This repository includes\nthe *ARL OpenSHMEM for Epiphany* implementation for optimized one-sided\ncommunication, atomic, and collective operations for the\n[Adapteva](http://adapteva.com) Epiphany microarchitecture on the [Parallella\nboard](http://parallella.org) (see [./src](./src)). Also included are\nmicrobenchmarks (see [./example](./example)) and test codes (see\n[./test](./test)). These codes require the COPRTHR-2 SDK. The library may be\nused without COPRTHR-2 and has been tested with the Parabuntu 2016.11.1\nrelease.\n\nThe OpenSHMEM implementation is based on the [OpenSHMEM 1.4\nSpecification](http://openshmem.org/site/sites/default/site\\_files/OpenSHMEM-1.4.pdf)\n\nThe software was developed at the US Army Research Laboratory, Computational\nSciences Division, Computing Architectures Branch.\n\nPrerequisites\n-----\n\nCode has been tested on the\n[2016.11.1](https://github.com/parallella/parabuntu/releases) and\n[2015.1](http://ftp.parallella.org/ubuntu/dists/trusty/image/) Parallella\nimages, but please use the former.\n\nYou must download and install the [COPRTHR-2\nSDK](http://www.browndeertechnology.com/coprthr2.htm) to be able to run the\n[./test](./test) and most [./example](./example) codes. The library is free for\nnon-commercial use.\n\nAlthough it's not required to build the library, a\n[Makefile](./src/Makefile.esdk) is provided if you're using the vendor-provided\neSDK.\n\nUsing\n-----\n\nYou may type `make` to build all directories, or `make [src|example|test]`\nto build individual subdirectories. Running `make run` will run example codes\nand a selection of test codes. Running `make check` will run all of the test\ncodes with various parameters. There is no installation, but you should link to\nthe _libshmem.a_ library and use the appropriate include path for _shmem.h_.\n\nIf you're not using the COPRTHR-2 SDK, you can build the library for the eSDK:\n`cd ./src; make -f Makefile.esdk`\n\nCitation\n-----\n\nIf you are using this work in an academic publication, please include the\nfollowing reference in your paper:\n\n*J.
