  This paper reports the implementation and performance evaluation of the
OpenSHMEM 1.3 specification for the Adapteva Epiphany architecture within the
Parallella single-board computer. The Epiphany architecture exhibits massive
many-core scalability with a physically compact 2D array of RISC CPU cores and
a fast network-on-chip (NoC). While fully capable of MPMD execution, the
physical topology and memory-mapped capabilities of the core and network
translate well to Partitioned Global Address Space (PGAS) programming models
and SPMD execution with SHMEM.
