2017 IEEE Transactions on Parallel and Distributed Systems  
Support for expression of data locality has been explored in the past, but those efforts have had only modest success in being adopted in HPC applications for various reasons.  ...  Data locality abstractions are available in the forms of libraries, data structures, languages and runtime systems; a common theme is increasing productivity without sacrificing performance.  ...  An emerging trend in HPC is to delegate responsibilities to libraries, compilers, and runtime systems.  ...
