Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.

A user side submits a job task of an Application program, such as a Map reduce program, to a resource manager, which creates an Application Manager (AM) for the Application, and the Application manager is used for managing the Application program, including applying for resources, releasing resources, scheduling resources, and the like for the Application in a cluster.

The application manager sends a resource scheduling request for an application to the resource manager, the resource scheduling request generally includes a resource amount (such as a 100G memory) for a job task, and after the resource manager allocates a resource applied in the resource scheduling request to the application manager, the application manager communicates with a corresponding resource node to start the corresponding task. In the above process, when a range type resource is needed in the execution process of a job task, for example, a port, a graphics card, or a network card, etc., the resource manager may only allocate a certain number of ports, graphics cards, or network cards to the application manager, the port, graphics card, or network card allocated to the application manager by the resource manager may not be used by the job task, and after the port, graphics card, or network card is allocated to the job task, other job tasks or applications cannot use the graphics card, port, or network card, which also reduces the utilization rate of the resource.

Based on the above research, the present disclosure provides a resource scheduling method, where a resource type involved includes at least one range type resource, a resource amount corresponding to the range type resource is a range type resource amount, the range type resource amount includes an identification number range corresponding to the range type resource, a resource scheduling request sent by a client is received, the resource scheduling request includes at least one resource type and a corresponding resource amount required for executing a target task, allocable resource information reported by each of a plurality of resource nodes in a resource management system is received, and based on the resource type and the resource amount in the resource scheduling request and allocable resource information of the plurality of resource nodes, at least one target resource node is determined from the plurality of resource nodes; and sending the node identification of the searched target resource node, the matched resource type and the resource amount to an application manager corresponding to the client. Therefore, the range type resource with the identification number range meeting the scheduling requirement is distributed to the target task, and the complex scheduling requirement for the range type resource in the task execution process can be met.

It should be noted that the discovery process of the above-mentioned problems and the solution proposed by the present disclosure in the following to the above-mentioned problems should be the contribution of the inventor to the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

To facilitate understanding of the present embodiment, first, a resource scheduling method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the resource scheduling method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: a terminal device, which may be a User Equipment (UE), a mobile device, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle mounted device, a wearable device, or a server or other processing device. In some possible implementations, the resource scheduling method may be implemented by a processor calling computer readable instructions stored in a memory.

The following describes a method for monitoring a resource scheduling method provided by the embodiment of the present disclosure by taking an execution subject as a resource manager as an example.

Referring to fig. 1, which is a flowchart of a resource scheduling method provided in the embodiment of the present disclosure, in a resource manager, the resource scheduling method of the present disclosure is applied, where the resource manager manages a plurality of resource nodes, and each resource node manages at least one range type resource and a corresponding resource amount; may include the steps of:

s101, a resource manager receives a resource scheduling request sent by a client; the resource scheduling request comprises at least one resource type and corresponding resource amount required by executing the target task; the resource type comprises at least one range type resource, and the resource amount corresponding to the range type resource is the range type resource amount; the scope type resource amount comprises an identification number scope corresponding to the scope type resource.

Here, the target task may be a computing task, a processing task, or the like in a distributed computing application; the format of the resource scheduling request can be determined according to the actual application scene; the range type resource may include resources such as a port, a video card, and a network card, and the resource amount corresponding to the range type resource may be represented by the identification number range represented by the closed interval, for example, when the range type resource is a port, the corresponding resource amount may be represented as [1,50 ].

In a specific implementation process, after an application manager in the YARN cluster is started, the application manager sends a resource scheduling request for a target task in an application to the resource manager, where the resource scheduling request may request resources of at least one resource type, and when the application manager requests to schedule resources, the application manager may send multiple containers for the target task to the resource manager, where each container specifies a different resource type, and a resource scheduling request may apply for a target task to satisfy multiple range types of resources.

S102, receiving allocable resource information reported by each resource node in a plurality of resource nodes in the resource management system, wherein the allocable resource information comprises resource types and allocable resource amounts of allocable resources, and the allocable resource amounts comprise allocable range type resource amounts.

Resource nodes in the resource management system may periodically communicate with the resource manager, that is, the resource nodes report resource types of allocable resources (that is, resource types of unoccupied resources) managed by the resource nodes and allocable range type resource amounts (that is, available range type resource amounts) corresponding to the allocable resources to the resource manager, where the allocable range type resource amounts may also pass through an identification number range represented by a closed interval, and examples may refer to the foregoing, which is not illustrated here.

After receiving the heartbeat of each resource node, the resource manager correspondingly stores the resource types and the resource amounts of the allocable resources of the resource nodes so as to perform subsequent query. It should be noted here that the resource manager also stores all resource types and corresponding total resource amounts of the resource nodes, and occupied resource types and corresponding resource amounts, which are not described in detail herein.

S103, determining at least one target resource node from the plurality of resource nodes based on the resource type and the resource amount in the resource scheduling request and the allocable resource information of the plurality of resource nodes; wherein, each target resource node has allocable resources which are matched with the resource type and the resource amount in the resource scheduling request.

Here, the allocable resource represents a resource that does not perform a task, that is, a resource that is not occupied by an application program, and the allocable resource may be a memory, a processor, a graphics card, a port, a network card, or the like, and the allocable range type resource includes a port, a network card, a graphics card, or the like.

In S103, first, a current resource node is determined from a plurality of resource nodes, and it is determined whether allocable resources of the current resource node include allocable range type resources that match the range type resources in the resource scheduling request.

If yes, judging whether the identification number range indicated by the allocable range type resource quantity corresponding to the allocable range type resource in the allocable resource is larger than or equal to the identification number range indicated by the range type resource quantity of the range type resource in the resource scheduling request.

If so, that is, if the identification number range indicated by the allocable range type resource amount corresponding to the allocable range type resource in the allocable resource is greater than or equal to the identification number range indicated by the range type resource amount of the range type resource in the resource scheduling request, taking the current resource node as a target resource node for providing the resource of the resource type.

If the identification number range of the allocable range type resource quantity indication corresponding to the allocable range type resource in the allocable resource is smaller than the identification number range of the range type resource quantity indication of the range type resource in the resource scheduling request, determining a next resource node from the plurality of resource nodes, taking the next resource node as a current resource node, returning to execute the step of judging whether the allocable resource of the current resource node comprises the allocable range type resource matched with the range type resource in the resource scheduling request until a target resource node meeting the condition is determined, or determining that the resource of the resource type cannot be allocated until all the resource nodes do not meet the condition.

Here, the resource type of the allocable resource includes a resource type of a range type resource in the resource scheduling request, and the identifier range indicated by the allocable range type resource amount corresponding to the allocable range type resource in the allocable resource is greater than or equal to the identifier range indicated by the range type resource amount of the range type resource in the resource scheduling request.

In a specific implementation process, after the resource manager receives a resource scheduling request of the application manager for a target application, one resource node identifier may be selected arbitrarily from a plurality of resource node identifiers stored by the resource manager, or one resource node identifier may be selected according to a storage sequence of the plurality of resource node identifiers in the resource manager, and a resource node corresponding to the selected resource node identifier is used as a current resource node.

The resource manager compares, for each container in the resource scheduling request, the range type resource of the resource type specified by the container with the allocable range type resource of the current resource node, that is, compares the resource type of the resource type specified by the container with the allocable range type resource of the current resource node.

The allocable range type resource of the current resource node includes a range type resource in the container, that is, the resource type in the resource type of the allocable resource of the current resource node is the same as the resource type in the container, and further, the identifier range indicated by the allocable range type resource amount corresponding to the allocable range type resource of the allocable resource is compared with the identifier range indicated by the range type resource amount in the resource scheduling request.

When the identification number range indicated by the allocable range type resource amount corresponding to the allocable range type resource of the allocable resource is greater than or equal to the identification number range indicated by the range type resource amount in the resource scheduling request, that is, the identification number range indicated by the allocable range type resource amount corresponding to the allocable range type resource of the allocable resource includes the identification number range indicated by the range type resource amount in the resource scheduling request, the current resource node may be used as the target resource node.

If the resource type of the allocable range type resource of the current resource node does not include the resource type in the container, that is, if the resource type of the allocable range type resource of the current resource node is not the same as the resource type in the container, determining a resource node from the multiple resource nodes as the current resource node, and returning to perform the step of judging whether the allocable resource of the current resource node includes the allocable range type resource matched with the range type resource in the resource scheduling request until a target resource node meeting the condition is determined, and if all the resource nodes do not meet the condition, determining that the resource of the resource type cannot be allocated, and ending the target task.

When the identification number range of the allocable range type resource quantity indication corresponding to the allocable range type resource of the allocable resource is smaller than the identification number range of the range type resource quantity indication in the resource scheduling request, that is, the identification number range of the allocable range type resource quantity indication corresponding to the allocable range type resource of the allocable resource does not include the identification number range of the range type resource quantity indication in the resource scheduling request, that is, a part of identification number or no identification number exists in the identification number range of the allocable range type resource quantity indication corresponding to the allocable range type resource of the allocable resource, and the identification number in the identification number range of the range type resource quantity indication in the resource scheduling request is the same, determining the next resource node from the resource nodes, using the next resource node as the current resource node, and returning to execute the judgment of whether the allocable resource of the current resource node includes the range type resource in the resource scheduling request or not And the step of allocating the scope type resource matched with the type resource until a target resource node capable of meeting the condition is determined.

For example, taking an example that a resource manager searches for a matched resource in a resource node as an example to explain, allocable resources managed in a resource node 1 are port number 1-2000 and graphics card number 1-10, a resource scheduling request received by the resource manager includes 2 containers, resource types specified in the container 1 are port and graphics card, a range type resource amount of the port is [1000,2000], a range type resource amount of the graphics card is [1,2], resource types specified in the container 2 are port and graphics card, a range type resource amount of the port is [8000,9000], the port number 1-2000 and the graphics card number 1-10 in the resource node 1 can meet requirements of the container 1 (port number 1000-2000 and graphics card number 1-2), that is, the idle port number 1000-2000 in the resource node 1 is the same as the port number applied in the container 1, the numbers 1 and 2 of the idle graphics cards in the resource node 1 are the same as the numbers of the graphics cards applied in the container 1, and then the resource node 1 is determined as the target resource node, but the resource node 1 does not have the resource matching with the resource type and range type resource amount in the container 2, and the allocable resource meeting the container 2 needs to be inquired in other resource nodes, which is not described in detail herein.

When the target task is finished, all the determined resource nodes do not meet the condition, that is, no resource node can meet the resource scheduling request, so that the resource of the resource type cannot be allocated to the target task, and the target task is finished.

And S104, the resource manager sends the node identification of the searched target resource node, the matched resource type and the resource amount to the application manager corresponding to the client.

Here, the node identifier may be a node code, a node name, or the like, and may be determined according to actual situations.

In a specific implementation process, because one resource scheduling request received by the resource manager includes a plurality of containers, the resource manager sequentially allocates resources for each container, and after the resource manager queries allocable resources matched with the container from any resource node, the resource manager sends the node identifier of the target resource node where the searched allocable resources are located, and the resource type and the resource amount matched with the container to the application manager.

For example, continuing with the example in step S103, if the allocable resource of the resource in the resource node 1 matches the resource type (port number 1000-2000) and the scope type resource amount (graphics card number 1-2) of the container 1, the node identifier is the resource node 1, the identification number scope [1000,2000] of the port, and the identification number scope [1,2] of the graphics card, and is sent to the application manager.

The resource manager also maintains the use state of the range type resource in each resource node while carrying out resource scheduling on the target task, wherein the use state comprises an idle state and an occupied state, the idle state represents that the resource does not execute the task, and the occupied state represents that the resource is executing the task.

After the resource manager allocates the matched allocable resource to the target task, the use state of the matched allocable resource stored by the resource manager is changed from an idle state to an occupied state, so that the resource manager can conveniently allocate the range type resource to other containers in the resource scheduling request or allocate the range type resource to other applications, and resource conflict is avoided.

For example, continuing the previous example, taking the node identification as NM1, the range type resource amount of the port as [1000,2000], and the range type resource amount of the graphics card as [1,2] as an example, the resource manager maintains the resource state table before allocating resources as shown in table 1:

watch 1

After the resource manager sends the node identifier NM1, the range type resource amount of the port [1000,2000], and the range type resource amount of the graphics card [1,2] to the application manager, the resource manager updates the use state of the corresponding resource in the maintained resource state table, as shown in table two:

watch two

When the resource manager determines that the resource allocated to the application manager and matching with the resource type and the resource amount in the resource scheduling request is released (the release process is described in detail below), the resource manager further changes the usage state of the released resource from the occupied state to the idle state.

For example, continuing the previous example, after the port with port number [1000,2000] and the graphics card with graphics card number [1,2] in NM1 are released, the resource manager updates the state table, and the updated table refers to table 1.

After the resource manager allocates resources (e.g., a port with a range type resource amount of [8000,9000 ]) in the resource node to the application manager, the resource manager increases the number of occupied resources of the queue where the target task is located and the number of occupied resources corresponding to the target task. For example, a queue where the target task is currently occupies 1000 ports and 500 ports, and then after the target task is allocated to 1000 ports, the number of resources of the ports occupied by the queue is: the 1000+1000 equals 2000, and the number of resources of the port occupied by the target task equals 1000+500 equals 1500.

After receiving the node identifier of the resource node and the matched resource type and resource amount sent by the resource manager, the application manager further communicates with the resource node, and a method for the application manager to communicate with the resource node is described in detail below.

In a method for scheduling resources provided in an embodiment of the present disclosure, referring to fig. 2, the method is applied in an application manager, and may include the following steps:

s201, an application manager sends a resource scheduling request aiming at a target task to a resource manager; the resource scheduling request carries at least one resource type and corresponding resource amount required by executing the target task; the resource type comprises at least one range type resource, and the resource amount corresponding to the range type resource is the range type resource amount; the scope type resource amount comprises an identification number scope corresponding to the scope type resource.

Reference may be made to the description of step S101 for the resource scheduling request, which is not described here.

S202, an application manager receives a node identifier of at least one target resource node sent by the resource manager, and a matched resource type and resource amount; and the resource scheduling request comprises a resource type and a resource amount, wherein the resource type and the resource amount in the resource scheduling request are matched with the allocable resources in the resources managed by each target resource node.

Reference may be made to the description of step S104 for the resource scheduling request, which is not described here.

S203, the application manager sends a resource use request to the target resource node; the resource use request carries a task processing instruction associated with a target task, and a resource type and a corresponding resource amount required by responding to the task processing instruction.

Here, the format of the resource use request may be determined according to actual conditions, and the task processing instruction is used to process data in the target task operation process; the resource type and the corresponding resource amount can be referred to above.

In a specific implementation process, after receiving the node identifier of the target resource node and the matched resource type and resource amount, the application manager sends the task processing instruction associated with the target task, the resource type required by the response task processing instruction and the corresponding resource to the target resource node.

For example, after receiving the node identifier NM1, the scope type resource amount of the port being [1000,2000], and the scope type resource amount of the graphics card being [1,2], the application manager sends a task processing instruction associated with the target task to NM1, and the scope type resource amounts of the port being the resource type, the port being [1000,2000], and the graphics card being the resource types being [1,2 ].

After receiving the resource usage request sent by the application manager, the resource node responds to the task processing instruction carried in the resource usage request, which may be referred to as the following.

The present disclosure provides a resource scheduling method, as shown in fig. 3, the method is applied in a resource node, and may include the following steps:

s301, a resource node receives a resource use request aiming at a target task, which is sent by an application manager; the resource use request carries a task processing instruction associated with a target task, and a resource type and a corresponding resource amount required by responding to the task processing instruction; the resource type comprises at least one range type resource, and the resource amount corresponding to the range type resource is the range type resource amount; the scope type resource amount comprises an identification number scope corresponding to the scope type resource.

Here, the task processing instruction, and the resource type and the resource amount of the resource required by responding to the task processing instruction may refer to the above, which is not described herein again.

S302, the resource node searches for the unoccupied allocable resources which are matched with the resource type and the resource amount in the resource scheduling request from the resources managed by the resource node based on the resource type and the resource amount in the resource scheduling request;

in a specific implementation process, after receiving a resource usage request of an application manager for a target application, a resource node compares a resource type carried in the resource usage request with an allocable resource managed by the resource node, and if the allocable resource managed by the resource node is matched with the resource type carried in the resource usage request, that is, if the resource type in the resource type of the allocable resource managed by the resource node is the same as the resource type carried in the resource usage request, compares an identification number range indicated by a resource type resource amount of the resource type carried in the resource usage request with an identification number range indicated by an allocable range type resource amount of the allocable resource managed by the resource node.

If the identification number range indicated by the resource type range type resource amount carried in the resource use request is matched with the identification number range indicated by the allocable range type resource amount of the allocable resource managed by the resource use request, that is, if the identification number range indicated by the allocable range type resource amount of the allocable resource managed by the resource use request includes the identification number range indicated by the resource type range type resource amount carried in the resource use request, whether the use state of the corresponding resource is an idle state is judged.

And S303, the resource node responds to the task processing instruction based on the searched distributable resource.

In a specific implementation process, after the resource node queries the allocable resources which are matched with the resource types and the resource amounts in the resource scheduling request and have the use states of the allocable resources in the idle state, the task processing instruction is responded based on the queried allocable resources.

After the resource node finds the allocable resource which is matched with the resource type and the resource amount in the resource scheduling request and has the use state of the idle state, the resource node can also update the state of the resource in the resource state table maintained by the resource node, namely, the found use state of the allocable resource is changed from the idle state to the occupied state.

For example, the application manager sends a resource usage request to the resource node 1, where the carried resource type is a port, the range type resource amount of the port is [1000,2000], the resource type is a graphics card, and the range type resource amount of the graphics card is [1,2], and a change example of states of the port number 1000-2000 and the graphics card numbers 1 and 2 maintained in the resource node 1 is described, where information included in the resource state table is not illustrated here, and before searching for a resource, the maintained resource state table is shown in table three:

watch III

Resource type	Amount of scope type resource	State of use
			Port(s)	[1000,2000]	Idle state
Display card	[1,2]	Idle state

After the resource node 1 finds the allocable resource, the resource node 1 updates the use state of the corresponding resource in the maintained resource state table, as shown in table four:

watch four

Resource type	Amount of scope type resource	State of use
			Port(s)	[1000,2000]	Occupancy state
Display card	[1,2]	Occupancy state

The resource node maintains the resource type and the range type resource amount, records the resource types of all the resources managed by the resource node and the corresponding total resource amount, the resource types of the used resources and the corresponding resource amount, and the resource types of the allocable resources (namely, idle resources) and the corresponding resource amount, and correspondingly changes the use states of the used resources and the use states of the unused resources after the resources in the resource node are allocated to the target task. For example, taking a port and a graphics card as an example for explanation, a resource node maintains 1000 ports and 2 graphics cards, the range type resource amount of a port is [1000,2000], the range type resource amount of a graphics card is [1,2], the range type resource amount of a used port is [1500,1700], the usage state is an occupied state, the range type resource amount of a used graphics card is 1, and the usage state is an occupied state, the range type resource amounts of idle ports are [1000,1499] and [1701,2000], the usage states corresponding to the idle ports [1000,1499] and [1701,2000] are respectively an idle state, the range type resource amount of an idle graphics card is 2, and the usage state is an idle state.

In the process that the resource node executes the target task based on the allocable resource, the application manager can actively request to release the resource for operating the target task, the resource node correspondingly changes the use state of the released resource, and if the application manager does not actively request to release the resource, the resource node can change the use state of the corresponding resource and update the range type resource amount of the idle range type resource after the resource use is finished, so that when the resource node sends a node jump to the resource manager, the resource node informs the resource manager of the resource type and the range type resource amount of the allocable resource, and the resource manager can conveniently allocate the resource to other applications or containers.

The following describes the process of the application manager actively releasing resources:

after the resource node responds to the task processing instruction based on the found allocable resource, the method may further include the following steps:

the resource node receives a resource release request sent by the application manager; the resource release request carries the resource type and the corresponding resource amount of the resource to be released; the resource amount of the resource to be released comprises the resource amount of the type of the range to be released; and changing the use state of the corresponding resource to be released from the occupied state to the idle state based on the resource type and the corresponding resource amount carried in the resource release request.

Here, the format of the resource release request may be determined according to an actual scenario; the amount of the resource of the to-be-released range type may be an identification number range represented by a closed interval, which may be referred to above.

In the specific implementation process, after receiving a resource release request which is sent by an application manager and carries a resource type of a resource to be released and a resource amount corresponding to the resource type, the resource node compares the resource type carried in the resource release request with the resource type managed by the resource node, if the resource type matched with the resource type carried in the resource release request is found in the resource type managed by the resource node, further compares the range type resource amount of the found resource type with the resource amount carried in the resource release request, and if the range type resource amount of the found resource type is greater than or equal to the resource amount carried in the resource release request, changes the use state of the found resource from an occupied state to an idle state.

For example, the application manager sends a resource release request to the resource node 1, where the resource type carried in the resource release request is a port, the range type resource amount of the port is [1000,2000], changes the usage states of the ports No. 1000 to No. 2000 maintained by the resource node from an occupied state to an idle state, and refers to table three in the updated resource state table.

After releasing the data processing resources, the resource node updates the use state of the released resources in the resource manager through the node heartbeat sent to the resource manager by the resource node.

In order to more clearly understand the disclosure, further details are provided below by way of another example.

As shown in fig. 4, a flowchart of a resource scheduling method provided in the embodiment of the present disclosure includes the following steps:

s401, an application manager sends a resource scheduling request aiming at a target task to a resource manager; the resource scheduling request carries at least one resource type and corresponding resource amount required by running the target application; the resource type comprises at least one range type resource, the resource amount corresponding to the range type resource is the range type resource amount, and the range type resource amount comprises the identification number range corresponding to the range type resource.

S402, the resource manager periodically receives the heartbeat reported by the resource node, that is, receives allocable resource information of the resource node, where the allocable resource information includes a resource type of the allocable resource and a corresponding allocable resource amount.

And S403, the resource manager determines a current resource node from the plurality of resource nodes, and queries allocable resources matched with the resource type and the corresponding resource amount from the resources managed by the current resource node based on the resource type and the corresponding resource amount in S401 and the allocable resource information of the current resource node.

If the matched allocable resource is found, the resource node to which the matched allocable resource belongs is taken as the target resource node, and S404 is executed.

If the matched allocable resource is not found, determining a next resource node from the plurality of resource nodes, taking the next node as the current resource node, and returning to the step S403.

S404, the resource manager sends the node identification of the at least one target resource node determined in S403, and the matched resource type and resource amount in each target resource node to the application manager.

S405, after receiving the node identifier of at least one target resource node and the matched resource type and resource amount sent by the resource manager, the application manager sends a resource use request for the target task to the target resource node, wherein the resource use request carries a task processing instruction associated with the target task, and the resource type and resource amount required by responding to the task processing instruction.

S406, the target resource node searches the unoccupied allocable resources matched with the resource type and the resource amount from the resources managed by the target resource node based on the resource type and the resource amount in the step S405, and responds to the task processing instruction based on the searched allocable resources.

S407, after the resource node finds the allocable resource which is matched with the resource type and the resource amount and is not occupied, the resource node changes the use state of the found allocable resource from the idle state to the occupied state.

S408, the application manager sends a resource release request to the target resource node; the resource release request carries the resource type and the corresponding resource amount of the resource to be released.

S409, the target resource node changes the corresponding resource to be released from the occupied state to the idle state based on the resource type and the corresponding resource amount in the S408.

It should be noted here that S402 may be executed after S401, or may be executed after any one of the above steps, the above example is only illustrative, and the present application does not limit the execution order of S402.
