| الوصف: | Recently, cloud computing has widely used with the advance of network and virtualization technologies. As cloud computing becomes popular, the number of servers in data center becomes large, and the electric power consumption of these servers also becomes a large problem. Linux gives us some functions to reduce electric power consumption, but their operations are difficult for beginners of server administration because they have to be modified some distributed files by hand. For easy operations of power saving functions, we develop a tool “LPST” that makes full use of power saving functions of linux. LPST equips GUI to handles the power saving functions of the following four devices, CPU, HDD, display and USB device through ACPI and cpufreq kernel module. To adapt many kinds of linux distributions, we implement LPST in java. The electric current of a server was reduced from 1.24A to 1.06A through the change of CPU governor from “performance” to “powersave” by developed LPST. |
