Such hardware is frequently abundant at research locations, so PVM incurs little or no hardware costs. PVM is also flexible: it uses existing communication networks (Ethernet or fiber) and remote procedural libraries; it lets programmers use either C or Fortran; and it can emulate several commercial architectures including hypercubes, meshes, and rings. The authors believe that PVM can compete effectively with traditional supercomputers, and they have demonstrated its computational power and cost-effectiveness by simulating the propagation of seismic waves using an isolated Ethernet ring comprising an IBM RS/6000 550 as the host and six RS/6000 320H machines as the nodes.<<ETX>>","PeriodicalId":325213,"journal":{"name":"IEEE Parallel & Distributed Technology: Systems & Applications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128471397","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 Virtual Network, an idealized, intelligent software network that hides the underlying physical network's incompatibilities and complexities from the distributed programs that run on it, is presented as a solution. The components of the Virtual Network are described, and meta communication, error handling, system administration, performance, and security issues are discussed. The Virtual Network is compared with DCE RPC, the de facto standard. The use of the Virtual Network framework to quickly design and implement a useful, sophisticated distributed application, the distributed Ada compilation tool, is described.<<ETX>>","PeriodicalId":325213,"journal":{"name":"IEEE Parallel & Distributed Technology: Systems & Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130174245","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 long as one processor is working, the computation can continue. The authors use the underlying principle of inherent fault tolerance, turning redundancy into computation power, to design a model of repetitive fault tolerance that is suitable for dataflow computations. When no processors fail, they all work in parallel to achieve performance almost equal to that of the parallel program without fault tolerance. If processors do fail, the program can still derive the correct result as long as at least one processor is working; failures only slow the computation speed. Repetitive fault tolerance also provides a systematic way to derive fault-tolerant programs.<<ETX>>","PeriodicalId":325213,"journal":{"name":"IEEE Parallel & Distributed Technology: Systems & Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126130244","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}

Developers using Enterprise do not deal with low-level programming details such as marshalling data, sending/receiving messages, and synchronization. Instead, they write their programs in C, augmented by new semantics that allow procedure calls to be executed in parallel. Enterprise automatically inserts the necessary code for communication and synchronization. However, Enterprise does not choose the type of parallelism to apply. The developer is often the best judge of how parallelism can be exploited in a particular application, so Enterprise lets the programmer draw a diagram of the parallelism using a familiar analogy that is inherently parallel: a business organization, or enterprise, which divides large tasks into smaller tasks and allocates assets to perform those tasks. These assets correspond to techniques used in most large-grained parallel programs; pipelines, master/slave processes, divide-and-conquer, and so on,and the number and kinds of assets used determine the amount of parallelism.<<ETX>>","PeriodicalId":325213,"journal":{"name":"IEEE Parallel & Distributed Technology: Systems & Applications","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121261922","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 performance of four applications of Mentat on two platforms-a 32-node Intel iPSC/2 hypercube and a network of 16 Sun IPC Sparcstations-are examined. The applications are DNA and protein sequence comparison, image convolution, Gaussian elimination and partial pivoting, and sparse matrix-vector multiplication. The performance of Mentat in these applications is compared to that of object-oriented parallel-processing systems, compiler-based distributed-memory systems, portable parallel-processing systems, and hand-coded implementations of the same applications.<<ETX>>","PeriodicalId":325213,"journal":{"name":"IEEE Parallel & Distributed Technology: Systems & Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122443762","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}
