Technical Field

Background

As computing services scale up, systems providing support therefor evolve into a server-cluster model. For example, a cluster system providing cluster analysis services is a group of mutually independent computers interconnected by a high-speed network. The individual computers in the cluster system may be referred to as individual nodes and may include a management node and several computing nodes. The management node is used for scheduling each task, and the computing node is used for applying for the tasks from the management node, analyzing and processing the tasks distributed by the management node, and reporting the running state of the processed tasks at regular time.

When the management node schedules the various tasks, each task may be assigned the resources it uses in the compute node. The resources used by each task in the computing node are set by workers according to experience and are stored in the management node. Because the artificially set resources have certain errors, for example, the set resources are too high or too low, and the utilization rate of the resources of the computing nodes is reduced. Therefore, after a task is acquired by a compute node, a correction method is needed to correct the allocated resources for processing the task.

Detailed Description

In order to improve the utilization rate of resources of a computing node, embodiments of the present application provide a method and an apparatus for correcting task resources of a cluster system.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the present application, the cluster system is a group of mutually independent computers interconnected through a high-speed network, and each computer in the cluster system may be referred to as each node, and may include one management node and several computing nodes. The management node is used for scheduling each task, and the computing node is used for applying for the tasks from the management node, analyzing and processing the tasks distributed by the management node, and reporting the running state of the processed tasks at regular time.

As shown in fig. 1, an embodiment of the present application provides a method for correcting task resources of a cluster system, which is applied to a computing node in the cluster system, and the method includes:

s101, acquiring preset task resources and task attributes of the tasks to be processed, and taking the task attributes as the task attributes to be matched.

Specifically, in the embodiment of the present application, the computing node may obtain the preset task resource and the task attribute of the task to be processed by using the following method:

in this embodiment of the present application, the compute node may send a task application request to the management node, so that the management node sends task description information of a task to be processed to the compute node after responding to the task application request. The management node can package the task description information into a message and send the message to the computing node, and the task description information comprises preset task resources and task identifiers. That is, after the computing node receives the task description information sent by the management node, the preset task resource and the task identifier in the task description information can be obtained by analyzing the task description information. And then the computing node can acquire the task to be processed represented by the task identifier, and acquire the task attribute of the task to be processed by decoding the task to be processed.

The preset task resources are set by workers according to experience and are stored in the management node, so that when the management node schedules the tasks to be processed, the preset task resources are set as resources used for processing the tasks to be processed. The task attribute of the task to be processed refers to parameter information of the task to be processed, and can reflect the characteristics of the task to be processed, for example, the task attribute may be the type of the task to be processed, the amount of data to be processed, when the task to be processed is a task related to a video image, the task attribute may also be the resolution of the video image to be processed, and the like.

In the embodiment of the present application, the task attribute of the task to be processed may be used as the task attribute to be matched.

And S102, matching the task attribute to be matched with the task attribute in the preset task resource table.

The task resource table comprises a plurality of task attributes and standard task resources corresponding to the plurality of task attributes respectively, wherein the standard task resources are resources required when tasks with different task attributes are processed and are obtained through historical tests or calculations.

The task attribute can reflect the characteristics of the task to be processed, so when the task to be processed with different task attributes is completed, the task resources required to be used are different. For example, the task attribute may be different resolutions of the video image to be processed, and when the resolution is high, more task resources, such as more memories, are correspondingly required to complete the task to be processed; when the resolution is low, the task to be processed can be completed only by correspondingly needing less task resources.

In the embodiment of the invention, the sample task or the actual task with different task attributes can be adopted in advance for testing or calculation, so that the task resource which is actually needed when the task with different task attributes is completed is determined, and the task resource can be used as a standard task resource.

And performing corresponding test or calculation aiming at each task attribute in advance to obtain the standard task resource corresponding to each task attribute so as to form a task resource table. In the task resource table, standard task resources corresponding to each task attribute may be recorded.

In this embodiment of the present application, the computing node may sequentially match the task attribute to be matched with the task attribute in the task resource table, and determine whether a task attribute matched with the task attribute to be matched exists in the task resource table. For example, the task attribute in the task resource table may be a resolution of the task, and different resolutions correspond to standard task resources, that is, the acquired task attribute to be matched may be a resolution to be matched, and then the resolution to be matched may be matched with the resolution in the task resource table.

In this embodiment of the present application, a preset task resource table may be stored in a memory of a management node, and after a computing node is started, the task resource table may be directly downloaded from the management node and stored in the memory of the computing node. If the task resource table stored in the management node is updated, the version number of the updated task resource table is changed. The management node can send the version number of the preset task resource table to the computing node at regular time, the computing node can compare the received version number of the task resource table with the version number of the task resource table stored in the memory of the computing node, if the version number of the task resource table is not consistent with the version number of the task resource table stored in the memory of the computing node, the task resource table stored in the management node is the updated task resource table, the computing node can directly download the updated task resource table from the management node, and the task resource table before updating is deleted.

S103, if the task attribute matched with the task attribute to be matched exists in the task resource table, comparing the standard task resource corresponding to the matched task attribute with the preset task resource.

In this embodiment of the present application, since the task attribute in the task resource table corresponds to the standard task resource, the computing node may compare the standard task resource corresponding to the matched task attribute with the preset task resource to determine whether the preset task resource is the standard task resource of the task to be processed.

And S104, if the standard task resource corresponding to the matched task attribute is not equal to the preset task resource, uploading the standard task resource corresponding to the matched task attribute to a management node in the cluster system, so that the management node updates the preset task resource to the standard task resource corresponding to the matched task attribute.

The standard task resource is not equal to the preset task resource, and may be larger or smaller than the preset task resource.

And when the standard task resource is larger than the preset task resource, the distributed preset task resource is less than the standard task resource corresponding to the matched task attribute in the task resource table. That is, when the task to be processed is processed by using the preset task resource, various problems such as abnormal operation and the like may be caused due to insufficient resources. For example, the predetermined task resource may be allocated memory 50M, and the standard task resource may be allocated memory 60M. Obviously, the standard task resources are larger than the preset task resources, and the allocated preset task resources are not enough to execute the task to be processed.

And when the standard task resource is smaller than the preset task resource, indicating that the allocated preset task resource is more than the standard task resource corresponding to the matched task attribute in the task resource table. The task to be processed can be normally executed, but the resource is wasted to a certain extent. For example, the predetermined task resource may be allocated memory 50M, and the standard task resource may be allocated memory 40M. Obviously, the standard task resources are smaller than the preset task resources, and the allocated preset task resources are enough to execute the task to be processed, but cause memory waste.

Therefore, in the embodiment of the present application, if the standard task resource corresponding to the matched task attribute is not equal to the preset task resource, the computing node uploads the standard task resource corresponding to the matched task attribute to the management node in the cluster system, so that the management node updates the preset task resource to the standard task resource corresponding to the matched task attribute. That is, when the management node schedules the to-be-processed task next time, the standard task resource corresponding to the matched task attribute may be sent to the computing node as a resource used when the to-be-processed task runs in the computing node, so as to ensure that the to-be-processed task can run normally in the computing node, and ensure effective use of the resource. Meanwhile, the computing node may receive a task deletion request sent by the management node, and delete the to-be-processed task by responding to the received task deletion request.

The method for correcting task resources of a cluster system provided in the embodiments of the present application may search, in a preset task resource table, standard task resources used by a task to be processed in a compute node based on task attribute information of the task to be processed, compare the standard task resources with preset task resources,

if the standard task resource and the standard task resource are not equal, the standard task resource is uploaded to the management node, so that the management node updates the preset task resource to the standard task resource, the condition that certain errors exist in the manually set task resource is avoided, and the utilization rate of the resource of the computing node is further improved.

With reference to the foregoing embodiment, in practical applications, a computing node may only be capable of normally executing a task to be processed under some conditions, so that, optionally, in the method for correcting task resources of a cluster system provided in the embodiment of the present invention, if a standard task resource corresponding to a matched task attribute is not equal to a preset task resource, S104, uploading the standard task resource corresponding to the matched task attribute to a management node in the cluster system, may include:

and if the standard task resource corresponding to the matched task attribute is larger than the preset task resource, uploading the standard task resource corresponding to the matched task attribute to a management node in the cluster system.

And if the standard task resource corresponding to the matched task attribute is larger than the preset task resource, indicating that the allocated preset task resource is not enough to execute the task to be processed. Only in this case, the standard task resource corresponding to the matched task attribute needs to be uploaded to the management node in the cluster system.
