High-reliability control method for low-energy-consumption computer cluster nodes

Abstract

The invention discloses a high-reliability control method for low-energy-consumption computer cluster nodes. The method comprises the following steps: grouping the nodes in a cluster; limiting node startup times of the groups at a certain number when the nodes are waken up in order that the node startup times do not exceed a certain threshold; and limiting shutdown times of the node groups during energy-saving scheduling in order that the shutdown times do not exceed a certain threshold. Compared with a conventional unlimited scheduling algorithm, the high-reliability control method has the advantages that total startup and shutdown times of a system can be reduced effectively. Meanwhile, the startup and shutdown times are distributed to the node groups as uniform as possible, so that early failure of a part of nodes due to centralization of the startup and shutdown times on certain nodes is avoided, thereby lowering the energy consumption of a cluster system, and enhancing the reliability of the system at a certain degree. Moreover, the startup and shutdown times of the nodes in the groups can be borrowed, so that certain flexibility is realized, and the energy consumption of the system can be lowered to the maximum extent.

Description

Technical field [0001] The present invention relates to a high-reliability control method for low-energy-consumption computer cluster nodes. The field of the claimed technical scheme of the present invention is the field of computer cluster systems. Background technique [0002] In the past, people generally regarded power consumption and energy consumption as key considerations for embedded devices such as handheld devices and mobile devices. Because these devices are usually powered by batteries and are not connected to the public grid. In addition, energy consumption also determines the use time of these devices. For example, mobile devices, etc., so there are many low-power and low-power designs for these devices. However, in many large-scale computer cluster systems nowadays, energy consumption has become an increasingly important cost. The management of power and energy is also crucial for server clusters. The energy saving of large-scale cluster systems has become an iss...

AI Technical Summary

Problems solved by technology

The current energy-saving scheduling methods for cluster systems do not consider the impact of startup or shutdown on node reliability, but only from the perspective of energy conservation, and do not reduce costs from the perspective of node reliability.

[0005] Therefore, in view of the problems encountered in the above scenarios, an improved method is urgently needed to solve the reliability problem of nodes under energy-saving scheduling of the cluster system.
