We demonstrate this benefit with an experiment in which we studied the protein folding process with the CHARMM molecular simulation package over a grid managed by Legion, a grid operating system. High-performance applications can take advantage of grid resources if the grid operating system provides both low level functionality as well as high-level services. We describe the nature of services provided by Legion for high-performance applications. Our experiences indicate that human factors continue to play a crucial role in the configuration of grid resources, underlying resources can be problematic, grid services must tolerate underlying problems or inform the user, and high-level services must continue to evolve to meet user requirements. Our experiment not only helped a scientist perform an important study, but also showed the viability of an integrated approach such as Legion's for managing a grid.","PeriodicalId":304683,"journal":{"name":"Proceedings 10th IEEE International Symposium on High Performance Distributed Computing","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122691390","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}

Beal","doi":"10.1109/HPDC.2001.945203","DOIUrl":"https://doi.org/10.1109/HPDC.2001.945203","url":null,"abstract":"Retrograde analysis is an efficient exhaustive search method. It is a powerful tool that can be used in solving problems where end states have known values but starting states do not. It has been widely used to solve mathematically-precise games such as chess endgames, and is potentially usable in energy-minimization problems. With increasing computing power, both in speed and storage capacity, retrograde analysis will become more and more useful. This paper looks at successful applications to games, the challenges ahead and the modifications that are required to utilize distributed hardware. The power and the usefulness of retrograde analysis are still limited by the computing resources one has access to. Today, the best sequential retrograde algorithms are capable of solving problems with about 10/sup 9/ states in a few hours on a standard personal computer. Bigger problems need more powerful computers, or take much longer to solve, or are simply out of the reach of today's technologies. Introducing parallelism to retrograde analysis is a natural way to attack the bigger problems. There are today three main architectures available for doing parallel retrograde analysis, namely symmetric multiprocessor (SMP) systems, high-speed network-based distributed systems and Internet-based distributed systems. In this paper, we discuss some of the key issues in doing parallel retrograde analysis on these different architectures. Technical challenges are addressed in detail, as well as some examples and proposals. These examples and proposals are drawn from various board games, but the ideas can be applied to other problem domains.","PeriodicalId":304683,"journal":{"name":"Proceedings 10th IEEE International Symposium on High Performance Distributed Computing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129404073","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}

We introduce the notion of a collective port which is an extension of the Common Component Architecture (CCA) ports and allows collective components representing parallel applications to interact as one entity. We further describe a class of translation components, which translate between the distributed data format used by one parallel implementation to that used by another. A well known example of such components is the MxN component which translates between data distributed on M processors to data distributed on N processors. We describe its implementation in Parallel Application Work Space (PAWS), as well as the data structures PAWS uses to support it. We also present a mechanism allowing the framework to invoke this component on the programmer's behalf whenever such translation is necessary, freeing the programmer from treating collective component interactions as a special case. In doing that, we introduce framework-based, user-defined distributed type casts. Finally, we discuss our initial experiments in building optimized complex translation components out of atomic functionalities.","PeriodicalId":304683,"journal":{"name":"Proceedings 10th IEEE International Symposium on High Performance Distributed Computing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125928564","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 three major aspects of modeling capabilities focused in NPSS, including integration of different engine components, coupling of multiple disciplines, and engine component zooming at appropriate level of fidelity, require relatively tight coupling of different analysis codes. Most of these codes in aerodynamics and solid mechanics are written in Fortran. Refitting these legacy Fortran codes with distributed objects can increase the code reusability. We describe our experiences in building a CORBA-based development environment for programmers to easily wrap and couple legacy Fortran codes. This environment consists of a C++ wrapper library to hide the details of CORBA and an efficient remote variable scheme to facilitate data exchange between the client and the server. We also report empirical performance evaluation results and describe current applications.","PeriodicalId":304683,"journal":{"name":"Proceedings 10th IEEE International Symposium on High Performance Distributed Computing","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959118","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}

To address this issue, we have proposed a flexible mechanism, called active frames, that provides a basis for selecting a set of available distributed computing resources, and then mapping tasks onto those resources. As a proof of concept, we have used active frames to build a remote visualization service, called Dv, that allows users to visualize the contents of scientific datasets stored at remote locations. We evaluate the performance of active frames, in the context of Dv. In particular, we address the following two questions: (1) what performance penalty do we pay for the flexibility of the active frames mechanism? (2) can the throughput of a service based on active frames be predicted with reasonable accuracy from micro-benchmarks? The results of the evaluation suggest that the overhead imposed by active frames is reasonable (roughly 5%), and that simple models based on micro-benchmarks can conservatively predict measured throughput with reasonable accuracy (at most 20%).","PeriodicalId":304683,"journal":{"name":"Proceedings 10th IEEE International Symposium on High Performance Distributed Computing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121375962","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}
