.
