A blocked linear algebra program calling the sequential Level-3 BLAS can now run on both shared and distributed memory environments (which support Linda) by simply replacing each call by a call to the corresponding parallel Linda Level-3 BLAS. The authors summarise some of the implementation and algorithmic issues related to the matrix multiplication subroutine. All the various matrix algorithms being block-structured, they are particularly interested in parallel computers with hierarchical memory systems. Experimental data for their implementations show substantial speedups on shared memory, disjoint memory and networked configurations of processors. The authors also present the use of their parallel subroutines in blocked dense LU decomposition and present some preliminary experimental data.<<ETX>>","PeriodicalId":254515,"journal":{"name":"Proceedings Scalable High Performance Computing Conference SHPCC-92.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116390614","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}

As the number of processors increases, the conventional techniques for monitoring the performance of parallel systems will produce large amounts of data in the form of event trace files. The authors propose one possible solution to this data size problem: performance metric predicates. These predicates permit the user to define performance parameters that control the output of event trace data during the application's execution time. The authors assert that the use of performance metric predicates provides a powerful and useful tool for the control of event trace data output from large, complex systems.<<ETX>>","PeriodicalId":254515,"journal":{"name":"Proceedings Scalable High Performance Computing Conference SHPCC-92.","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126667794","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}

For solving large and sparse instances of these problems on parallel architectures with distributed memory, the use of static data structures to represent the sparse matrix is preferred during the factorization. But the accurate detection of the rank of the constraint matrix is also very critical to the accuracy of the computed solution. The author examines the solution of the constrained problem using weighting approach. All computations can be carried out using a static data structure that is generated using the symbolic structure of the input matrices, making use of a recently proposed rank detection procedure. The author shows good speed-ups in solving large and sparse equality conditioned least squares problems on hypercubes of up to 128 processors.<<ETX>>","PeriodicalId":254515,"journal":{"name":"Proceedings Scalable High Performance Computing Conference SHPCC-92.","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523961","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}

This method is presented within the context of a FORTRAN compiler. An approximate simulator has been incorporated within a parallel-code/domain-decomposition loop within the compiler. The simulator estimates the performance of candidate instruction segments, and guides the selection of appropriate code transformations, heuristics, and data storage strategies. At present, many aspects of the target machine are parameterized, to permit investigations of a number of parallel-computer architectures. In this paper, the compiler is illustrated for a Navier-Stokes computer target node application.<<ETX>>","PeriodicalId":254515,"journal":{"name":"Proceedings Scalable High Performance Computing Conference SHPCC-92.","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122234433","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}
