This book constitutes the proceedings of the 4th OpenSHMEM Workshop held in Annapolis MD USA
in August 2017.The 11 full papers presented in this book were carefully reviewed and selected
from 14 submissions. The papers discuss a variety of ideas for extending the OpenSHMEM
specification and making it efficient for current and next generation systems. This includes
new research for communication contexts in OpenSHMEM different optimizations for OpenSHMEM on
shared memory machines exploring the implementation of OpenSHMEM and its memory model on
Intel's KNL architecture and implementing new applications and benchmarks with OpenSHMEM.
