The Cowichan Experience
نویسندگان
چکیده
The Cowichan problems are a suite for assessing the usability of parallel programming systems. By implementing these applications in Orca, many useful lessons were learned about the design and implementation of this parallel language.

متن کاملAsserting the utility of CO2P3S using the Cowichan Problem Set
Parallel programming environments provide a way for programmers to reap the benefits of parallelism, while reducing the effort required to create parallel applications. The CO2P3S parallel programming system is one such tool that uses a pattern-based approach to express concurrency. Using the Cowichan Problems, we demonstrate that CO2P3S contains a rich set of parallel patterns for implementing...
متن کاملWhy Not Use a Pattern-Based Parallel Programming System?
Parallel programming is seen as an effective technique to improve the performance of computationally-intensive programs. This is done at the cost of increasing the complexity of the program, since new issues must be addressed for a concurrent application. Parallel programming environments provide a way for users to reap the benefits of concurrent programming while reducing the effort required t...
متن کاملAssessing and Comparing the Usability of Parallel Programming Systems
Parallel programming is widely acknowledged to be more diicult than sequential programming. One reason for this is that parallel programming systems are more diicult to use than their sequential counterparts. In particular, few parallel programming systems can support the software engineering requirements of large applications. We intend to assess and compare the usability of a variety of paral...
متن کاملAssessing the Usability of Parallel Programming Systems: the Cowichan Problems
The only control-parallel programming model to win wide acceptance to date has been procedural message passing. One reason that higher-level systems have not been widely accepted is that there is no consensus on what they should ooer; one reason for this is that there has been no systematic comparison of the usability of alternatives models and systems. This paper describes a problem suite with...
