【正文】 . . . . .An Evaluation of KVM for Use in Cloud Computing,and Clemson UniversityIn this paper we describe a virtual cluster based on the Kernelbased Virtual Machine(KVM as an alternative to VMWare and cally we show how the virtual cluster is built and tailored to t virtual technique presented in this paper,known as the Virtual Organization Cluster Model,shows great potential for cloud our implementation, we used a minimalist installation of Slackware Linux12on14pute nodes,ensuring minimal host prototype Virtual Organization Cluster is posed of28virtual putes nodes,each running Condor,and of testing the prototype were encouraging,with the exception of network performance.Categories and Subject Descriptors: [Computer Systems Organization]:Performance of Systems Design studies。Performance attributes。[ComputerCommunication Networks]:Distributed SystemsGeneral Terms:Design,Experimentation,Measurement,PerformanceAdditional Key Words and Phrases:Virtual Machines,KVM,HighPerformance ComputingA current problem in scienti c puting is that the expertise needed to deploy and maintain a cluster remains scarce despite recent declines in hardware costs. Smaller research groups may not be able to a ord to have their own clusters,and purchasing time on an existing cluster raises concerns such as vendor lockin and data security.In this paper,we present a cloud puting model which de nes a minimum speci cation for a pute cluster39。s sole purpose is to host other pute clusters through this way,a Virtualization Service Provider (VSPcan sell pute power without having to directly maintain each enduser39。s particular application.Similarly,Virtual Organizations(VO39。scan purchase pute power from VSP39。s without having to worry about hardware or software VO is free to develop a model cluster locally,perhaps even on a personal workstation,test it,andAuthors39。address:School of Computing,Clemson University,Clemson,SC296340974,USA. {mfenn,mamurph,sebgoa}@This material is based upon work supported under a National Science Foundation Graduate Research Fellowship.Permission to make digital/hard copy of all or part of this material without fee for personal or classroom use provided that the copies are not made or distributed for pro t or mercial advantage,the ACM copyright/server notice,the title of the publication,and its date appear,and notice is given that copying is by permission of the ACM, copy otherwise,to republish, to post on servers,or to redistribute to lists requires prior speci c permission and/or a fee.c 20YY ACM15293785/20YY/07000001$ACM Transactions on Computational Logic,Month20YY,Pages1 0??.2 et al.
