Example is applied in order to describe to facilitate, runs an application program on a virtual machine, but an application program can run on it is multiple
On virtual machine.Virtual machine is assigned to this relationship of application program, and the embodiment of the present invention can be denoted as.So having：
So thatSet up
Based on above description, the embodiment of the present invention is specifically described below.
The embodiment of the present invention provides a kind of resource scheduling system, and with reference to system architecture as shown in Figure 1, which includes pipe
Node and physical node are managed, wherein：
Management node, each application program pair when reaching the target of scheduling strategy for being obtained according to the scheduling strategy of user
The resource collection answered, resource collection include the stock number that each virtual machine occupies when any application program is run on virtual machine,
And resource collection is sent to each physical node；
Physical node, the least resource amount for determining each virtual machine distribution on physical node according to resource collection, then
The surplus yield of physical node after distribution least resource amount is proportionately distributed to each virtual machine on physical node；
Physical node is additionally operable to the total resources that each virtual machine after distribution on physical node obtains being sent to management
Node；
Management node is additionally operable to according on the corresponding total resources of each virtual machine and physical node on physical node
The current resource usage amount of each virtual machine obtains the resource utilization of physical node, and then each according to resource utilization scheduling
The resource load of physical node.
Specifically, in application-level scheduling technology, management node is reaching scheduling according to the acquisition of the scheduling strategy of user
It can be specifically used for when the corresponding resource collection of each application program when the target of strategy：According to the effectiveness of the scheduling strategy of user
Function acquisition reaches the corresponding resource collection of each application program when the target of scheduling strategy.
Wherein, which may include：
f_app(appk) indicate the target of scheduling strategy, target be user buy resources of virtual machine expense it is minimum or empty
The time that quasi- machine completes task is most short, costtT-th of virtual machine VM of k-th of application program is distributed in expressiontUnit resource
Price in unit interval, RtIndicate the stock number that t-th of virtual machine for distributing to k-th of application program occupies, f_time (Rt,
missiont) indicate that t-th of virtual machine completes distributed task amount missiontWhen occupied time.
This is because, in the application of cloud computing, user needs to buy certain resources of virtual machine by paying, therefore,
In order to complete the operation submitted, user needs to weigh between resource and expense.The virtual machine of user's application is more, then resource is got over
More, the time to fulfil assignment is shorter, and certainly total expense can also improve namely how resource is chosen, and depends on the scheduling of user
Strategy.
For example, when user wishes least cost, the target of scheduling strategy can be expressed as：For each VMt, determine
Go out RtSo that f_app (appk,Rt‘)=min (f_app (appk,Rt))。
If the user desired that the time of the task of completion is most short, the target of scheduling strategy can be expressed as：For each
VMt, determine RtSo that：
min(f_time(Rt',minssiont'))=min (min (f_time (Rt,minssiont)))
Certainly, no matter the scheduling strategy of user's final choice is which kind of target be based on, it can remember that user is appkSelection
Resource collectionFor：Wherein, skIt is expressed as appkDetermining skA virtual machine,It indicates
Distribute to the s of k-th of application programkThe stock number that a virtual machine occupies.Namely resource collection includes any application program fortune
The row stock number that each virtual machine occupies when on virtual machine.
Here resource can be understood as distributing to the cpu resource of virtual machine, memory, network bandwidth and disk size etc..
After application layer is completed to the resource allocation of application program, management node needs to determine for each application program
Resource collection is sent to each physical node, in order to which physical node determines each virtual machine according to the resource collection received
Total resources, namely carry out the scheduling of resource of virtualization layer.
First, physical node can be determined first according to resource collection on physical node after receiving resource collection
The least resource amount of each virtual machine distribution, then in proportion by the surplus yield of the physical node after distribution least resource amount
Distribute to each virtual machine on the physical node.
Specifically, physical node can be run on according to any application program in the corresponding resource collection of each application program
The stock number that each virtual machine occupies when on virtual machine determines the minimum that each virtual machine belonged on the physical node should distribute
Stock number, the least resource amount that any virtual machine on the physical node occupies are that any virtual machine is right in each application program
The sum of stock number answered.That is, first to ensure the stock number of required virtual machine when each application program operation.
Illustratively, since the stock number on physical node is certain, it is believed that physical node is before distributing resource
Initial surplus yield R_resnodei=Rnodei,1<=j<=ni, j-th of virtual machine point on i-th of physical node
The stock number being fitted onThen since j=1, for the stock number that the distribution of each virtual machine is minimum.That is, willIt is set toWherein：
And Indicate appkIn the jth of i-th of physical node
The stock number being assigned on a virtual machine, while updating surplus yield R_resnodeiFor：
Until j=ni。
After being assigned with least resource amount for each virtual machine on physical node, physical node can obtain its residue
Stock number, the surplus yield are just that the total resources of physical node subtracts as each virtual machine determination on physical node most
Small stock number.
Then, each virtual machine that surplus yield can be proportionately distributed on physical node, on physical node
The surplus yield that any virtual machine is assigned to is that the least resource amount of any virtual machine accounts for the allocated stock number of physical node
Ratio and surplus yield product, allocated stock number be physical node on each virtual machine least resource amount it
With.
Specifically, since the least resource amount that the virtual machine on physical node is assigned to may differ, surplus resources
Amount can account for the ratio of allocated stock number to distribute to each virtual machine according to the least resource amount of virtual machine, that is, empty
Least resource amount that quasi- machine obtains it is more can continue to distribute more surplus yields, the least resource that virtual machine obtains
That measures less some can continue the few surplus yield of some of distribution, to ensure resources of virtual machine abundance.It specifically can be according to such as
Lower method distribution surplus yield R_resnodei：
For example, there are 10 cpu resources on physical node, and operation there are 2 virtual machines on the physical node, first
The least resource amount that virtual machine needs is 5 cpu resources, and the least resource amount that second virtual machine needs is 3 cpu resources,
After distributing least resource amount for each virtual machine, remaining 2 cpu resources can be first void according to the algorithm of 5/8*2
Quasi- machine continues to distribute surplus yield, continues distribution surplus yield according to the algorithm of 3/8*2 for second virtual machine, then the
The total resources that one virtual machine obtains is 5/8*2+5, and the total resources that second virtual machine obtains is 3/8*2+3.
Physical node for each virtual machine after distributing stock number, total money that physical node can obtain each virtual machine
Source amount is sent to management node, in order to which management node is scheduled physical layer according to resources of virtual machine.It specifically can basis
The corresponding total resources of each virtual machine on the physical node resource usage amount current with each virtual machine on physical node
The resource utilization of physical node is obtained, and then dispatches the resource load of each physical node according to resource utilization.
It specifically, can be according to formulaThe resource utilization of physical node is obtained,Table
Show the resource utilization of i-th of physical node,Indicate the corresponding total resources of j-th of virtual machine on i-th of physical node
Amount,Indicate the corresponding total resources of i-th of physical node,Indicate j-th of virtual machine on i-th of physical node
Current resource usage amount.
Then scheduling of resource can be carried out according to the target of physical layer scheduling, if management node needs balanced each physics section
The load of point, then when obtaining the variance minimum of the resource utilization of each physical node, the virtual machine money on each physical node
Source distribution, i.e., when the target of physical layer scheduling scheme is load balancing, utility function can be：
Map M (S_VM, S_Node) so that [Lnodei-E(Lnodei)]2It is minimum；
When the resource utilization of a certain physical node is relatively low, show the idling-resource of virtual machine on the physical node compared with
It is more, it at this time can be by the virtual machine (vm) migration on other nodes to this node；When the resource utilization of a certain physical node is higher,
Show that the idling-resource of virtual machine on the physical node is less, it at this time can be by the virtual machine (vm) migration on this node to other nodes
On, to reach the load balancing of each node.
If management node need reduce physical node number, can first according to the total resources of each physical node from
Small sequence is arrived greatly to arrange each physical node, then successively distributes virtual machine to physical node, until current
The total resources of the physical node of distribution, which has been assigned, is again allocated next physical node, then determines will be all virtual
After machine is respectively assigned on physical node, if there are the physical nodes of unallocated virtual machine, and if it exists, then closes unallocated void
The physical node of quasi- machine so can need to distribute virtual machine to physical node as few as possible, be in reducing
The physical node quantity of open state, reduces the energy consumption of physical node.
By the explanation of above-mentioned 3 levels, namely if to realize the resource dispatching strategy in virtualization system, Ke Yiyou
The scheduling scheme for first considering application layer, on the basis of ensureing the resource requirement of user, infrastructure providers are just from virtualization
Layer, physical layer angle the configuration status of resource is adjusted.Namely during entire scheduling, priority is：Using
Layer ＞ virtualization layer ＞ physical layers, can make scheduling system consider cloud computing user and infrastructure resources provide and
The interests of both sides, more reasonably distribute resource from the overall situation.
The embodiment of the present invention provides a kind of resource scheduling system, which includes management node and physical node, management knot
The point corresponding resource collection of each application program, resource set when reaching the target of scheduling strategy according to the acquisition of the scheduling strategy of user
