Abstract: A water environment temperature measurement tool includes measurement boxes and a counterweight box; a plurality of groups of the measurement boxes are provided; the counterweight box is movably connected with a group of measurement boxes; and each measurement box is provided with a temperature measurement instrument inside. The water environment temperature measurement tool further comprises: control mechanisms, each comprising a water inlet pipe, a water retaining member, an elastic member, a control assembly, a rotating seat, a rotating shaft, a second screw rod, a control seat and a rotary assembly. In the water environment temperature measurement tool of the present invention, the control mechanisms can achieve extraction and temperature measurement of water at different water body depths by cooperating with the measurement boxes and the temperature measurement instruments.

Abstract: Embodiments of the invention relate generally to the field of power management of computer systems, and more particularly to a method and apparatus for dynamically allocating power to servers in a server rack. The method comprises: measuring power consumption of a computer system having one or more servers; estimating probability distribution of power demand for each of the one or more servers, the estimation based on the measured power consumption; estimating performance loss via the estimated probability distribution; computing power capping limits for each of the one or more servers, the computation based on the estimated probability distribution and the performance loss; and dynamically allocating the power capping limits to each of the one or more servers by modifying previous power capping limits of each of the one or more servers.
