Depending on the state of the cellular automaton, rather different responses may occur when a new task is assigned to a resource. It may change nothing or generate avalanches that reconfigure the state of the system. the proportion between the abundance of avalanches and their sizes shows a power-law relation, a scale-invariant behavior that does not need to be tuned. That means that large - catastrophic - avalanches are very rare but small ones occur very often. Such a smart and emergent behavior fits well with the idea of non-clairvoyant scheduling, where tasks are load balanced into computing resources trying to maximize the performance but without assuming any knowledge on the tasks features. In order to study the viability of the approach, we have conducted an empirical experimentation which shows that the sand pile is able to find near-optimal schedules by reacting differently to different conditions of workloads and architectures.","PeriodicalId":364233,"journal":{"name":"2012 Seventh International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125338735","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}

Traditionally, such pleasingly parallel workloads are parallelized using standard batch scheduling or, on a larger scale, web-service-based grid middleware, which is traditionally based on SOAP web services. It is argued that Restful web services provide a natural framework for such asynchronous distributed computing and allow an architecture more suited for on-demand computing. Concretely, the services of the Grid Factory distributed computing system are described. These services are implemented as Apache modules, leveraging Apache APIs for access control and database access. Moreover, the standard Apache modules mod_dav and mod_ssl are used for file serving, authentication and and encryption. The characteristics of the system are described and the performance of this direct use of Apache as hosting platform is evaluated. The system has been subjected to initial testing, demonstrating the feasibility of the approach.","PeriodicalId":364233,"journal":{"name":"2012 Seventh International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133182898","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}

Usually, DCSV channels are either user generated or dedicated channels and they suffer adversely from poor channel performance, mainly, due to having a small number of participants. As a result, when a viewer explicitly requests for a block of streaming content, the probability that the requested block of data will be available among the existing viewers is less than what is required in order to offer a continuous service. We propose HnH (short for Hand in Hand), a novel scheme of cross-channel resource sharing, in order to solve the performance problem of DCSV channels due to their small number of viewers. We next develop a discrete-time stochastic model in order to analyze the performance issues of the proposed HnH scheme and provide insight into it. Numerical experiments were conducted in order to first validate the stochastic model, and then to evaluate the performance of the HnH scheme. Experiments showed that the HnH scheme allows an improvement of the quality of service for the viewers of DCSV channels.","PeriodicalId":364233,"journal":{"name":"2012 Seventh International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114723966","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}
