On the other hand, real-time Grid applications are emerging in many disciplines of science and engineering. Thus, it is natural to ask about the real-time performance of these file replication and replacement algorithms. Based on this motivation, in this study, the performance of three replication algorithms, namely fast spread, cascading, and caching, are evaluated together with three different file replacement policies, including least recently used, least frequently used, and least urgent first, under various Grid settings. For this evaluation, a process oriented and discrete-event driven simulator is developed. A detailed set of simulation studies are conducted using the simulator and the results obtained are presented to elaborate on the real-time performance of the aforementioned replication algorithms.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"362 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115897238","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}

Corbett","doi":"10.4108/GRIDNETS.2007.2070","DOIUrl":"https://doi.org/10.4108/GRIDNETS.2007.2070","url":null,"abstract":"In this paper we propose a technique for detecting under utilized resources (less than 70% memory utilization) due to memory bound processes by passively monitoring network traffic produced by the resource. To our knowledge, this is the first approach of its kind. One application of this technique is dynamic resource discovery (detection of resources with under utilized memory) in a High Performance Desktop or Cluster Grid computing environment confined to a low latency Local Area Network (LAN). Our method removes the need to communicate directly with resources to determine if their memory is under utilized, thus reducing traffic on the network. This is very important in a High Performance computing environment since data or computational intensive applications may be present. The proposed method creates a delay sensitive profile generated by the analysis of monitored network traffic due to High Performance UDP based services such as file transfer applications (FOBS, Tsunami, UDT, SABUL, etc.), message passing platforms (MPICH-G2/Score, etc.), and many more. An energy value is derived from the delay sensitive profile, which represents the state (over utilized memory or under utilized memory) of the resource of interest. Then a simple threshold is applied to the energy value to identify the state of the resource. Several scenarios have been investigated to determine the feasibility of the proposed technique. Results suggest that the proposed technique can use network traffic to extract delays associated with a resources' memory utilization and accurately determine the state of the resource.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"335 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123399051","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}

Using real workload data from production Grids, we show that the second order properties such as the autocorrelation function (ACF) and the scaling behavior can be well reconstructed by a Multifractal Wavelet Model (MWM). A so-called controlled-variability integrate-and-fire (CV-InF) algorithm is applied to transform rates into interarrivals so that a full description of the arrival process can be obtained. The additive nature of rates makes it possible to model different patterns separately and aggregate them back to form a unified process. We further quantify the performance impacts of autocorrelated job arrivals in Grid scheduling using model-driven simulation. It is shown that autocorrelations in the arrival processes can cause performance degradation both at the local and the Grid level.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128183439","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}

Sector was designed and developed to eliminate these barriers. The Sector architecture incorporates specialized communications services and specialized data services that are designed for high volume data flows over wide area high performance optical networks. This design employs several innovative techniques to ensure that data flows are maximized at all times and at all locations required regardless of distances.

New approaches like flow scheduling are proposed and studied as alternatives to traditional QoS and reservation proposals. To enable such flow scheduling approaches, runtime mechanisms controlling flow sending time and rate have to be implemented in the data plane. This paper quantifies and compares such end-host based mechanisms combined with transport protocols to instantiate different scheduling strategies in a range of latency conditions. We show that, a single-rate scheduling strategy implemented by an AIMD-based protocol and a packet pacing mechanism offers predictable performance and is insensitive to latency. This paper also highlights the limits of other strategies and rate limitation mechanisms like token bucket which generates unpredictability and other drawbacks.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128584417","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}
