Such a collection can be operated by proper software so as to provide the abstraction of a single, larger block device, made available to all the participants on a peer-to-peer basis. By adding enough data redundancy, the disk collection as a whole could act as single distributed RAID, providing capacity and reliability along with the convenient price/performance typical of commodity hard disks. This paper reports about issues of communication performance in a prototype of distributed RAID device called DRAID. DRAID offers storage services under a single I/O space (SIOS) block device abstraction. The SIOS feature implies that the storage space is accessible through each of the participant stations, rather than through one or few fixed end-points. The paper focuses on the inefficiency of communication when a client reads data stripes from a number of remote servers in a gigabit Ethernet LAN. The congestion caused by such many-to-one communication pattern has been faced in multiple ways, but the best result has been obtained by modifying the traditional, and unsuccessful, congestion avoidance policy of TCP/IP.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131850090","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}

Key characteristics of a global-scale grid are the strong burstiness in the amount of load on the resources and on the network capacities, and the fact that processors may be appended to or removed from the grid at any time. To cope with these characteristics, it is essential to develop techniques that make applications robust against the dynamics of the grid environment. For these techniques to be effective, it is important to have an understanding of the statistical properties of the dynamics of a grid environment. Today, however, the statistical properties of the dynamic behavior of real global-scale grid environments are not well understood. Our main focus is on highly CPU-intensive grid applications that require huge amounts of processor power for running tasks. Motivated by this, we have performed extensive measurements in a real, global-scale grid environment to study the statistical properties of the running times of tasks on processors. We observe (1) a strong burstiness of the running times over different time scales, (2) a strong heterogeneity of the running-time characteristics among the different hosts, (3) a strong heterogeneity of the running-time characteristics for the same host over different time intervals, and (4) the occurrence of sudden level-switches in the running times, amongst others. These observations are used to develop effective techniques for the prediction of running times. They can be used to develop effective control schemes for robust grid applications.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124277737","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 Lambda-Grid offers dedicated, optical, circuit-switched, point-to-point connections, which may be reserved exclusively for an application. Though such dedicated high-speed connections eliminate congestion in the network, they effectively push the network congestion out to the end systems, as processing speeds have not kept up with networking speeds. Therefore, developing an efficient transport protocol over such highspeed dedicated circuits is of critical importance. In this work, we propose the idea of a lightweight end-system protocol, based on performance monitoring, to significantly improve the performance of data transport over a LambdaGrid. In particular, we focus on dynamically monitoring the OS task scheduling at the receiving end-system so that potential end-system congestion may be detected early and appropriate feedback can be transmitted back to the sending end-system to avoid packet losses. One example of such an evasive action is to suspend transmission for certain duration of time during which the OS on the receiving end-system must handle other computational processes. With this in mind, we propose to extend the Reliable-Blast UDP (RBUDP) protocol to take such evasive action by using a simple feedback mechanism that is activated via performance monitoring. The new protocol, named RBUDP dramatically improves the performance of data transfer over LambdaGrids. We demonstrate the effectiveness of our proposed protocol and illustrate the performance gains achieved via network emulation.","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121961438","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 new paradigm involves coordinating and sharing computing, application, data, storage, and network resources across dynamic and possibly geographically dispersed organizations. To attract organizations to take advantage of off-the-shelf ready-to-build commodity clusters, substantial improvements have been realized in many areas such as resource allocation and management, process distribution and recovery, data integrity and application security. However, the primary factor above all others as we approach this new level of computing is trust - higher confidence in the privacy and security of data and resources is needed to advance to the next level. Most organizations avoid running applications using their private data on systems that are not under their control until a sufficient confidence of trust is built. Proofs of information security help build a higher level of trust and thus increase the utilization of the shared cluster. When launch applications on computer systems, five potential security threats arise at user, protocol, system, communication and hardware levels. To secure information, each level has to execute a set of protection tasks. Full trust will be achieved after all levels are proven immune from attack. In a conventional system, security is guaranteed if the hosting system is wholly controlled by the applications. Therefore, to protect confidential data between applications in a shared system, the traditional approach is to separate the entire system by either spatial or time methods. Here we introduce a resource separating and grouping mechanism that physically and logically separates system resources by adaptable scale to eliminate security problems and reduce the overall cost","PeriodicalId":419226,"journal":{"name":"Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127170697","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}
