Knowledge of the type, volume, and frequency of events that occur in common patterns of I/O activity can provide insight into the policies and mechanisms needed at all levels of the memory hierarchy. This paper is a detailed case study of one scientific application's dynamic I/O behavior. Results from this study show that with appropriate measurement tools, dynamic I/O behavior can be characterized and regular, recurring patterns of I/O activity can be isolated.<<ETX>>","PeriodicalId":288344,"journal":{"name":"Proceedings of International Workshop on Modeling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126741045","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}

A performance study of the RPE mechanism for PDES PDES RPE机制的性能研究

RPE is an optimistic time warp based mechanism, which allows logical processes on one processor to execute remotely on another when the former is lagging behind in the computation. The advantage is that processors running too far ahead need neither wait, nor run excessively optimistically: they can instead do some useful work for processors which are falling behind. The disadvantage of course, is the cost associated with running processes remotely. The experiments we have run so far show that performance can be significantly enhanced through RPE under the right conditions. In particular, as expected, the site of computation grains was found to be of primary importance. Though our tests were ran with relatively few processors, we suggest a few simple modifications which should allow the scheme to work well for large numbers of computing elements.<<ETX>>","PeriodicalId":288344,"journal":{"name":"Proceedings of International Workshop on Modeling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122110850","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}

Scalability analysis tools for SPMD message-passing parallel programs 用于SPMD消息传递并行程序的可伸缩性分析工具

Sarukkai","doi":"10.1109/MASCOT.1994.284425","DOIUrl":"https://doi.org/10.1109/MASCOT.1994.284425","url":null,"abstract":"Tools to study the scalability of parallel programs, as number of processors (p) executing the program and problem size (n) being solved are increased, are a critical component of performance debugging environments for parallel programs. Simulations and scalability metrics have been used to address this issue. Simulation can accurately predict the execution time of a program for a specific (n,p) pair. However, it suffers from the drawback that one needs to simulate the program for each (n,p) pair of interest. On the other hand, while scalability metrics express the program performance as functions of n and p, they have been targeted to specific applications and there are no tools to automatically obtain simple first order scalability trends for generic parallel programs. We address the issue of automatically obtaining scalability trends for a class of data-independent message passing SPMD parallel programs. We validate our approach by considering example parallel programs executed on the Intel iPSC/860 hypercube. We show that insight into the scalability of the program can be obtained, using this approach.<<ETX>>","PeriodicalId":288344,"journal":{"name":"Proceedings of International Workshop on Modeling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133223979","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 the other class of approaches, points on the effective bandwidth curve of the source are estimated by monitoring the occupancy of buffers; an estimate of the effective bandwidth curve of the source is then found by interpolation and extrapolation using these points.<<ETX>>","PeriodicalId":288344,"journal":{"name":"Proceedings of International Workshop on Modeling, Analysis and Simulation of Computer and Telecommunication Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549214","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}
