Measuring parameter corresponding first and borrowing parameter is yes/no.When the corresponding first borrow parameter of the first semaphore parameter is to be,
Illustrate that above-mentioned subject thread pond allows to borrow the license of other thread pools, then the available above-mentioned subject thread pond of terminal wait borrow
Use licensed number.When detecting that the task quantity is less than or equal to the targets threshold, then terminal can be without any processing, etc.
Whether the task quantity in license waiting list to detect above-mentioned subject thread pond next time is greater than the preset targets threshold.
When it is no that the first semaphore parameter corresponding first, which borrows parameter, illustrate that above-mentioned subject thread pond does not allow to borrow other lines
The license of Cheng Chi calls the target when then terminal can wait the quantity of license indicated by the first semaphore parameter to be greater than 0
Idle thread indicated by license in thread pool handles the task in above-mentioned license waiting list.One idle thread can be located
Manage a task.Wherein, targets threshold can be the maximum waiting task quantity of the preset thread pool of terminal, such as targets threshold
It is 20.Licensed number to be borrowed can be preset for terminal, if the licensed number to be borrowed in subject thread pond is 10.Terminal
In the licensed number to be borrowed of each thread pool can be identical, can not also be identical, if terminal is that thread pool A1 is preset wait borrow
It is 10 with licensed number, be the preset licensed number to be borrowed of thread pool A3 is 15 etc..
In some possible embodiments, terminal detect above-mentioned task quantity be greater than preset targets threshold and on
Stating the corresponding first borrow parameter of the first semaphore parameter is when being, when can count the processing of each task in a period of time
It is long, and the average treatment duration of task in this time can be calculated.Terminal available preset task maximum waiting time,

Task quantity, which can be determined as the licensed number to be borrowed in above-mentioned subject thread pond by terminal.For example, it is assumed that one
The section time is in 1 hour before current time.In 1 hour before terminal statistics current time when the processing of each task
It is long and 2 minutes a length of when the average treatment of task in 1 hour before calculating current time.Assuming that preset task maximum etc.
When it is 30 minutes a length of, permit waiting list in task quantity be 20.Terminal calculating task quantity 20 and average treatment
Product between duration 2 minutes 20*2=40 minutes, by the product 40 minutes between 30 minutes task maximum waiting times
Difference (40-30=10 minutes) divided by average treatment duration 2 minutes resulting quotient (10/2=5) into the value (5 after one
It is a) it is determined as the licensed number to be borrowed in subject thread pond, i.e., 5.
S103 obtains semaphore parameter group belonging to the first semaphore parameter, and believes from N number of the second of semaphore parameter group
Number amount parameter in determine M third semaphore parameter.
In some possible embodiments, terminal can obtain above-mentioned first signal from preset semaphore database
Semaphore parameter group belonging to parameter is measured, may include the first semaphore parameter and N number of second in the semaphore parameter group
Semaphore parameter.Terminal can detecte each second signal amount parameter pair in N number of second signal parameter of the semaphore parameter group
It is yes/no that second answered, which borrows parameter, and it is yes for can borrowing parameter in N number of second signal amount parameter corresponding second
Second signal amount parameter be determined as third semaphore parameter, obtain M third semaphore parameter.Second borrow parameter can be used
Whether the license in this thread pool of instruction allows to be borrowed by other thread pools.M can be less than or equal to N, M and N all can be
Integer more than or equal to 1.
For example, it is assumed that the first semaphore parameter is SA1, semaphore parameter group belonging to the first semaphore parameter is SPS_A,
It include this 2 second signal amount parameters of SA2, SA3 in semaphore parameter group SPS_A.Terminal detects second signal amount parameter respectively
The corresponding second borrow parameter of SA2 is yes/no, the corresponding second borrow parameter of SA3 is yes/no.Since second signal amount is joined
Number SA2 it is corresponding second borrow parameter be it is yes, then SA2 is determined as a third semaphore parameter；Second signal amount parameter SA3
Corresponding second borrow parameter be also it is yes, SA3 is determined as another third semaphore parameter, obtains 2 third semaphores ginseng
Number.
S104 borrows licensed number to be borrowed to the matched M thread pool request of M third semaphore parameter, and adjusts
Appointing in the license waiting list of the idle thread processing target thread pool indicated by the license borrowed in M thread pool
Business.
In some possible embodiments, terminal is after determining M third semaphore parameter, can be from preset
Each matched thread of third semaphore parameter with above-mentioned M third semaphore parameter is obtained in semaphore database respectively
Pond obtains M thread pool.One of semaphore parameter can be matched with a thread pool.For appointing in the M thread pool
One thread pool i, when being greater than zero with the quantity of license indicated by the matched third semaphore parameter of thread pool i, terminal can
To borrow one or more licenses to thread pool i.When with license indicated by the matched third semaphore parameter of thread pool i
Quantity when being equal to zero, terminal can the thread pool in addition to thread pool i into the M thread pool borrow one or more
License.Terminal can detecte the quantity of the license borrowed after any one thread pool into the M thread pool borrows license
Whether above-mentioned licensed number to be borrowed is equal to.When detect borrow to license quantity be equal to should when borrowing licensed number,
Then terminal can stop other thread pools into the M thread pool and (herein refer to the thread not being borrowed in M thread pool
Pond) license is borrowed, and idle thread indicated by the license borrowed from the M thread pool can be called to handle above-mentioned target
Task in the license waiting list of thread pool.One idle thread can handle a task.When detecting that borrow arrived permitted
Can quantity be less than should when borrowing licensed number, then terminal can be removed into the M thread pool thread pool that was borrowed it
Outer any thread pool borrows one or more licenses, until the quantity of the license borrowed be equal to be somebody's turn to do licensed number to be borrowed or
When the M thread pool, which all borrows, to be finished, stop borrowing license.Task of the embodiment of the present application in license waiting list
When quantity is excessive, to the license for allowing other thread pools borrowed to borrow the license of licensed number to be borrowed, and borrow is called to arrive
Task in indicated idle thread processing license waiting list, can be effectively relieved the caching pressure of license waiting list,
And the waiting time of task can be reduced, improve the treatment effeciency of task.
For example, it is assumed that third semaphore parameter includes SA2, SA3, M=2 at this time.Assuming that licensed number to be borrowed is 5.Eventually
End obtains and the matched thread pool A2 of third semaphore parameter SA2 and third semaphore parameter respectively from semaphore database
The matched thread pool A3 of SA3.Terminal obtains the quantity (i.e. the value of SA2) of license indicated by third semaphore parameter SA2, it is assumed that
The quantity of license indicated by third semaphore parameter SA2 is 3.The number of the license as indicated by third semaphore parameter SA2
Amount 3 is greater than 0, and the difference 5 between the quantity 0 of total licensed number to be borrowed 5 and the license currently borrowed is signified greater than SA2
The quantity 3 for the license shown, terminal borrow the quantity license of license indicated by SA2 to thread pool A2, that is, borrow 3 licenses.
Terminal detect borrow to licensed number 3 be less than licensed number 5 to be borrowed, obtain third semaphore parameter SA3 indicated by
The quantity (i.e. the value of SA3) of license, it is assumed that the quantity of license indicated by third semaphore parameter SA3 is 4.Due to third signal
The quantity 4 for measuring license indicated by parameter SA3 is greater than 0, obtains total licensed number to be borrowed 5 and the current license borrowed
Difference 5-3=2 between quantity 3.Since this difference 2 is less than 4, then the difference license is borrowed to thread pool A3, that is, borrow 2
A license.Terminal detect at this time borrow to licensed number 3+2=5 be equal to licensed number 5 to be borrowed, then stop borrow permitted
Can, and borrow from thread pool A2 3 licenses are dispatched to any 3 tasks in license waiting list, in order to call
Idle thread in thread pool A2 handles this 3 tasks；Borrow from thread pool A3 2 licenses are dispatched to license and wait team
Any 2 tasks in column, in order to call the idle thread in thread pool A3 to handle this 2 tasks.Wherein, a task point
Send a license.
