Multi-model parallel programming in psyche

M. L. Scott, T. J. LeBlanc, B. D. Marsh
1990 Proceedings of the second ACM SIGPLAN symposium on Principles & practice of parallel programming - PPOPP '90  
This paper describes multi-model parallel programming in the Psyche multiprocessor operating system.  ...  Multi-model parallel programming is the simultaneous use of several different models, both across programs and within a single program.  ...  Finally we summarize the specific features of Psyche that facilitate multi-model programming.  ...

The Rochester checkers player: multimodel parallel programming for animate vision

B. Marsh, C. Brown, T. LeBlanc, M. Scott, T. Becker, C. Quiroz, P. Das, J. Karlsson
1992 Computer  
In this paper we describe Checkers, a multi-model parallel program that implements a robot checkers player.  ...  These multi-model programs require an underlying software system that not only suppons several different models of parallel computation simultaneously, but that also allows tasks implemented in different  ...  Brian Marsh is supported by a DARPAI NASA Graduate Research Assistantship in Parallel Processing.

First-class user-level threads

Brian D. Marsh, Michael L. Scott, Thomas J. LeBlanc, Evangelos P. Markatos
1991 Proceedings of the thirteenth ACM symposium on Operating systems principles - SOSP '91  
We have incorporated these mechanisms in the Psyche parallel operating system, and have used them to implement several different kinds of user-level threads.  ...  It is often desirable, for reasons of clarity, portability, and efficiency, to write parallel programs in which the number of processes is independent of the number of available processors.  ...  Acknowledgments We would like to thank Tom Anderson, Brian Bershad, David Black, Jan Edler, Carla Ellis, Ed Lazowska, and Hank Levy for their help in improving this paper.  ...

Large-scale parallel programming: experience with BBN butterfly parallel processor

Thomas J. LeBlanc, Michael L. Scott, Christopher M. Brown
1988 Proceedings of the ACM/SIGPLAN conference on Parallel programming: experience with applications, languages and systems - PPEALS '88  
The availability of multiple programming models is also a concern; truly general-purpose parallel computing will require the development of environments that allow programs written under different models  ...  It also demonstrates that the problems inherent in programming such machines are far from adequately solved.  ...  Implementing the file Figure 4 : Overlapping Protection Domains in Psyche system as a parallel program can significantly improve performance.  ...
