To overcome this problem, multipath ATM switches have been investigated. We propose a class of ATM switch architectures that are constructed based on 3/spl times/3 switch elements (SEs). The proposed structures are constructed by adding lateral links to the banyan network to provide many paths between each input/output pair. As a result, the cell losses caused by internal conflicts are significantly reduced. And the proposed switch models are very modular, easy to expand, and use self-routing. The proposed switches use output queues to deal with the problem of cell sequence. From the analysis and simulation results, the proposed switches have the features of low cell loss probability and low cell delay.","PeriodicalId":145111,"journal":{"name":"Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128563906","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}

Zhai, 1997; G.F. Ding, 2003). However, a problem, how to improve the simulating speed when visualization and dynamical computation are considered at the same time, is still not overcome. Here, based on existing success, we present a distributed COM technology, which is used to change the status of the present slow speed simulation. Here, at first, the locomotive-track dynamics system is modeled, a resolving formula is discussed, and visualization of the system is given, then the characteristic of the main integration resolving algorithm is analyzed, which is the reason of actuating the DCOM method. Secondly, we divide these resolving equations into several separated module, which is distributed in different resolving machine as a COM, and construct a distributed parallel computing environment, this method effectively reduces the computing load of the main computer and the computing speed is improved, which is the basement of real-time simulation such as virtual dynamical test of locomotive.","PeriodicalId":145111,"journal":{"name":"Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies","volume":"302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128579226","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}

In all cases, n/spl les/m. The first strategy is based on the heuristic paradigm of equipartitioning, and the second is based on the notion of marginal analysis. Equipartitioning uses no a priori information when processor allocations are made to parallel jobs. Marginal analysis, on the other hand, assumes full a priori information in order to maximize processor utility. We compare both strategies with respect to average time-to-completion (system performance) and overall time-to-completion (system efficiency). Using a simple job model characterized by sequential time-to-completion and degree of parallelism, it is demonstrated via simulation that in most cases, the uninformed strategy of equipartitioning outperforms marginal analysis with respect to system performance and without a commensurate degradation in system efficiency.","PeriodicalId":145111,"journal":{"name":"Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121326330","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 targeted programs are perfect innermost loops. By using the technique called if-conversion, the control dependence can be converted to data dependence to prediction variables. Then an innermost loop can be represented by a data dependence graph, where the vertex supports the expression statements of high level languages. By mapping the data dependence graph to fixed PEs, each PE steps the loop iteration automatically and independently at the runtime. The execution forms multiple pipelining chains. The simulation of four loops of LFK shows the effectiveness of the LEAP architecture, compared with traditional CISC and RISC architectures.","PeriodicalId":145111,"journal":{"name":"Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116441696","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}

In order to reduce system outages due to aging phenomenon, software rejuvenation, a proactive fault-tolerance strategy has been introduced into cluster systems. Compared with clusters of a flat architecture, in which all the nodes share the same functions, we model and analyze the dispatcher-worker based cluster systems, which employ prediction-based rejuvenation both on the dispatcher and the worker pool. To evaluate the effects of rejuvenation, stochastic reward net models are constructed and solved by SPNP (stochastic Petri net package). Numerical results show that prediction-based software rejuvenation can significantly increase system availability and reduce the expected job loss probability.","PeriodicalId":145111,"journal":{"name":"Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116448086","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}
