In this paper, we present an early evaluation of the thread safety specification in the Unified Common Com- munication Substrate (UCCS) employed in OpenSHMEM. Results demonstrate that thread safety can be provided at an acceptable cost and can improve efficiency for some op- erations, compared to serializing communication.}, author = {Aurelien Bouteiller and Thomas Herault and George Bosilca} }
