In order to realize green ecosocieties, the total electric power consumption of computers and networks is required to be reduced. In applications on distributed systems, clients issue service requests to servers and then servers send replies to clients. Here, we discuss how much electric power a server consumes since the power consumption of a client is neglectable compared with a server. We classify...
In energy-aware information systems, it is critical to discuss how to select a server for each request from clients in order to not only achieve performance objectives but also reduce the total power consumption of a system. In order to design and evaluate the server selection algorithm, it is critical to define the power consumption model of a server to perform processes. In our previous studies,...
In information systems, a client first selects a server in a cluster of servers and issues a request to the server. The request is performed as a process in the server. In this paper, we consider a communication process which mainly consumes communication resource. It is critical to discuss how to select a server for each request from clients in order to not only achieve performance objectives but...
The electric power consumption of information systems has to be reduced in addition to increasing the performance and fault-tolerancy in order to realize green societies. In information systems, servers mainly consume the electric power to perform processes requested by clients. We consider computation (CP) and storage (ST) types of application processes on servers. In CP and ST processes, CPU and...

The power consumption of information systems, especially servers has to be reduced to realize green eco-society. A client first selects a server in a collection of possible servers and issues a request to the server. The request is performed as a process in the server. In this paper, we consider a computation type of application where CPU resource is mainly used in a server. It is critical to discuss...
The electric power consumption of servers has to be reduced in information systems in order to realize green societies. In information systems, servers mainly consume the electric power to process regrets from clients. We have to reduce the electric power consumed by servers. There are computation (CP), communication (CM), and storage (ST) types of applications to be performed on servers. In CP and...
The electric power consumption of servers hasto be reduced in information systems in order to realize green societies. In information systems, clients issue requests to servers and the servers spend electric power to handle the requests. We have to reduce the power consumption of servers since servers mainly consume electric power compared with clients. There are computation (CP), communication (CM),...
The extended power consumption laxity-based (EPCLB) algorithm is discussed for reducing the total power consumption of servers in general type applications in this paper. However, each time a load balancer receives a new request, the load balancer has to collect the state on computation and transmission laxities of processes and traffic in each server and estimate the power consumption to perform...
In order to realize digital ecosystems, the total electric power consumption of servers to perform application processes has to be reduced in information systems. Applications are classified into three types, computation, communication, and storage types of applications. In the computation and communication types of applications, CPU and communication resources of computers are mainly consumed, respectively...
In information systems, it is critical to reduce the total electrical power consumption of computers and networks in order to realize digital ecosystems. In the extended power consumption laxity-based (EPCLB) algorithm, a server is selected in a set of possible servers so as to not only satisfy deadline constraint but also reduce the total power consumption of servers in general types of applications...
