The OpenSHMEM Workshop is an annual event dedicated to the promotion and advancement of the OpenSHMEM programming interface and to help shape its future direction. It is the premier venue to discuss and present the latest developments, implementation technologies, tools, trends, recent research ideas and results related to OpenSHMEM. This year's workshop will explore the ongoing evolution of OpenSHMEM to interoperate with other programming models and heterogeneous architectures. The focus will be on future extensions to improve OpenSHMEM on current and upcoming architectures keeping in mind the trend towards heterogeneity. Although this is an OpenSHMEM specific workshop, we welcome ideas used for other PGAS languages/APIs that may be applicable to OpenSHMEM.
