Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 1, fig. 1 is a flowchart of an embodiment of a method for controlling a task server according to the present invention, including:
step S101: and when receiving the trigger instruction, the central control server acquires server information stored in the local, wherein the server information comprises the current state of the task server and the time required by the task server to execute the task.
And the central control server is used for controlling the task server. The triggering instruction is used for triggering the central control server to implement control, and includes: and when a new task, a task with waiting, or server information updated by a task server is received, the system is considered to receive a trigger instruction.
The central control server locally stores server information of the task servers, the server information is sent to the central control server by each task server, and the server information comprises the current state of the task servers and the time required by the task servers to execute the tasks. The current state of the server includes whether the task server is in an idle state or a task execution state. The time required by the task server to execute the task can be obtained by recording the starting time and the ending time when the task server executes the task.
Step S102: and judging whether a task server with the current state being an idle state exists according to the server information.
According to the current state of the task server in the server information, whether the current state of the task server is an idle state or a non-idle state (namely a task execution state) can be judged, so that whether the task server with the current state of the task server being the idle state exists or not is determined.
Step S103: and if so, determining that the time required for executing the task belongs to the task servers within the first preset time range in the task servers in the idle state, and defining the time as a first set.
The first predetermined time is a time that is acceptable to the user and is required for the task server to perform the task. Generally, the shorter the time required for executing the task, the better, and therefore, the first predetermined time may be predetermined according to the actual application. According to the time required by each task server to execute the task, the fact that the time required by the task execution belongs to the task servers within the first preset time range can be determined, and the time is defined as a first set. Further, a task server that requires the shortest time to execute a task may be selected.
Step S103 is specifically configured to determine, in the task servers in the idle state, that the time required for executing the task belongs to the task servers within the first predetermined time range through the heterogeneous distributed load balancing algorithm, and define the time as a first set.
Heterogeneous distributed load balancing algorithms are a relatively large number of algorithms for uniform load studied in the prior art, such as: the method comprises a dynamic genetic algorithm, an HDLDF algorithm, an HDAL algorithm and the like, particularly in a heterogeneous system with busy service, the HDAL algorithm has the advantages of high resource utilization rate, better load balance and obvious scheduling speed compared with other algorithms.
The central control server mainly carries out comprehensive analysis and selection from the performance index, the task processing capacity, the current state and the current idle task server of each task server, and under the condition that comprehensive analysis factors are more, the busyness of all the task servers can be similar through a heterogeneous distributed load balancing algorithm, particularly an HDAL algorithm, and the task throughput of the whole system can be maximum.
Step S104: tasks that need to be performed are assigned to the task servers in the first set.
And selecting a task server from the first set according to the task condition needing to be executed, and distributing the task to the selected task server.
When receiving a trigger instruction, the embodiment of the invention acquires server information stored in local, wherein the server information comprises the current state of a task server and the time required by the task server to execute a task; judging whether a task server exists in which the current state of the task server is an idle state or not according to the server information; if yes, determining that the time required for executing the task belongs to the task servers within a first preset time range in the task servers in the idle state and defining the time as a first set; and distributing the tasks to be executed to the task servers in the first set. The method can automatically balance the load of the task server, thereby effectively utilizing resources and ensuring service quality.
Referring to fig. 2, when the server information further includes the performance of the task server, before step S104, the method further includes:
step S105: in the first set, a second set of task servers whose performance meets a predetermined requirement is determined. The predetermined requirement is a user acceptable performance requirement, generally speaking, the higher the performance the better.
In this case, step S104 is specifically step S104 a: tasks that need to be performed are assigned to the task servers in the second set.
The second set is a set of task servers selected from the first set, and the task servers in the second set simultaneously meet the time required for executing the task within the first preset time and the performance of the task servers meet the preset requirements. Therefore, tasks to be executed are allocated to the task servers in the second set, and resources can be more effectively used.
Other steps in fig. 2 are shown in fig. 1 and the associated text, which are not described again here.
Referring to fig. 3, after step S102, the method further includes:
step S201: and if not, determining a third set of task servers to be in an idle state within a second preset time in the task servers in the non-idle state.
Step S202: and enabling the tasks needing to be executed to enter the waiting program of the task server in the third set.
When the task server with the current state being the idle state does not exist, the task server is all executing the task and is in the non-idle state. The time required for executing a certain task is basically stable on a certain fixed task server, after the task is distributed to the task server, the time for starting the task to be executed is recorded, the time for finishing the task can be estimated according to the current time and the time required for executing the task, and after the task is executed, the task server is in an idle state. Thus, based on the estimated time for the task to end, a third set of task servers that will be idle for a second predetermined time may be determined. The second predetermined time is also determined according to the requirements of the user, for example: the task to be executed is urgent, the second preset time can select a short time, and the selected task server can finish the execution of the task within the short time and is converted into the task server in an idle state. Further, if the task also requires a task server with a specific performance, it is possible to select a task server that satisfies both the task that can be completed within the short time and the specific performance.
Referring to fig. 4, the method further includes:
step S301: and after the task server finishes the execution of the task, the current server information of the task server is sent to the central control server.
Step S302: and the central control server receives the current own server information sent by the task server and replaces the server information of the previous task server with the received server information of the task server.
After the task server completes the execution of the task, the current server information of the task server is actively sent to the central control server, so that the central control server can master the latest server information of the task server, and further, when the task to be executed exists, the overall consideration can be given to the task server, the load of the task server can be automatically balanced, and the purpose of effectively utilizing resources is achieved.
One of the implementations of the above steps S301 and S302 is as follows: after the task is distributed to the task server from the central control server, the task server is connected with the prepared script before the task is executed and quits, and the script is executed as long as the task is executed or the fault occurs. The script comprises the collected current server information and a function of sending the server information to the central control server, after the central control server receives the server information, the received server information of the task server is used for replacing the server information of the previous task server as long as the server information is updated, and further, the script can be used as a trigger instruction to trigger the central control server to judge whether a waiting task or a new task exists so as to trigger a subsequent program.
Wherein, the method also comprises: the central control server counts the time required by the task server to execute the task, obtains the average time required by the task server to execute the task, and is convenient for determining the time when the task server executing the task is to be in an idle state according to the average time required by the task server to execute the task.
The time required by the task servers to execute each specific task is basically not too same, but the difference is not too large and basically stable, and the central control server can count the average time of each task server to execute the task, so that the ending time can be estimated when the task servers are still executing the task.
