The Extended Power Consumption Model to Perform Computation Type Application Processes on Virtual Machines

Scalable and high performance server cluster systems like cloud computing systems are equipped with virtual machines to efficiently utilize server resources. On the other hand, a large amount of electric energy is consumed in a server cluster system since multiple servers consume electric energy to perform application processes on virtual machines. In order to design and implement an energy-aware server cluster system, the computation model of a virtual machine and power consumption model of a server have to be defined. In our previous studies, we proposed the power consumption model of a server and computation model of a virtual machine to perform application processes on virtual machines. However, the proposed power consumption model and computation model does not consider the change of the clock frequency of each core in a server. In this paper, we consider the change of the clock frequency of each core in a server. Then, we newly proposed the extended power consumption model of a server and computation model of a virtual machine to perform computation type application processes.
