As shown in Figure 1, computational resource allocation method of the present invention comprises the following steps:
Step 1, according to every computational resource of task requests being assessed because of prime implicant of assessment, assessment because prime implicant comprises computational resource factor (such as the resource factors such as CPU, internal memory) and limiting factor, judge assessment whether effective, if assess effectively; perform step two; If it is invalid to assess, perform step four; Limiting factor comprises parameter limit (for example: the maximum virtual machine number of server), Warrant Bounds (as the user of request task to certain server without operating right, can not use the resource of this server) etc.;
Step 2, if assessment effectively, by preassignment strategy preassignment computational resource;
Step 3, actual allocated computational resource, adds successful preassignment computational resource mapping task resource plan and executes the task; Such as, if when batch operation, allow part virtual machine to be allocated successfully;
Step 4, if assess invalidly, provides assessment feedback, and the task of computational resource request is belonged to computing pool.
Wherein, preassignment strategy is assignable strategy for each server-assignment computational resource, as: acquiescence is used balanced allocation strategy, and (weight of each server is attempted Resources allocation number of times in it and is inversely proportional to, be that number of attempt is more, its authority is lower), if known first server A, second server B and hypothesis two-server can meet the computational resource request of two virtual machines, existing two virtual machine request computational resources, the upper required computational resource of virtual machine of each preassignment of first server A, second server B.
As shown in Figure 2, described step 1 comprises the following steps: step 11, and according to the authority of operation user to each server, that obtains available server can distributes calculation resources amount; Step 12, according to assessing because of prime implicant of the assessment of each computational resource of user's acquisition request, judges whether assessment is effective, if effectively, performs step two; If invalid, perform step four.Wherein, step 11 specifically comprises the following steps: under cluster, register physical host as each server and add in the computing pool under cluster; Every system parameters of configuration server, comprises resource virtualizing parameter, resource limitation parameter; The computational resource of holding by virtual parameter conversion physical host becomes virtual resources, and is stored in the resource statistics table of computing pool, in resource statistics diagram, represents; Safety officer is active user's distribution object authority, the authority of the resources such as the operable server of restriction active user; The self-defined task configuration of active user (such as, virtual machine preparation), and send task requests (such as creating virtual machine request) to task scheduling management platform; Task scheduling management platform is processed this task requests, obtains real-time computational resource allocation situation from resource statistics table, as the foundation of computational resource assessment; From user request, extract the minimum request amount of computational resource, and obtain available server by user right can distributes calculation resources amount, simultaneously in conjunction with image parameter restriction initialization assessment because of prime implicant.Step 12 is assessing because of prime implicant according to the assessment such as minimum request amount and image parameter restriction of each computational resource of user's acquisition request specifically.For example, create virtual machine assessment comprise the maximum virtual machine parameter limit of CPU, server presence, server because of prime implicant.

As shown in Figure 4, described step 3 comprises the following steps: step 3 11, according to the calculated preassignment computational resource of task resource mapping execute the task (such as, task scheduling management platform sends physics according to the task resource plan after computational resource preassignment success to each destination server and creates virtual machine task requests), judge whether task runs succeeded; Step 3 12, if tasks carrying success, and the actual computational resource that takies, i.e. actual allocated computational resource, upgrades pre-allocation resource table respective resources by freezing to actual taking; Step 3 13, if tasks carrying failure is carried out rollback and is discharged preallocated computational resource (giving back preallocated computational resource).
As shown in Figure 5, described step 4 comprises the following steps: step 4 11, if computational resource assessment is invalid, and the information of the entity (virtual machine) of feedback computational resource bottleneck or unsuccessful distributes calculation resources; Step 4 12, goes to the request of the preassignment computational resource that fails under computing pool, under computing pool, carry out request task (such as, under computing pool, create virtual machine instance), judge whether success of request task; Step 4 13, if request task success (such as, virtual machine instance creates successfully), vacant resource; Step 4 14, if rollback is carried out in request task failure (such as virtual machine instance creates unsuccessfully).Wherein, when virtual machine instance is closed condition, starts if need and need to select the enough servers of computational resource as host.For example, successively each assessment to virtual machine because of prime implicant inspection, ungratifiedly assess invalidly if having, provide feedback.As: if CPU lazy weight, feedback resources bottleneck is CPU quantity, and shows respectively request resource quantity and actual assignable number of resources.Virtual machine is directly created under computing pool simultaneously, when waiting for server resource is enough, then selects server to take computational resource.
The present invention has following feature:
One, utilize cluster resource statistical to obtain real-time cluster computational resource service condition, before resource is distributed, produce the use distribution situation of the computational resource of current cluster, thereby accurately cluster is carried out to the distribution of computational resource.
Two, in computational resource allocation, first the every resource to task requests is assessed, assessment because prime implicant is except computational resource factor (CPU, internal memory), also comprise some limiting factors, such as parameter limit (for example: the maximum virtual machine number of server), Warrant Bounds (as the user of request task to certain server without operating right, can not use the resource of this server) etc., these estimation items can be expanded as required, before computational resource preassignment, current cluster resource is carried out to Efficient Evaluation with regard to guaranteeing like this, exposure resource bottleneck as early as possible.
Three, if after computational resource assessment effectively, computational resource allocation method is according to tactful Resources allocation and produce task resource plan, task resource comprises the resource of each destination server and the task that is pre-assigned in the works, preallocated computational resource only can this task take before this task finishes, thereby had stopped resource and be assigned to the hidden danger of the tasks carrying failure that actual time difference taking causes.
Four, if after computational resource assessment was lost efficacy, be that Servers-all under computing pool carries out preassignment without enough resources, now the resource request of this task is dispensed under computing pool, the continuation that does not affect task is carried out, the virtual machine instance that this task produces belongs to computing pool, actual and vacant computational resource.Hold this virtual machine when the server under computing pool has enough resources, and need to this virtual machine take computational resource (as started virtual machine), select the server of available resources to be used as host and move virtual machine.If under server, some virtual machine is shut down simultaneously, now these virtual machines can be moved out to computing pool from server, discharge its actual computational resource taking, just so realized computational resource allocation as required.
Above specific embodiments of the invention are described.It will be appreciated that, the present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
