Embodiment
The intelligence resource management method of a kind of wireless ultra-wideband cluster computer provided by the present invention is based on the cluster computer of being made up of the connection of wireless ultra-wideband signal between main frame group and the terminal group.Below in conjunction with specific embodiment the specific embodiment of the present invention is described.
The wireless ultra-wideband cluster computer of embodiment as shown in Figure 6, the main frame group is made up of three main frame M1, M2, M3 and station terminal start watch-dog T-Monitor, these four equipment are interconnected by local area network (LAN); Terminal group is made up of 6 station terminal T1, T2, T3, T4, T5, T6; Interconnected between main frame group and the terminal group by the wireless ultra-wideband signal; An average main frame can provide service for two station terminals in the resource distribution.
One, main frame Auto Power On
The initial condition of cluster computer is that 3 main frames and 6 station terminals all are in off-mode in the present embodiment, has only " starting up of terminal watch-dog " T-Monitor to be in state of activation, and whether monitoring in real time has starting up of terminal.
Suppose that existing 3 users start shooting on 3 station terminal T1, T2, T3, each user need take 50% of a host resource.T-Monitor has monitored main frame start, triggers a main frame start (present embodiment select condition be defined as the sequence number minimum) according to the Information Selection of the relevant main frame of its storage, promptly at first selects to trigger the M1 start.If M1 can't start shooting in time T (T can be taken as 1 minute or At All Other Times), T-Monitor will trigger the M2 start, analogize in proper order.This embodiment supposes that M1 can normal boot-strap.After M1 successfully started shooting, the state of T-Monitor just was changed to unactivated state.
M1 receives the user's logon information that sends over from T1, T2, T3 three station terminals, and after authenticating, beginning provides service for the user.But M1 finds the resource of a main frame and can not satisfy three users' resource request, starts shooting so M1 triggers main frame M2, and M1 provides service for the user of T1, T2, and M2 provides service for the user of T3.If T4 start at this moment, M2 just provides service for T3, T4; If T5 start, the main frame group will trigger the M3 start and provide service for T5; If the T6 start, M3 will provide service for T5, T6.
Two, user's classification
Present embodiment is divided into Three Estate with the user: 0 grade is domestic consumer, can take the resource of a main frame 30%; 1 grade is the user that certain operand is arranged, and can take the resource of a main frame 60%; 2 grades is the users that need carry out a large amount of computings, can take the resource of a main frame 100%.
The user needs the application user class when account number is landed in cluster computer manager application.Hypothesis user 1 application is 0 grade of user in the present embodiment, lands at T1; User's 2 applications are 1 grade of user, land at T2; User's 3 applications are 2 grades of users, land at T3.
T-Monitor has monitored starting up of terminal, to trigger main frame M1 start, but user 1 and user 2 need take the resource of a main frame 90%, therefore the resource of M1 can not satisfy three users' demand, so M1 triggers the M2 start, M1 just provides service for user 1 and user 2 like this, and M2 provides service for user 3.
Three, dynamic resource scheduling
Establishing cluster computer in the present embodiment is being three user's services: user 1 is 0 grade of user, lands at T1; User 2 is 1 grade of user, lands at T2; User 3 is 2 grades of users, lands at T3.M1 provides service for T1, T2, and M2 provides service for T3, and M3 is start not.
The main frame group monitors the situation that each user uses resource, and preserves the scheduling situation of one " dynamic resource scheduling tabulation " record resource, and present embodiment is got threshold values L1=50%, threshold values L2=90%.
If user 2 is carried out be operated in only used in the time T (T can get 30 minutes or At All Other Times) institute's Resources allocation 40% (＜L1), and user 3 in time T, used institute's Resources allocation 95% (＞L2).So, the main frame group with user's 2 shared resources adjust a part (present embodiment is 50%) promptly a host resource 30% (60% * 50%=30%) as reserved resource.And with the part of reserved resource (present embodiment gets 50%, be a host resource 15%) distribute to user 3 and use, and the concurrent operation function that starts between main frame is accelerated arithmetic speed.In " dynamic resource scheduling tabulation ", the dynamic resource scheduling tabulation is as shown in table 1 in the present embodiment with the scheduling of resource outcome record for the main frame group.
Table 1
| User's name | Rank | Answer Resources allocation | The actual allocated resource | Adjust to reserved resource | Take reserved resource |
| The user 1 | 0 | 30％ | 30％ | 0 | 0 |
| The user 2 | 1 | 60％ | 30％ | 30％ | 0 |
| The user 3 | 2 | 100％ | 115％ | 0 | 15％ |
| ...... |
Annotate: present embodiment is weighed the size of resource with the percentage that takies a host resource
If user's 2 resource needed by a host resource 24% (60% * 40%=24%) rises to 34%, whether main frame cluster inquiry reserved resource earlier can meet the demands, now remaining reserved resource is 15% of a host resource, can satisfy its requirement, so the main frame group distributes to user 2 with the reserved resource of a host resource 10%.If user's 2 resource needed continue to rise to 60% by 34% of a host resource, obviously reserved resource is not enough, all reclaims so the main frame group just will distribute to user 3 reserved resource, redistributes to user 2.
Need to prove, be the size of recently weighing resource with the percentage that takies a host resource in the present embodiment, can adopt other quantized value to weigh the size of resource in the practical application.
Four, main frame shuts down automatically
Suppose that cluster computer provides service for 6 users, the resource of distributing to each user is 50% of a host resource, and M1 provides service for T1, T2, and M2 provides service for T3, T4, M3 provides service for T5, T6, and the main frame group monitors the resource operating position of each terminal in real time.
If the user of T4 and T6 finishes the work to withdraw from land, after the main frame group monitors this situation, just will provide the T5 of service to switch to by M2 by M3 and provide service for T5, the M3 free time after handoff procedure is finished be so M3 shuts down automatically.
If the user of T2 and T3 also withdraws from land, the main frame group just will provide the T5 of service to switch to by M1 by M2 and provide service for T5, and M2 was promptly idle after handoff procedure was finished, so M2 is shutdown automatically also.
If T1 and T5 also withdraw from succession land, M1 is also idle like this, so M1 shuts down automatically.Because all main frames all cut out, so the state of " starting up of terminal watch-dog " T-Monitor is changed to state of activation.
Above embodiment and described description of contents the embodiment of intelligence resource management method of a kind of wireless ultra-wideband cluster computer provided by the present invention, be not to be used for limiting practical range of the present invention.
