When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects herein, as detailed in the appended claims.

The embodiment of the disclosure provides a method for controlling resource access. Referring to FIG. 1, FIG. 1 is a flow diagram illustrating a method of controlling resource access in accordance with an exemplary embodiment. The method is applied to a distributed system, and as shown in fig. 1, the method comprises the following steps:

in step S11, a resource request is received.

Step S12, determine the target job to which the task that initiated the resource request belongs.

In step S13, the resource allocation status of the target job is determined.

Step S14, if the resource allocation status does not meet the set resource allocation condition, rejecting the resource request.

In another embodiment, in step S14, if the resource allocation status meets the set resource allocation condition, the resource request is allowed.

The method comprises the steps of determining the resource allocation state of a target operation after receiving a resource request, rejecting the resource request when the resource allocation state does not accord with a set resource allocation condition, thereby refining the granularity of resource control to an operation level, and when a plurality of operations are submitted by a same user, one of the operations does not accord with the set resource allocation condition and other operations of the user cannot be influenced after the execution fails, so that the user can smoothly process as many operations as possible, and the operation processing efficiency is improved.

Fig. 2 is a system block diagram illustrating a method for controlling resource access by an application in accordance with an exemplary embodiment. The resource control center in fig. 2 is used to perform the above-described method. The resource control center may be a separate device or a function running in the master node. In the system, a client for serving a user submits a plurality of jobs of the user to a master node of a computer cluster, the master node decomposes each job into a plurality of tasks to be scheduled to a plurality of slave nodes in the computer cluster, the slave nodes submit resource requests to a resource control center before executing the tasks, and the resource control center allows or rejects the resource requests according to the method. After the resource control center allows the resource request, the slave node executes the corresponding task, and the resource pool records the resource amount of each resource type consumed by each task and reports the resource amount to the resource control center. After the resource control center refuses the resource request, the corresponding task fails to execute, or the task is paused for a period of time and then the resource request is reinitiated.

The embodiment of the disclosure also provides a method for controlling resource access. In this method, the resource allocation status of the target job includes at least one of:

the resource occupation amount corresponding to each resource type of the target operation, the resource available amount corresponding to each resource type of the target operation and the resource application amount corresponding to each resource type in the resource request;

the resource occupation amount corresponding to each resource type of the target operation is the sum of the resource occupation amounts corresponding to the corresponding resource types of all the tasks under the target operation; the resource available amount corresponding to each resource type of the target operation is the difference between the resource quota amount corresponding to each resource type of the target operation and the resource occupation amount corresponding to the corresponding resource type of the target operation.

The embodiment of the disclosure also provides a method for controlling resource access. Referring to fig. 3, fig. 3 is a flow diagram illustrating a method of controlling resource access in accordance with an example embodiment. In this method, step S13 in fig. 1 further includes a process of calculating a resource occupation amount corresponding to each resource type of the target job, where the process includes:

step S31, acquiring a one-to-many mapping relation between the target operation and all tasks under the target operation;

step S32, determining all tasks under the target operation according to the one-to-many mapping relation;

step S33, calculating the sum of the occupied resource amounts corresponding to the same resource type of all tasks under the target job.

When the resource control center is an independent device with the main node, the resource control center obtains the one-to-many mapping relation between the target operation and all tasks under the target operation from the main node. When the resource control center is a function running on the main node, the one-to-many mapping relation between the target job and all tasks under the target job is obtained from the job scheduling function of the main node.

In another embodiment, step S13 of fig. 1 further includes a process of calculating a resource availability corresponding to each resource type of the target job, where the process includes step S34: and calculating the difference between the resource quota amount corresponding to each resource type of the target operation and the resource occupation amount corresponding to the corresponding resource type of the target operation, and obtaining the resource available amount corresponding to each resource type of the target operation.

The embodiment of the disclosure also provides a method for controlling resource access. In the method, setting the resource allocation condition includes at least one of:

under the condition one, the sum of the resource occupation amount corresponding to one resource type of the target operation and the resource application amount corresponding to the same resource type in the resource request is less than or equal to the resource quota amount corresponding to the same resource type of the target operation;

a third condition is that the resource occupation amount corresponding to one resource type of the target operation is less than or equal to a first proportion of the resource quota amount corresponding to the same resource type of the target operation, and the first proportion is less than 1 and greater than 0;

the resource application amount corresponding to one resource type in the resource request is smaller than or equal to the resource available amount corresponding to the same resource type of the target operation;

the resource application amount corresponding to a resource type in the resource request is smaller than or equal to the resource quota amount corresponding to the same resource type of the target operation;

the sixth condition is that the available resource amount corresponding to a resource type of the target job is greater than or equal to a second proportion of the resource quota amount corresponding to the same resource type of the target job, and the second proportion is less than 1 and greater than 0.

In the method, the resource allocation condition may be configured and set by the administrator device, for example, the first configuration condition is the set resource allocation condition, for example, the second configuration condition is the set resource allocation condition, for example, the set of the first configuration condition and the second configuration condition is the set resource allocation condition, and so on.

The resource type in the method comprises at least one of the following: CPU usage (e.g., percentage of usage), memory resources, storage resources, network bandwidth, and various other resources that may be used in the network in addition to the types of resources described above.

Examples are as follows:

example one

User 1 initiates two jobs, specificallyjob 1 and job 2.

Thejob 1 includes 4 tasks, specifically,task 1, task 2, task 3, and task 4, and the resource usage of each task is shown in table 1:

TABLE 1

The slave node executing the task 4 initiates a resource request related to the task 4, wherein the resource request comprises: the resource application amount of the CPU resource percentage type is 12%, and the resource application amount of the memory resource is 100M.

The set resource allocation condition comprises a first condition, when thejob 1 is judged to be in accordance with the set resource allocation condition, according to the first condition, the sum of the resource occupation amount (12%) of the CPU resource percentage type of thejob 1 and the resource application amount (5%) of the CPU resource percentage type is 17% and is greater than the resource quota (10%) of the corresponding type, so that thejob 1 is judged to be in accordance with the set resource allocation condition.

And setting a resource allocation condition comprising a second condition, and judging whether thejob 1 meets the set resource allocation condition, wherein according to the second condition, the resource application amount (12%) of the CPU resource percentage type is greater than the quota amount (10%) of the CPU resource percentage type in the resource quota of thejob 1, so that thejob 1 is judged not to meet the set resource allocation condition.

And when the set resource allocation condition comprises a third condition, judging whether thejob 1 meets the set resource allocation condition, according to the third condition, the resource occupation amount (8%) corresponding to the CPU resource percentage type of thejob 1 is greater than the first proportion (7%) of the quota amount corresponding to the same resource type in the resource quota (10%) of thejob 1, so that thejob 1 is judged not to meet the set resource allocation condition.

Based on the determination thatjob 1 does not meet the set resource allocation condition, the resource request is rejected, task 4 ofjob 1 will fail to execute, and job 4 may also fail to execute, but job 2 still runs normally.

Example two:

user 1 initiates two jobs, specificallyjob 1 and job 2.

Job 1 includes 4 tasks, specificallytask 1, task 2, task 3, and task 4, and the resource usage of each task is shown in table 1.

The slave node executing the task 4 initiates a resource request of the task 4, wherein the resource request comprises: the resource application amount of the CPU resource percentage type is 12%, and the resource application amount of the memory resource is 100M.

Calculating the resource available quantity corresponding to each resource type of thejob 1 according to the quota quantity corresponding to each resource type of thejob 1, and obtaining the results shown in table 2:

TABLE 2

And setting a resource allocation condition comprising a condition four, and when judging whether thejob 1 meets the set resource allocation condition, according to the condition four, judging that thejob 1 does not meet the set resource allocation condition because the resource application amount (12%) of the CPU resource percentage type of thejob 1 is greater than the resource available amount (10%) of the CPU resource percentage type in the resource quota of thejob 1.

And when judging whether thejob 1 meets the set resource allocation condition, according to the condition five, the resource application amount (12%) of the CPU resource percentage type of thejob 1 is larger than the resource quota amount (2%) of the CPU resource percentage type in the resource quota of thejob 1, so that thejob 1 is judged not to meet the set resource allocation condition, and thejob 1 is judged not to meet the set resource allocation condition.

And when judging whether thejob 1 meets the set resource allocation condition, calculating the resource available quantity corresponding to each resource type of thejob 1 according to the quota quantity corresponding to each resource type of thejob 1 according to the condition six, and obtaining the result shown in the table 2. The resource available amount of the CPU resource percentage type ofjob 1, that is, 2%, is smaller than the second proportion (3%) of the quota amount of the CPU resource percentage type in the resource quota ofjob 1, that is, 10%, so it is determined thatjob 1 does not meet the set resource allocation condition.

Depending on the result of the determination, this resource request is denied and task 4 ofjob 1 will fail to execute, but job 2 will still run normally.

The embodiment of the disclosure also provides a method for controlling resource access.
