Wherein, each virtual unit can a corresponding process.
S120, described process is assigned in corresponding virtual machine according to pre-defined rule;
Wherein, virtual machine (VirtualMachine) refer to by software simulation have complete hardware system function, the complete computer operated in a completely isolated environment.The operable KVM of the present invention (Kernel-basedVirtualMachine) virtual machine needs hardware supports, is hardware based Full-virtualization.
Virtual machine technique is the one of Intel Virtualization Technology, things is become another kind of form from a kind of formal transformation by so-called Intel Virtualization Technology exactly, the most frequently used Intel Virtualization Technology has the virtual of internal memory in operating system, the memory headroom that during actual motion, user needs may be far longer than the memory size of physical machine, utilize the Intel Virtualization Technology of internal memory, user can turn to internal memory by virtual for a part of hard disk, and this is transparent to user.
Virtual machine monitor (VirtualMachineMonitor, VMM) is the core of virtual machine technique, and it is the code of one deck between operating system and computer hardware, is used for hardware platform to be divided into multiple virtual machine.VMM operates in privileged mode, Main Function is isolation and manages the multiple virtual machines run on upper strata, arbitrates their access to bottom hardware, and (comprises processor for the virtual a set of virtual hardware environment independent of actual hardware of each client operating system, internal memory, I/O equipment).VMM adopts certain dispatching algorithm sharing CPU between each virtual machine.
Use virtual machine can make to have multiple virtual machine in a multi-core computer, save hardware resource, saving resource while guarantee test effect.
Wherein, a variety of forms of distribution can be had here, as long as can realize utilizing multiple stage virtual machine to carry out the operation of process; Can be such as the quantity first determining virtual machine here, all processes are evenly distributed in each virtual machine; Also can be preferred, first determine the best number of processes of virtual machine; Again according to quantity and the described best number of processes of described process, determine the quantity of virtual machine, and be the process that each described virtual machine distributes best number of processes.Namely first can obtain virtual machine by methods such as tests and not only can have good speed but also test rate can be improved when the several process of operation, namely the best number of processes of virtual machine is obtained, again according to testing the number of processes obtained at every turn, determine the virtual machine quantity required for this test, make every virtual machine distribute the process of best number of processes.Make to test each virtual machine at every turn and be in optimum state, the speed of snowslide test can be improved.
S130, control described virtual machine parallel running process, wherein, described virtual machine utilizes Time Slice Circular Scheduling to run process.
Wherein, Time Slice Circular Scheduling is that in CPU, one is the most ancient, the most simply, the most fair and use the widest algorithm, dispatches also known as RR.Each process is assigned with a time period, is called its timeslice, and namely this process allows the time of operation.
If process is also in operation at the end of timeslice, then CPU will be deprived of and distribute to another process.If process is blocked or terminated before timeslice terminates, then CPU switches at once.What scheduler program will do is exactly maintenance ready process list, and after process is finished its timeslice, it is moved to the end of queue.The present invention utilizes Time Slice Circular Scheduling to control the time of test process, makes the operation of process meet the demand of snowslide test.Illustrate benefit of the present invention below.
Such as, snowslide test request multiserver analogue system configures 300 virtual units, each Equipments Setting 4 point data, totally 1200 point data, require during test that the data completing snowslide test in 100ms send, and in background system, receive the message of 1200 point data.Actual test shows, the time that background system receives snowslide data is directly proportional to the transmitting time of snowslide data, and the time bottleneck tested of snowslide is in the transmission phase of snowslide data.In order to reach above-mentioned performance index, the present invention is in multiserver analogue system, based on the round-robin law theory of CPU, adopt VMM virtual machine technique, the high speed avalanche method of testing of a kind of multi-service oriented device emulation is proposed, namely in multiserver analogue system, virtual machine technique is added, 300 virtual units are evenly distributed to (number of virtual machine is generally not more than the check figure of CPU) in multiple virtual machine, each virtual machine independent operating in a core of CPU, by CPU oneself management and running.
The each virtual cpu of virtual machine only operates on a physical core, and therefore the speed of service of the higher virtual machine of cpu frequency is also higher, and virtual cpu quantity contributes to the performance promoting application more.5 virtual cpus are employed in the snowslide test model of this analogue system, respectively 300 processes are divided equally and run on 5 CPU, each CPU only needs operation 60 processes, then uses virtual machine technique to make 5 CPU parallel runnings, finally reaches the object shortening running time.
In analogue system of the present invention, each process runs required time much smaller than 1ms, but minimum at the time granularity of process switching is 1ms, 300 process polls needs 300ms, and this system needs 100ms just 300 processes to be finished, therefore need, based on common time sheet round robin algorithm, to make corresponding optimization, thus improve cpu busy percentage.Concrete optimization comprises employing Multi-core concurrent fashion, improves cpu busy percentage.
When using common multi-process mode to realize, in the process that CPU inside performs, remain serial and perform each process, its time used to be taken time sum by 300 process run time and other process schedulings of CPU, and computational methods are as follows:
Wherein, T is total time, and N=300, k are the time coefficient that each process is run, t
ibe that the i-th process runs the time used, D is that CPU works as other program schedulers time used in pronucleus.
In this analogue system, each process runs required time much smaller than 1ms, but minimum at the time granularity of process switching be 1ms, 300 process polls needs 300ms, its execution sequential chart as shown in Figure 2;
Because CPU is when scheduling pronucleus existing other processes, 300 process serial process times used are much larger than 300ms.Common multi-process mode can not meet the requirement of snowslide test, needs to adopt new test model.
The present invention adopts multinuclear multi-process mode can realize concurrent process on multiple CPU core, thus etc. pending process divide equally and run at each CPU.
Running time, account form was as follows:
Wherein, T
mthe time (m=1 that m virtual machine sends snowslide data ... 5), N=60, k are the time coefficient that each process is run, t
ibe that the i-th process runs the time used, D is other program schedulers time used in m core.Then, total time is tested in snowslide is the total time being maximum time that 5 virtual machine snowslide data send snowslide test.Each process that the present invention carries out after the optimization of multinuclear multi-course concurrency formula performs sequential chart as shown in Figure 3.Can find out from the graph, after multi-process algorithm carries out multi-core parallel concurrent optimization, execute on 300 process theories and only need 60ms.
The method employing virtual machine technique and CPU time sheet take turns the mode that robin combines; can realize within a few tens of milliseconds; success sends 300 table apparatus, 1200 report services analogue datas; both solved the problem that actual needs disposes a large amount of protection supervisory equipment, the difficult problem that analogue system simulates single device, snowslide test is difficult to Synchronization Control can have been solved again.Practical application effect shows, the high speed avalanche test model of multi-service oriented device emulation can emulate and all types of device simulation by correct completion system, has time of building, the speed optimizing snowslide concurrent test, the flexible operation of shortening snowslide test environment, arranges convenience, stable and reliable operation, multiple functional and testing efficiency high.
