[0048] At present, when it is necessary to ensure the operation of the first activity in the first activity set, more processing unit resources are usually pre-allocated to ensure the operation of the first activity, resulting in the remaining processing resources being unable to meet the demand for processing resources of the second activity, causing the second activity to compete for limited processing resources. Therefore, it is necessary to design a resource allocation method for the processing unit to reasonably balance the contradiction between the resource requirements of the first activity and the second activity and eliminate the resource competition between the second activities.

[0049] To this end, an embodiment of the present application provides a method for allocating resources of a processing unit, which can be applied to a server. The processing unit can be a CP (central processor), and the first activity can be a high-pressure activity that requires more processing resources.

[0050] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] See also Figure 1 , which is a flow chart of a resource allocation method provided in an embodiment of the present application.

[0052] S101: Determine a first resource usage rate. The first resource usage rate is a ratio of a processing resource used by a first activity set, where the first activity set includes at least one first activity.

[0053] In one embodiment of the present application, it can be applied to a server. The first resource utilization rate can be determined by calling the RMFⅢ interface of the server, obtaining an XML format file containing processing resource utilization data of the first activity set, reading the file to obtain the number of processing resources used by the first activity set, and determining the proportion of processing resources used by the first activity set based on the total amount of processing resources, that is, the first resource utilization rate.

[0054] In one embodiment of the present application, the total amount of processing resources may be pre-set according to the operating environment of the activity.

[0055] In one embodiment of the present application, the first activity may be a high-stress activity that requires more processing resources.

[0056] S102: Obtain a resource idle rate according to a difference between the total amount of processing resources and the first resource usage rate.

[0057] In one embodiment of the present application, the resource idle rate may be:

[0058] %s=1-%u f

[0059] Among them, %s is the resource idle rate, %u f is the first resource utilization rate.

[0060] In another embodiment of the present application, a portion of idle processing resources may be reserved. If the utilization rate of the reserved idle processing resources is Δu=5%, the resource idle rate may be:

[0061] %s=1-%u f -△u

[0062] Among them, %s is the resource idle rate, %u f is the first resource utilization rate.

[0063] S103: Determine a second rated usage rate based on a larger value between a resource idle rate and a first rated usage rate, wherein the first rated usage rate is a maximum proportion of processing resources that can be used by a preset second activity set, and the second rated usage rate is a maximum proportion of processing resources that can actually be used by the second activity set, and the second activity set includes at least one second activity.

[0064] In an embodiment of the present application, the second rated usage rate may be a larger value between the resource idle rate and the first rated usage rate.

[0065] When the resource idle rate is greater than the first rated usage rate, it indicates that the processing resources allocated to the first activity will be wasted according to the preset threshold, and therefore the maximum threshold of the processing resources actually usable by the second activity set needs to be changed.

[0066] When the resource idle rate is less than the first rated usage rate, it means that the ratio of the maximum processing resources that can be used by the second activity set is reached according to the preset threshold, and therefore the processing resources occupied by the first activity need to be processed.

[0067] Among them, an optional embodiment can be seen in Figure 2 As shown:

[0068] S201: Determine a second resource usage rate according to a difference between the total amount of processing resources and the second rated usage rate.

[0069] In one embodiment, the second resource usage rate is:

[0070] %u s =1-%r2

[0071] Among them, %u s is the second resource utilization rate, and %r2 is the second rated utilization rate.

[0072] In another embodiment, a portion of idle processing resources may be reserved. If the utilization rate of the reserved idle processing resources is Δu=5%, the second resource utilization rate is:

[0073] %u s =1-%r2-△u

[0074] Among them, %u s is the second resource utilization rate, and %r2 is the second rated utilization rate.

[0075] S202: Process the first activity set using processing resources at a second resource usage rate.

[0076] In one embodiment, all first activities in the first activity set are processed according to the processing resource amount corresponding to the processing resource of the second resource usage rate.

[0077] S104: Process at least one second activity in the second activity set using processing resources that do not exceed the second rated usage rate.

[0078] In one embodiment of the present application, using processing resources that do not exceed the second rated usage rate to process at least one second activity in the second activity set may be:

[0079] A third resource usage rate is obtained, where the third resource usage rate is the sum of third sub-resource usage rates corresponding to each second activity in the second activity set, and the third sub-resource usage rate is a proportion of processing resources required to be used by the second activity.

[0080] In one embodiment, the execution entity may be a server, and obtaining the third resource utilization rate may be: calling the RMFⅢ interface of the server, obtaining an XML format file containing processing resource utilization rate data of the second activity set, reading the file to obtain the processing resources corresponding to each second activity in the second activity set, determining the corresponding resource utilization rates according to the total amount of processing resources, recording the resource utilization rate corresponding to each second activity as the third sub-resource utilization rate, and the sum of all third sub-resource utilization rates as the third resource utilization rate.

[0081] If the third resource usage rate is equal to the second rated usage rate, the third sub-resource usage rate of at least one second activity in the second activity set is lowered.

[0082] In one embodiment, when the third resource usage rate is less than the second rated usage rate, it can be considered that no resource contention occurs, and there is no need to process the second activity in the second activity set; when the third resource usage rate is equal to the second rated usage rate, it is considered that resource contention occurs, and the third sub-resource usage rate of at least one second activity in the second activity set is lowered.

[0083] In one embodiment, lowering the third sub-resource usage rate of at least one second activity in the second activity set may be:

[0084] A first number corresponding to the second activity is determined, where the first number is the number of processing units corresponding to the second activity.

[0085] determining a target number according to the first number, the target number being smaller than the first number;

[0086] The second activity is processed according to the target number of processing units, and a fourth sub-resource usage rate of the second activity is determined, wherein the fourth sub-resource usage rate of the second activity is lower than the third sub-resource usage rate.

[0087] In one embodiment, determining the target number according to the first number may be:

[0088] Let the undetermined number be the value of the first number minus 1;

[0089] Processing the second activity with the to-be-determined number of processing units, and determining an actual sub-resource usage rate of the second activity;

[0090] Determine whether the actual sub-resource usage rate of the second activity is lower than the third sub-resource usage rate. If so, use the actual sub-resource usage rate as the fourth sub-resource usage rate; if not, use the value of the first number minus 2 as the pending number, and execute subsequent steps until the actual sub-resource usage rate of the second activity is lower than the third sub-resource usage rate.

[0091] In another embodiment, lowering the third sub-resource usage rate of at least one second activity in the second activity set may be:

[0092] Use the server program to define a first-in-first-out queue q, denoted as q=(), which is used to increase or decrease the number of processing resources configured for the second activity set. When the second activity enters the queue, the server MVS interface is called to reduce the number of processing resources for the second activity by 1. When the second activity leaves the queue, the number of processing resources for the second activity is increased by 1.

[0093] Figure 3 A schematic diagram of a queue used to adjust resource usage of a second activity in a second activity set.

[0094] The N second activities included in the second activity set are denoted as P1, P2, P3...P N-1 ,P N , obtain the processing resource utilization data of these second activities in real time, which are recorded as %u1, %u2, %u3...%u N-1 ,%u N , calculate the difference △ug between the processing resource utilization rate of the second activity set and the second rated utilization rate %r2, the formula is:

[0095] △ug=%r2-∑%u i

[0096] When ∆ug=0, it indicates that there is resource contention in the second activity set, and the queue operation should be executed to process the second activity with the highest resource utilization rate Max(%u i ) corresponds to the second activity P i Perform the queue operation, and reduce the number of processing resources of the second activity in the queue by 1. At this time, the queue is q = (P i ).

[0097] When △ug>0, it means that there is no resource contention in the second activity set, and the dequeue operation should be executed to dequeue the queue q once. At this time, the length of the queue q is reduced by 1, and the number of second activity processing resources popped out is increased by 1.

[0098] The above process is automatically controlled by the server program without human intervention and can be cycled during the activity. The cycle time interval can be set to △t=20s.
