  The energy-efficient Adapteva Epiphany architecture exhibits massive
many-core scalability in a physically compact 2D array of RISC cores with a
fast network-on-chip (NoC). With fully divergent cores capable of MIMD
execution, the physical topology and memory-mapped capabilities of the core and
network translate well to partitioned global address space (PGAS) parallel
programming models. Following an investigation into the use of two-sided
communication using threaded MPI, one-sided communication using SHMEM is being
explored. Here we present work in progress on the development of an OpenSHMEM
1.2 implementation for the Epiphany architecture.
