The code uses an explicit time-advance procedure on a staggered three-dimensional Eulerian mesh. They have implemented a two-dimensional latitude/longitude domain decomposition message passing strategy. Both dynamic memory management and interprocess communication are handled with macro constructs that are preprocessed prior to compilation. The code can be moved about a variety of platforms, including massively parallel processors, workstation clusters, and vector processors, with a mere change of three parameters. Performance on the various platforms as well as issues associated with coupling different models for major components of the climate system are discussed.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122518004","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 fundamental advances incorporated in such an environment can provide efficient solutions to the problem of information management. To establish this environment, the authors tackle the fundamental problems of observability and controllability of broadband networks. A virtual world provides a next-generation network management interface through which a user can observe and interact with the network directly in real time. The system that the authors are developing uses a 3D virtual world as the user interface for managing a large gigabit ATM network. It provides the capability for experimentation in all aspects of network transport, control and management.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123181219","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}

Motivated in particular by multimedia applications, POC is an end-to-end connection that provides a partial order service, that is, a service that requires some, but not all objects to be received in the order transmitted. This paper discusses R-PO, a reliable version of POC which requires that all transmitted objects are eventually delivered. A metric based on the number of linear extensions of a partial order in the presence of no lost objects is proposed to quantify different partial orders. Means for its calculation is presented when P can be modeled as a combination of sequential and/or parallel compositions of Petri-nets. This metric allows one to compare and evaluate the complexity of different partial order services.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124394503","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 program attempts to compute tests to detect all faults in a given list. The fault list is equally divided among the processors. The entire process consists of a series of parallel computing passes with synchronization occurring between passes. During a pass, each processor independently generates test sequencies for the assigned faults through vector generation and fault simulation. A fixed per-fault CPU time limit is used within a pass. Faults requiring more time are abandoned for later passes. Each processor simulates the entire fault list with its vectors and communicates the list of undetected faults to all other processors. Processors then combine these fault lists to create a list of faults that were not detected by all processors. This list is again equally divided and the next pass begins with a larger per-fault time limit for test generation. The process stops after either the required fault coverage is achieved or the pass with given maximum per-fault time limit is completed. Some benchmark results are given to show the advantage of distributed system for large circuits. Finally, the authors study a speedup model that considers duplicated computation and interprocessor communication.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123555595","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}

Load balancing is achieved through the use of comb distribution to roughly assign the same amount of pixels to each processor first, and then dynamically redistribute excessive loads among processors to keep each processor busy. In this model, there is no need for a master node to be responsible for dynamic scheduling. When each node finishes its job, it just requests an extra job from one of its neighbors. The authors implement their algorithm on Intel Delta Touchstone machine with 2-D mesh network topology and provide simulation results. With their scheme, they can get good speedup and high efficiency without much communication overhead.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117343284","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 disparity has made the storage subsystem a major bottleneck for many applications. Disk arrays that can service multiple disk requests simultaneously are being used to satisfy increasing throughput requirements. Higher throughput rates can be achieved by increasing the number of disks in an array. This increases the number of actuators that are available to service separate requests. It also spreads the data among more disk drives, reducing the seek time as the number of cylinders utilized on each disk drive decreases. The result is an increase in throughput that exceeds the increase in the number of disks. This suggests a tradeoff between the space utilization of disks in an array and the throughput of the array.<<ETX>>","PeriodicalId":226280,"journal":{"name":"[1993] Proceedings The 2nd International Symposium on High Performance Distributed Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693487","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}
