Embodiment

As shown in Figure 1, the computational resource that is used to use of the Service Management in the grid computing environment 100.Grid computing environment 100 can be distributed separately with the calculating of execution application or a distribution type computational resource of data retrieval task.Computational resource comprises

computer equipment

12,14,16,18,20 and 22.Computer equipment uses network 8 communications.Application has scalable calculation requirement.For example, using

computer equipment

12,14,16,18,20 in the

grid computing environment

100 and 22 example application is internet price configurator (configurator).Computer equipment 12 provides access to netwoks to pricing information via the web browser on the computer equipment that is connected to the internet to the user.This web browser can be can displaying contents and/or carry out any application such as the application of webpage, media file and program, such as Netscape

MicrosoftInternet

And similar application.

In this example, the webserver on the computer equipment 12 provides pricing information to the user.The calculating parameter of each price that IPC scheduler (dispatcher) 116 will calculate sends the IPC server of carrying out respectively 120,122,124 and 126 on

computer equipment

12,14,16 and 18.Because the webserver and application flexibility on the internet, user's number can change.This has just produced the dynamic calculation requirement to internet price configurator.Communication for service in IPC manager 118 and the grid computing environment 100, so that service can require and allocation and deallocation computational resource (for example, the processor in the

computer equipment

12,14,16,18,20,22) according to the fix a price dynamic calculation of configurator of internet.The allocation and deallocation computational resource makes

computer equipment

12,14,16,18,20 and 22 be designated as general-purpose computational resources by this way, and can just not be exclusively used in the peak demand of handling internet price configurator

application.IPC manager

118 and 116 collaborative works of IPC scheduler are so that IPC scheduler 116 can be visited the resource in (have access to) network 8.

The ability of the resource in this allocation and deallocation grid computing environment 100 makes IPC manager 118 can locate and use available computational resources on the basis of " as required ".In case resource is positioned, IPC manager 118 just can use the service in the grid computing environment 100 that IPC server 120,122,124 and 126 is installed on the computer equipment in the grid computing environment 100 as application.IPC scheduler 116 uses by people such as Tuecke at open grid service infrastructure (Open GridServices Infrastructure, OGSI) (WebService Definition Language, WSDL) information flow between IPC scheduler 116 and IPC server 120,122,124 and 126 is managed and exchanged to interface to the Web Service Definition Language that defines in 1.0 versions.For example, OGSI WSDL interface can be used to the calculating parameter that calculates that is used to fix a price is sent to IPC server 120,122,124 and 126 from IPC scheduler 116.The result that OGSI WSDL interface can also be used to finish sends back IPC scheduler 116 from IPC server 120,122,124 and 126.The OGSI1.0 version is incorporated herein by reference.OGSI WSDL interface makes it possible to carry out the management of (fault-resilient) controlled, that have error recovery capabilities and safety to grid computing environment 100 with such as the application of internet price configurator.

When IPC scheduler 116 uses IPC servers 120,122,124 and 126 to carry out users' calculating, the utilization of resources of service monitoring operation IPC server 120,122,124 in the grid computing environment 100 and computer equipment 126, in the grid computing environment 100.Service also utilizes this information to send to IPC manager 118.According to the comparison between utilization requirement and current resource load, IPC manager 118 can dynamically notify the service in the grid computing environment 100 so that be IPC server 120,122,124 and 126 distribution more resources, perhaps remove Resources allocation, so that make the utilization of resources in the grid computing environment 100 remain on the level of expectation.

Grid managers 152,154,156,160,162 and 164 resides in respectively in

computer equipment

12,14,16,18,20 and 22.In grid computing environment 100, grid managers is to having direction relations (directional relations), and this direction relations is categorized as a grid managers higher level (superior) of another grid managers.Grid managers can have superior relation more than one with other grid managers.For example, grid managers 152 has superior relation with grid managers 154 and 156.Grid managers can also have inferior relation (inferiorrelations) more than one with other grid managers.By these hierarchical relationships, IPC manager 118 does not need the tabulation of all computer equipments in the accesses network 8, so that use the computational resource in the grid computing environment 100.Only require IPC manager 118 can visit the network address of computer equipment (for example moving the computer equipment 12 of grid managers 152) of an operation grid managers, and this grid managers utilize it and the relation that operates in other grid managers on other computer equipment to provide dereference to other computer equipment in the grid computing environment 100 to IPC scheduler 116.

Grid managers (for example 152,154,156,160,162 and 164) safeguard with first tabulation of all superior relation of other grid managers and with second tabulation of all inferior relation of other grid managers.Each grid managers all uses for example above-mentioned OGSI WSDL interface to safeguard communication channel via " opening forever " of all grid managers of network 8 in these tabulations on transmission control protocol (TCP), HTTP(Hypertext Transport Protocol) and Simple Object Access Protocol (SOAP).These tabulations and corresponding communication channel can be modified, to allow dynamically to reconfigure trellis stage during working time.This also allows dynamically to replace the fault grid managers in level.For example, with reference to Fig. 1, if grid managers 154 breaks down, then grid managers 152 is lost it to

grid managers

160 and 162 be connected.In this case, the relation between the grid managers can be modified so that grid managers 152 has is new, with the superior relation of grid managers 160 and 162.Similarly,

grid managers

160 and 162 have new, with the inferior relation of grid managers 152.

As shown in Figure 2, designed application start and handled 200, so that before computer equipment (for example, 12,14,16,18,20 or 22) is gone up execution, obtain the essential resource of distribution in network 8 in application (for example, internet price configurator).Handling 200 also guarantees: if similar application is attempted to start simultaneously on the same asset on the computer equipment, then these two or more application can not conflict or the phase mutual interference mutually.For example, for guarantee service quality (QoS), IPC manager 118 can require: IPC server (for example 120) is unique application of carrying out on the processor in computer equipment 14.In this case, carry out if other is used on the processor of attempting simultaneously in computer equipment 14, then Another Application will be disturbed.

Handle 200 and comprise that IPC manager 118 (or some other application) sends (202) requirement to computational resource, with inquiry grid managers (for example 154) thus determine in grid computing environment 100, whether there are the available resources that require coupling with these.The information about the resource in the computer equipment has been specified in these requirements, all numbers of processor as requested, desired those processors, primary memory and network speed utilize number percent.Inquiry can also comprise that relevant this inquiry should be transmitted to which rank of the information of (in grid computing environment 100) level.Handle 200 and comprise that grid managers 154 receives (204) this requirement.

For respond from IPC manager 118, to the inquiry of available resources, handle 200 and comprise that grid managers 154 will require and resource that grid managers 154 is known is mated (206).These resources comprise the resource (for example, processor 40) in the computer equipment of directly being managed by grid managers 154 14.Current resource available and that meet the demands, that directly managed by grid managers 154 is added in the resource-query list of being safeguarded by grid managers 154.

Grid managers 154 also sends these inquiries to the grid managers 160 and 162 that has an inferior relation with grid managers 154.Handle 200 and comprise that grid managers 160 and 162 satisfies the requirement of being asked and grid managers 160 and 162 that can use and tabulations known resource (for example processor on the computer equipment 18,20) respond (208) this inquiry by sending to grid managers 154 respectively.These resource-query list of grid managers 160 and 162 known resources can also comprise by having the resource of the grid managers (not shown) management of inferior relation with grid managers 160 and 162.Grid managers 154 will add to from these resource-query list of the available resources of grid managers 160 and 162 in its resource-query list of the available resources that satisfy the requirement of being asked.Determine that there is at least one resource (for example, processor 40) in (210) in this resource-query list if handle 200, then grid managers 154 sends (214) to IPC manager 118 with this resource-query list.Otherwise, determine that (212) grid managers 154 and higher level's grid managers (for example, grid managers 152) have relation if handle 200, then grid managers 154 will send to (202) grid managers 152 to the inquiry of available resources.In response to this inquiry, grid managers 152 can not send it back unnecessary inquiry the grid managers 154 that has inferior relation with grid managers 152.

Handle 200 and comprise that the address of its corresponding grid managers in that grid managers 154 requires the tabulation of available resources and coupling, the network 8 sends (214) together.IPC manager 118 is selected resource (for example, the resource on the computer equipment 16) from this tabulation, and the resource on grid managers 154 request (216) the reservation computer equipments 16 of the resource on the Management Calculation machine equipment 16.If the resource on the computer equipment 16 still can be used for reserving (218) and reserving successfully, then grid managers 154 sends (220) reserved number to IPC manager 118.This reservation means and guarantees that IPC manager 118 has and distribute resource on the computer equipment 16 that asked, in the grid computing environment 100 to it.Grid managers 154 use the independent processing thread of carrying out to handle to come from such as the application of IPC manager 118, to the inquiry of available resources.Like this, grid managers 154 uses signal lamps (semaphore) to guarantee that identical resource (for example, processor 40) can not ask identical resource simultaneously and be assigned with a plurality of reserved number owing to different application.

If the resource in the computer equipment 16 that grid managers is determined to be asked can not be used for reserving and reserving failure, then this next one available resources are reserved in next available resources in 118 selective listings of IPC manager and request (216).If IPC manager 118 receives herd number and does not have expired (222) from sending the time-out time (timeout) that this herd number begins to measure, then the resource of IPC manager 118 in computer equipment 16 starts (224) IPC server 122 on the processor 40.By transmitting reserved number to grid managers 156 and application file begins to start IPC server 122, and grid managers 156 reads this application file so that install and carry out IPC server 122 on computer equipment 16 subsequently.

As shown in Figure 3, handling 250 computer equipments (for example 14) in grid computing environment 100 goes up to install and (for example uses, IPC server 122) so that sets up available resources for this application, use this available resources, and to remove or unload this application so that discharge described resource be that later application is used when no longer needing this resource.Handle 250 and comprise that IPC manager 118 transmits (252) and comprises the code of IPC server 122 and for how installing, customize, follow the tracks of this application and remove the application file of the indication of these application from computer equipment 14, so as carry out this applications afterwards grid managers 154 can make computer equipment 14 turn back to virgin state.

IPC manager 118 for example uses file transfer protocol (FTP) (FTP), HTTP(Hypertext Transport Protocol) or (Network Attached Storage, file copy NAS) sends application file to computer equipment 14 as the single file such as the zip file of compression from network attached storage.In this zip file relevant for installing and the information of customized application IPC server 122.Expression that this information is by little executable program or extending mark language (XML) document---it is extracted and translation (254) by installation in the grid managers 154 and customization engine (not shown)---.Handle 250 and comprise grid managers 154 installations (256) and operation (258) this application.(256), customization are being installed and are carrying out in the process of (258) using, institute to computer equipment 14 changes and all is logged, so that answer the request of IPC manager 118 and when stopping (260) or unloading and using at grid managers 154, grid managers 154 can be removed this application from computer equipment 14, and removes any other change that (262) are made computer equipment 14 simultaneously when this application of installation and operation.Like this, computer equipment 14 reverts to it in the virgin state of carrying out before using, and all resources on the computer equipment 14 can be used by later application once more.This allows to need not to restart computer equipment 14, and resource just becomes available after operation is used.These changes comprise that branch is used in storage and storer (for example 32) space of operation application code and other change, for example to the distribution of communication port.

In some instances, can move a plurality of application simultaneously on the resource in single computer equipment (for example 14).According to their resource requirement, the application of grid computing environment 100 is partly classified.To use and some of computer equipment are only changed to carrying out the first time of the application of its classification required in order to move, and execution does not subsequently need these changes.In these examples, grid managers 154 only makes a change for carrying out for the first time.In addition, when unloading was used, grid managers 154 was only removed the change for the last application that is performed and stops.

After install using on the computer equipment in grid computing environment 100, grid managers is configured to ask and starts or stops the processing of these application.In internet price configurator (IPC) examples of applications, grid managers 154 is configured to start or stop the IPC server 122 on the computer equipment 14 after on computer equipment 14 IPC server 122 being installed.IPC manager 118 is according to the utilization of the resource in the current grid computing environment 100, and the request grid managers starts or stops the IPC server in the grid computing environment 100.After the IPC server 122 on having stopped computer equipment 14, IPC manager 118 is waited for preassigned time quantum, if indicating, the current then utilization of resources need not start IPC server 122 once more, then IPC manager 118 request grid managers 154 unloading IPC servers 122.In addition, as previously mentioned, grid managers monitor such as computer equipment 14, operation uses the utilization of resources on the computer equipment of (for example the IPC server 120,122,124 and 126), and utilizes information to send to IPC manager 118 this.

In many examples, to the application on the resource in the computer equipment handle to be controlled to be operating system (OS) institute peculiar.Grid computing environment 100 is configured to the different operating system on the process computer equipment.In addition, grid computing environment 100 is designed to handle different application (for example, internet price configurator), and it needn't be redesigned in order to carry out in grid computing environment 100.Grid managers is used with universal mode control and is handled, and this universal mode has reduced the interdependent property between exploitation grid managers code and the Application and Development code.Grid managers provides interface to application code, so that can be found, control (for example start, stop, suspending, continue) and check or monitor the state of handling of using.For the operating system processing that is subjected to the domination of operating system or hosted environment provides interface, and this interface comprises three aspects.An aspect of interface is a deal with data, such as handling sign, state, the degree of resource consumption (bind (socket binding) or use other resource that can use such as CPU (central processing unit) (CPU), storer, socket) and the application specific data that is defined by process data scheme.

The second aspect of interface is a bookkeeping, such as other operation that starts, stops, waiting for, continues, changes priority and defined by the bookkeeping of being supported.

The third aspect of interface is control binding and definition, such as process data scheme, the bookkeeping of being supported and communication bindings.Because the application of not all operation in grid computing environment 100 can be visited this identical information and ability aspect three, therefore using to grid managers provides each to use the inquiry supported and the tabulation of order.

The interface that offers application code is application programming interfaces (API).API is by a group of methods (being embedded in the software code) of grid managers software dictates, utilizes these methods, and the programmer who writes application program (for example internet price configurator) can handle the request from grid managers.

As shown in Figure 4, IPC server 122 comprises API 302 and document 304.Because API302 is applicable to dissimilar application, so document 304 describes how grid managers 154 communicate by letter with IPC server 122 and IPC server 122 supports to pass through what request of API 302.Grid managers 154 read document 304 before starting IPC server 122.In some instances, document 304 usefulness XML are write as, and comprise Doctype description (Document Type Description, DTD) 306.DTD is follow standard generalized markup language (SGML) rule specifically defined.DTD is a kind of standard (specification), and it is followed document and identified what mark separation paragraph, what mark sign topic headings and each mark and will how to be handled.By in document 304, comprising DTD 306, grid managers 154 with DTD " reader " (or " SGML compiler ") just can be handled document 304, and can correctly translate many different types of, documents 304 of using a series of different marker codes and relevance.

Shown in Fig. 4 A, grid managers 154 uses handles 350 application of installing such as IPC server 122.Grid managers 154 reads the DTD 306 in (352) document 304, so that the mark in the identification document 304.Grid managers 154 reads the document 304 of (354) usage flag, so that identification is used for the messaging parameter of communicating by letter with IPC server 122.Grid managers 154 is set up communicating by letter of (356) and IPC server 122 according to the standard of messaging parameter.Grid managers 154 uses messaging parameters to communicate by letter (358) with IPC server 122, so as transmission such as " startup ", " stopping " and " you? " free time request.

Can on network 8, (for example carry out any application, internet price configurator) before, by asynchronous starting, and the relation of they and other grid managers is established grid managers 152,154,156,160,162 and 164 on

computer equipment

12,14,16,18,20 and 22.As shown in Figure 5, handle relation between the 400 initialization grid managers.For each grid managers (for example, grid managers 154), grid managers 154 starts on computer equipment 14 by reading (402) property file.Property file comprises the address list of the computer equipment with grid managers, and described grid managers and grid managers 154 have superior relation.This tabulation is described as first tabulation with all superior relation of other grid managers before.If (404) specified higher level's grid managers (for example grid managers 152) in this address list, then grid managers 154 requests (406) are opened to the communication channel of higher level's grid managers (for example, 152).If grid managers 152 has been activated, then grid managers 152 is by accepting to make response from the request of opening communication channel of grid managers 152.Handle 400 and comprise that grid managers 154 detects (408) from being identified as any communication channel request that has the grid managers (for example grid managers 160,162) of inferior relation with grid managers 154.Determine that there are some requests in (410) if handle 400, then grid managers 154 allows to come from the communication channel of inferior grid managers (for example 160,162).Handle 400 comprise grid managers 154 check (414) whether exist any hang-up, for request to the communication of grid managers with superior relation.If there is the request of any hang-up, then grid managers 154 requests (406) are to the communication channel of grid managers.Resource-query (as previously mentioned) and " heartbeat " message between the grid managers that these communication channels are used between grid managers are all being worked to guarantee each grid managers in the grid computing environment 100.

In case have the grid managers 152,154,156,160,162 and 164 operations of the relation of having set up, grid managers just is used to the proper handling of grid computing environment 100.The function of grid managers usually is enhanced in the life cycle of grid computing environment 100.It is impossible or inconvenient often to close grid computing environment 100 and start the grid computing environment 100 with enhancement function.Configuration grid managers 152,154,156,160,162 and 164 is so that only can cause minimum influence when changing to the user of grid computing environment 100.In order to realize this transparency, for user interface provides API, so that the keeper of grid computing environment 100 can be individually or all visited each grid managers 152,154,156,160,162 and 164 together.This API is static, and reason is that it only comprises a kind of method,, comprises the character string of the order of being keyed in by the keeper that is.API is dynamic, and reason is that this character string can comprise many different orders.

In some cases, grid managers is to use the exploitation of Java programming language.In these situations, can be distributed to the newer command of grid managers by dynamically load java class support new or that revise via Classloader (classloader).Need not to close grid managers in the grid computing environment 100 and just can realize this dynamic access code.Use the java class loader, during the example of the class of each generating mesh manager, the definition of class and behavior can both be updated, thereby provide new function to grid computing environment 100.

The another kind of mode that need not to close grid computing environment 100 and dynamically revise the function of grid computing environment 100 is to change hierarchical relationship between the grid managers, remove grid managers or add new grid managers.The API that provides for the management of grid computing environment 100 also is configured to send to each grid managers and has the character string of order to delete existing relation or to add new relation.

Keeper for grid computing environment 100, grid managers and application on the computer equipment in the visual grid computing environment 100, and be useful to have the grid managers on other computer equipment of a part of form operation mesh-managing level of grid managers of one or more levels inferior relation and to use with this grid managers.The view of these computer equipments is called as grid landscape (grid landscape).As shown in Figure 6, the grid pattern user interface (GUI) 500 that is used for visual grid landscape such as grid computing environment 100 comprises the GUI unit of the tissue of the visual service that moves on computer equipment.GUI 500 provides the fenestral fabric with row and row.Line display service is with respect to the type of the application under the service, service and specific Service Instance and the described service of laminated tissue successively.In each service instance row and the grid computing environment 100, represent that its position by the place of instantiation is associated.In the case, the computer equipment in the grid landscape is shown in tabulation.Specifically, GUI 500 has three row of three

computer equipments

12,14 of expression and 16.GUI 500 illustrates grid managers 152 and moves on computer equipment 12, and

inferior grid managers

154 and 156 operation on

computer equipment

14 and 16 respectively.GUI 500 also illustrates internet price configurator services and moves on computer equipment 12.These internet price configurator services comprise IPC scheduler 116, IPC server 120 and IPC manager 118.

The feedback that utilization comes from grid managers and internet price configurator (or other is used) service dynamically refreshes GUI 500, so that present new service to the keeper in GUI 500.Similarly, from GUI 500, remove pent service.

As shown in Figure 7, grid browser component 600 is the composite figure user interfaces (GUI) that are used for browsing the grid managers on the computer equipment of grid computing environment 100.Assembly 600 shows the figure with bent limit and summit.Computer equipment in the vertex representation grid computing environment 100, and the directional correlation of the grid managers on two computer equipments (summit) in the grid computing environment 100 is represented on bent limit.This association is hierarchical (that is superior/inferior).Each summit shows the network address and the current application that moves of computer equipment on this computer equipment.For example, assembly 600 illustrates the

computer equipment

12,14,16,18,20 and 22 with IPC server 118,120,122 and 124.(not shown) in another example, grid browser component 600 illustrate the association non-level, equity (peer-to-peer) between the grid managers, and use nondirectional limit to represent these associations.
