Treating a user-defined parallel library as a domain-specific language

D.J. Quinlan, B. Miller, B. Philip, M. Schordan
2002 Proceedings 16th International Parallel and Distributed Processing Symposium  
Our research work shows how to effectively treat any object-oriented library and its abstractions as if it where a domain-specific language with equivalent builtin types and specialized compile-time analysis  ...  In each case the semantics of the abstraction is user-defined and ignored by the compilation process at a significant performance penalty for the application code.  ...  The result is a mechanism which can take a C++ object-oriented library and produce the compile-time optimizations previously available only within a compiler for a domain specific language with similar  ...

Annotating user-defined abstractions for optimization

D. Quinlan, M. Schordan, R. Vuduc, Qing Yi
