Parallel skeletons for structured composition
1995
Proceedings of the fifth ACM SIGPLAN symposium on Principles and practice of parallel programming - PPOPP '95
Preserved Fulltext
In this paper, we propose a straightforward solution to the problems of compositional parallel programming by using skeletons as the uniform mechanism for structured composition. ...
The ability to compose skeletons provides us with the essential tools for building further and more complex application-oriented skeletons specifying important aspects of parallel computation. ...
Special thanks are due to Moustafa Ghanem for his helpful comments on earlier drafts. ...
