Multi-Threaded OpenSHMEM: A Bad Idea?

Abstract

The purpose of this document is to stimulate discussions on support for multi-threaded execution in OpenSHMEM. Why is there a need for any thread support at all for an API that follows a shared global address space paradigm? In our ongoing work, we investigate opportunities and challenges introduced through multi-threading, namely implementation challenges and opportunities and required -- as well desirable -- extensions to the API.
