 Abstract: The small, low-cost and tinkering-friendly Raspberry Pi computer board has been used as the basis for a variety of distributed computing clusters built by research groups and individuals for experimental and pedagogical use. The new Raspberry Pi Zero model is smaller, consumes less power, and costs only $5.00 (when supplies are available), but lacks the built-in ethernet interface of its larger predecessors. Making a virtue of necessity, an Altera Cyclone II FPGA on an inexpensive development board can be used to provide the communication fabric for a pocket-sized Raspberry Pi Zero cluster, avoiding the need for bulky network cables and routers, and enabling experimentation with different networking architectures which may be more suited to fine-grained closely-coupled distributed computations than the usual TCP/IP over commodity ethernet. (Work in progress.)
