[0044] In case nine, when four computing power nodes are required to provide computing power, the above-mentioned execution entity can control the four computing power nodes to jointly provide computing power.

[0045] When the number of users operating is greater than or equal to the third preset number and does not exceed the fourth preset number.

[0051] In some embodiments, the execution entity may record user operations and store them in a predetermined database for query. This means that the execution entity records user operations in real time and temporarily stores the recorded results in the storage disk corresponding to the computing node that provides computing power to the user. When the user completes the operation and ends the service, the user's operation record is stored in the predetermined user operation record database for later query. In addition, the execution entity may store the user's business processing data in the storage disk of the computing node that provides computing power to the user for user access.

[0052] Compared with the prior art, the beneficial effects of the embodiments of the present disclosure are as follows: First, when the multi-node computing power server is running, the server motherboard monitors in real time the number of users who initiate operation requests through the client, so as to confirm which computing power node to call to provide computing power and whether a computing power pool needs to be formed. Then, when an operation request is received, the computing power node starts and provides computing power in response to the user operation. When the multi-node computing power server is running, it can be based on the pre-set first preset number, second preset number, third preset number, and fourth preset number, and then based on the number of users who initiate operation requests, the number of users currently operating, and the sum of the two to determine whether the computing power provided by the currently connected computing power node can meet the demand. If not, it is determined based on the above data how many more computing power nodes need to be connected or whether to prompt the administrator of insufficient computing power. Finally, the user operations are recorded and retained in a predetermined database for query, providing a way for later users to call historical operations.
