Abstract(s)
Modern organizations depend on
computers to work. Text processing, CAD,
CAM, simulation, statistical analysis and so on
are fundamental for maintaining high degree of
productivity and competitiveness. Computers in an
organization, consume a considerable percentage of
the overall energy and, although a typical computer
provides power saving technologies, such as
suspending or hibernating components, this feature
can be disabled. Moreover, the user can opt for
never turning off the workstation. Well defined
power saving policies, with appropriate automatic
mechanisms to apply them, can provide significant
power savings with consequent reduction of the
power expense. With several computers in an
organization, it is necessary to build the profile of
the energy consumption. We propose installing
a software probe in each computer to instrument
the power consumption, either directly, by using
a power meter, or md1rectly, by measuring the
processor performance counters. This distributed
architecture, with software probes in every computer
and a centralized server for persistence and decision
making tries to save energy, by defining and applying
organization level power saving policies.
