Fig. 1 is a flowchart of a task scheduling method provided in an embodiment of the present application, where the method is applied to a node in a task scheduling system, where the system includes at least two nodes, and as shown in fig. 1, the method includes:

101. and responding to a starting instruction, reading a main node record table and determining the main node state information in the task scheduling system, wherein the main node record table is used for recording the address information of the main node and the activity information of the main node in the task scheduling system, and the starting instruction is used for indicating the task to be processed.

Illustratively, when receiving a start instruction of a user, a node in the distributed task scheduling system reads a master node record table in response to the start instruction, and determines master node status information in the current task scheduling system, wherein the master node record table is configured in the system and is a file for recording address information of the master node in the task scheduling system and activity information of the master node, and the start instruction is used for indicating a task to be processed.

102. And if the master node state information represents that no master node exists in the task scheduling system currently or the master node is inactive, performing information entry processing on the master node record table.

Illustratively, if it is determined that a master node does not exist in the task scheduling system currently or the master node is in an inactive state in the task scheduling system currently through master node state information in the current task scheduling system, the information entry processing is performed on the master node record table. When the master node is in the inactive state, the master node record table may not have information updated for more than the preset time, or the information for representing the activity of the master node in the master node record table may be smaller than a preset threshold.

103. And if the information of the main node record table is determined to be successfully recorded, acquiring the tasks to be processed, and distributing the tasks to be processed to each task execution node in the system to execute the tasks to be processed.

For example, if it is determined that the information entry of the master node record table is successful, for example, the code identification information of the master node record table or the address information of the master node record table is successfully inserted into the master node record table, the to-be-processed task indicated in the start instruction may be loaded and acquired, and the to-be-processed task may be allocated to each task execution node in the system to execute the to-be-processed task.

In summary, the task scheduling method provided in this embodiment includes the following steps: responding to a starting instruction, reading a main node record table, and determining main node state information in the task scheduling system; if the fact that the main node does not exist in the main node state information representation task scheduling system or the main node is not active is determined, information input processing is conducted on a main node record table; and if the information of the main node record table is determined to be successfully recorded, acquiring the tasks to be processed, and distributing the tasks to be processed to each task execution node in the system to execute the tasks to be processed. The process can be realized by any node in the task scheduling system, and the task scheduling is not dependent on a certain node, so that the success rate and efficiency of task scheduling can be improved, and resources are saved.

Fig. 2 is a flowchart of another task scheduling method provided in an embodiment of the present application, where the method is applied to a node in a task scheduling system, where the system includes at least two nodes, and as shown in fig. 2, the method includes:

201. and responding to a starting instruction, reading a main node record table and determining the state information of the main node in the task scheduling system, wherein the main node record table is used for recording the address information of the main node and the activity information of the main node in the task scheduling system, and the starting instruction is used for indicating the task to be processed.

For example, this step is referred to as step 101, and is not described again.

202. And if the fact that the main node does not exist in the main node state information representation task scheduling system currently or the main node is not active is determined, information entry processing is carried out on the main node record table.

In one example, step 202 includes the steps of:

and if the master node record table is determined not to have the address information of the master node, recording the address information corresponding to the node into the master node record table.

Or if the update time interval of the address information of the master node in the master node record list is determined to be larger than the preset threshold value; the address information corresponding to the node is recorded into the record table of the master node.

Illustratively, if it is determined that the master node does not exist in the task scheduling system currently or the master node is in an inactive state in the task scheduling system currently by reading the master node state information in the master node record table, the information entry processing is performed on the master node record table. When the address information of the master node does not exist in the master node record table, the master node may be considered to be currently absent in the task scheduling system, and when the update time interval of the address information of the master node in the master node record table is greater than the preset threshold value, the master node may be considered to be currently inactive in the task scheduling system. The information entry processing is performed on the main node record table, the address information corresponding to the node itself may be entered into the main node record table, or the coding identification information of the node itself may be entered into the main node record table, so as to update the main node record table.

203. And if the information of the main node record list is determined to be successfully input, acquiring the task to be processed, and carrying out fragment processing on the task to be processed to generate N subtasks, wherein N is a positive integer greater than or equal to 1.

Illustratively, if the master node record table is authorized to be subjected to information entry and other nodes cannot modify and update the master node record table before, the master node record table can be subjected to information entry, if the master node record table is determined to be successfully entered, it is indicated that the node serves as a master node in the task scheduling at the moment, a task to be processed indicated in a starting instruction can be read, the task to be processed is loaded into a memory, the task to be processed is subjected to fragmentation processing, and N subtasks are generated, wherein N is a positive integer greater than or equal to 1.

204. And reading the node load information of each task execution node in the system, and distributing each subtask to each task execution node according to the node load information of each task execution node to execute the task to be processed.

In one example, step 204 includes the steps of:

determining the load difference among the task execution nodes according to the node load information of the task execution nodes;

Illustratively, when the node is determined as the master node in the task scheduling of this time, other nodes in the task scheduling system are automatically determined as task execution nodes at this time, and the master node reads the task execution nodes which are currently active in the task scheduling system and node load information of each task execution node at this time, and allocates each subtask to each task execution node according to the node load information of each task execution node to execute the task to be processed.

In one example, the load difference between the task execution nodes can be calculated and determined according to the node load information of the task execution nodes; and pre-distributing each subtask according to the load difference between each task execution node and the total task amount so as to complete the load difference of each task execution node, and evenly distributing the rest subtasks to the corresponding task execution nodes.

In one example, after each task execution node receives a corresponding subtask, a service thread for task execution may be started, the service thread may load the corresponding subtask into a memory, and the task thread may delegate the subtask to a service thread pool for execution; the business thread analyzes the arrangement relation of the subtasks, if the subtasks have dependent father tasks, whether the father tasks are executed or not is judged firstly, and if the father tasks are not executed, the father tasks are executed firstly; in the process, the business thread finds a corresponding task execution engine from the memory according to the type of the subtask, transmits the parameter of the subtask to the execution engine, and updates the execution state of the task after the execution engine is finished. The node serving as the master node also updates the execution information of each subtask, and modifies the state of each task to be executed.

In one example, in the task scheduling system, each node is equal, any node can acquire master node state information in the current system, and perform information entry operation on a master node record table according to the current master node state information to compete for a master node of the task scheduling, and when a certain node successfully enters its own information in the master node record table, the node is a master node of the task scheduling, and other nodes automatically become task execution nodes.

In summary, in this embodiment, if it is determined that the address information of the master node does not exist in the master node record table, or if it is determined that the update time interval of the address information of the master node in the master node record table is greater than the preset threshold, the address information corresponding to the node is recorded in the master node record table. The state of the current main node in the system can be more accurately confirmed, and then follow-up information entry can be effectively carried out according to the state information, the main node is competed, the efficiency of the task scheduling preparation step is improved, and the task scheduling efficiency is further improved. By fragmenting the tasks and performing balanced distribution on the subtasks into which the tasks to be processed are divided according to the load information of each task execution node, the task execution efficiency can be improved.

One or more embodiments of the present application may further include: and if the master node record table is determined to have the address information of the master node, and the update time interval of the address information of the master node in the master node record table is smaller than or equal to a preset threshold value, giving up information entry of the master node record table, and waiting for receiving and executing the task to be processed.

Exemplarily, if it is determined that address information of a master node exists in the master node record table and an update time interval of the address information of the master node in the master node record table is smaller than or equal to a preset threshold, it is determined that an effective master node exists in the task scheduling system at present and can perform task scheduling of this time, and the master node gives up information entry to the master node record table, automatically becomes a task execution node, waits for receiving and executes a task to be processed.

In summary, in this embodiment, if it is determined that there is an effective master node in the task scheduling system currently to perform the task scheduling of this time, the information entry to the master node record table is abandoned, and the master node record table automatically becomes a task execution node in the task scheduling of this time, so that the normal operation of the task scheduling system can be effectively ensured in this process.

One or more embodiments of the present application may further include: and if determining that the information entry of the main node record list fails, waiting for receiving and executing the task to be processed.

Exemplarily, when the node performs information entry on the master node record table, other nodes have successfully performed information entry on the master node record table, and at this time, the node does not have an authority to perform information entry on the master node record table, or cannot successfully perform information entry on the master node record table, and at this time, the node automatically becomes a task execution node in the task scheduling of this time, and waits for receiving and executing a task to be processed.

In summary, in the embodiment, the master node record table is set in an optimistic locking manner, so that only one node can perform information entry on the master node record table, and normal operation of the task scheduling system can be effectively guaranteed in the process.

One or more embodiments of the present application may further include: the to-be-processed tasks can be a user-defined and woven set of the to-be-processed tasks, and the set of the to-be-processed tasks comprises at least one task type of the to-be-processed tasks.

Illustratively, the to-be-processed tasks may be a custom set of to-be-processed tasks that are woven into the execution by the user through the serial peripheral interface, and may include at least one task type of the to-be-processed tasks, for example, hypertext Transfer Protocol (HTTP) tasks, script tasks, and the like.

In summary, in the embodiment, combined execution of multiple task types is supported, custom expansion of tasks is supported, and the universality and flexibility of the task scheduling method can be improved.
