Abstract [en]

By connecting many simple general-purpose RISC CPUs with a Network-on-Chip memory system, the Epiphany co-processor architecture provides promising power-efficiency. This thesis presents ParallErlang, a modified Erlang Runtime System, capable of running some actors on the Epiphany co-processor. The complete lack of caches is dealt with by introducing an Epiphany backend to the HiPE Erlang compiler, and a software implementation of an instruction cache. Memory system inconsistency is dealt with by constructing a sequence of instructions with fence semantics, and having HiPE inline this "fence" where required. Finally, performance and power-efficiency is measured and evaluated, and while no benchmark show any improvement over an ARM Coretex-A9 CPU, benchmarks also indicate that should overheads be possible to eliminate, an improvement of over two orders of magnitude could be possible, bringing power-efficiency superior to the ARM.
