The algorithm, known as the U-mesh algorithm, is shown to scale well in four ways: with the dimension of the mesh, with the number of destinations, with the system size, and with the problem size. It is demonstrated that the only factor that affects the multicast latency is the number of destinations and that, for a given number of destinations, the number of time steps required to perform a multicast operation is minimal. Performance measurements of implementations on a 64-node nCUBE-2 and a 168-node Symult 2010 are given.<<ETX>>","PeriodicalId":117789,"journal":{"name":"[Proceedings 1992] The Fourth Symposium on the Frontiers of Massively Parallel Computation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116148685","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 scheme uses heuristics to distribute the loop iterations unevenly among processors in order to mask the delay caused by data dependencies and inter-PE (processing element) communication. Simulation results have shown that this scheme is effective for loops that have a large degree of parallelism among iterations. The scheme, due to its nature, distributes loop iterations among PEs based on architectural characteristics of the underlying organization, i.e. processor speed and communication cost. The maximum speedup attained is very close to the maximum speedup possible for a particular loop even in the presence of inter-PE communication cost. This scheme utilizes processors more efficiently, since, relative to the equal distribution approach, it requires fewer processors to attain maximum speedup. Although this scheme produces an unbalanced distribution among processors, this can be remedied by considering other loops when making the distribution to produce a balanced load among processors.<<ETX>>","PeriodicalId":117789,"journal":{"name":"[Proceedings 1992] The Fourth Symposium on the Frontiers of Massively Parallel Computation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124503261","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 solution of the radiation field usually dominates the R-MHD computation. The authors solve the linear Boltzmann equation for the radiation field intensity, using the deterministic S/sub N/ discrete ordinates method. Choosing an energy-domain decomposition the authors have implemented the S/sub N/ method on a parallel processor, the Intel iPSC/860, and the speedups are very favorable. Increasing almost linearly with the number of processors, the speedup reaches 14 on 16 processors.
