In this paper we show the Cloner user interface, discuss how guided access is accomplished, and provide an example of how Cloner supports the rapid development of high performance codes. The example demonstrates how menu options and queries are used to guide a user to select an appropriate 2-dimensional FFT algorithm based on image site and available machine resources.<<ETX>>","PeriodicalId":146277,"journal":{"name":"Proceedings of Scalable Parallel Libraries Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132522070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increased complexity of the memory systems and the increased range of problem sizes for which a given piece of software is used poses serious challenges for software developers. The Connection Machine Scientific Software Library, CMSSL, uses several novel techniques to meet these challenges. The CMSSL contains routines for managing the data distribution and provides data distribution independent functionality. High performance is achieved through careful scheduling of operations and data motion, and through the automatic selection of algorithms at run-time. We discuss some of the techniques used, and provide evidence that CMSSL has reached the goals of performance and scalability for an important set of applications.<<ETX>>","PeriodicalId":146277,"journal":{"name":"Proceedings of Scalable Parallel Libraries Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132815856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis involves solution of extremely large systems of differential and algebraic equations. Differential-Algebraic Equation (DAE) solvers have been used to solve problems similar in nature to the transient stability analysis (TSA) problem. This paper discusses the possibility of the use of the existing DAE solvers to solve the transient stability analyse's application. We also discuss our research in developing a scalable, parallel DAE solver for use by the power system community and in related applications.<<ETX>>","PeriodicalId":146277,"journal":{"name":"Proceedings of Scalable Parallel Libraries Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115273343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partitioning such applications can be posed as a graph-partitioning problem based on the computational graph. The partitioning problem is in the class of NP-complete problems; hence exact solutions are computationally intractable for large problems. However, good suboptimal solutions are sufficient for effective parallelization of a large class of these applications. We are currently developing a library of partitioners based on physical optimization and related methods. In this paper, we describe an outline of the different methods and current status of our library.<<ETX>>","PeriodicalId":146277,"journal":{"name":"Proceedings of Scalable Parallel Libraries Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126052632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explain the utility of these features and give examples of the calling sequences that implement them. All of these features are seen as enablers for parallel library development and large applications.<<ETX>>","PeriodicalId":146277,"journal":{"name":"Proceedings of Scalable Parallel Libraries Conference","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116638351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
