To visually illustrate the impact of architecture and communication on parallel computing we created a model supercomputer in the spirit of other engineering models. Combining Raspberry Pi computers with an Nvidia TK1 the resulting machine is distinguished by it's instructional utility, asymmetric CPU and communication channel speed, and for incorporating current trends in heterogeneous supercomputing. Running Linux, the model supports major high-performance computing software environments, including OpenMP, MPI, and Nvidia's CUDA. The model architecture includes aspects of heterogeneous, supercomputers such as shared-and distributedmemory MIMD, and 192 CUDA core SIMD-like processors.
