Nowadays, increasing importance has been attached to power management in modern data centers. A lot of solutions have been produced to reduce power consumption without producing an effect on quality of service. One common way is to associate with virtualization technology that has been widely used in data centers. This is due to not only its features of reliability and ease of management,but also...
The reduction of energy consumption in large-scale datacenters is being accomplished through an extensive use of virtualization, which enables the consolidation of multiple workloads in a smaller number of machines. Nevertheless, virtualization also incurs some additional overheads (e.g. virtual machine creation and migration) that can influence what is the best consolidated configuration, and thus,...
In recent years there has been renewal of interest in the relation between Green IT and High Performance Computing. The growing use of supercomputers has caused marked energy burden, putting negative pressure on electricity cost of computing centers. Scientists could foresee that the power consumption of computing facilities will double, triple, or even more in the next decade. Each year more and...
Although most large-scale systems are designed with the network as a central component, the interconnection network's energy consumption has received little attention. However, several software and hardware approaches can increase the interconnection network's power efficiency by using the network more efficiently or using throttling bandwidths to reduce the power consumption of unneeded resources.
