Problems solved by technology

[0006] In practice, algorithms for scheduling tasks in clusters of high-performance computers are difficult to implement, because scheduling decisions must be made quickly according to multiple constraints and should be able to control potentially large computing resources
[0007] Then, it becomes more difficult to account for changes in electricity prices, because it needs to add some more constraints to the already complex scheduling algorithm

Embodiment Construction

[0057] figure 1 An example of the system is shown, showing the processes used by the management method according to an embodiment of the present invention and the processes of their interactions.

[0058] The management method according to the embodiment of the present invention uses two databases 1 and 2, database 1 for the prediction process 3 of electricity price and database 2 for the prediction process 4 of workload. Database 1 may include sensor data and historical data. Database 2 may only include historical data. The task scheduling process 7 utilizes the power price prediction made through the power price prediction process 3 and the workload prediction made through the workload prediction process 4, and the actual workload obtained through the actual workload sensing 5, and the actual power price sensing 6 One or more electricity prices derived from one or more different power sources respectively.

[0059] The task scheduling process 7 provides feedback to the el...

Abstract

This invention relates to a method of managing electricity providing in a computers cluster (8), comprising: a process of prediction of electricity price (3) provided by at least one electricity source, a process of prediction of workload (4) in said computers cluster (8), a process of scheduling tasks (7) in said computers cluster (8), based on both said prediction processes (3, 4).

Description

technical field [0001] The present invention relates to a method of managing power supply in a computer cluster, and a method of operating a computer cluster including a method of managing power supply in a computer cluster and a method of scheduling tasks in the computer cluster. Background technique [0002] According to the prior art, when managing a computer cluster, since the cluster includes many computers, sometimes at least hundreds of computers, or even at least thousands of computers, it is quite difficult to schedule a large number of tasks to be executed in the cluster. [0003] In practice, there are many parameters to consider, such as the number of tasks to be performed, the computing resources required by these tasks, the time deadlines associated with these tasks, and, where appropriate, the variation of all these parameters over time such that in a computer cluster It is quite difficult to schedule tasks in . [0004] A computer cluster requires at least o...
