Abstract

An apparatus and method for temporarily slaving and configuring a plurality of hardware resources such as computers, microprocessor-based devices, and the like, over a network, and then emancipating the resources to operate independently. Resources or targets may be enslaved at an operating system level. A controller may configure a plurality of hardware resources such as computers, microprocessor-based devices, and the like, to operate autonomously over a network. Resources or targets may be enslaved at an operating system level, configured with commands from a controller, and emancipated to operate independently. Emancipated resources may download applications, read and write files, communicate with other devices, and otherwise operate as independent computers. Data corresponding to test instructions may be downloaded from, and data corresponding to results may be recorded and saved on, a network server by a resource operating independently. Upon completion of a test or a series of tests, a resource may again report back to a controller, be enslaved and reconfigured, and be emancipated to operate other test software.

Claims

a controller operably connected to a network to communicate data with the target over the network, the controller comprising;

a second network interface operably connected to the network to communicate data between the controller and the network,

a second processor operably connected to the second network interface for selectively, based on resource information received from the target and temporarily providing operating system command line instructions for controlling the operating system of the target, while the operating system of the target is continuously operating, to configure the target,

a second memory device for storing data communicated to and from the second processor, and

a storage device connected to the network for storing files of data.

2. The apparatus of claim 1 wherein the controller is further provided with a launcher for communicating with the target, and for enslaving and controlling the operating system of the target during a setup operation to configure the target.

3. The apparatus of claim 2 wherein the second processor is programmed to emancipate the target to operate independently after the setup operation, and the target is configured to load and run an application independently of the controller.

4. The apparatus of claim 1 wherein the controller is further provided with a resource manager for managing data corresponding to identification and performance characteristics of the target, and to availability of the target to run applications.

5. The apparatus of claim 1 wherein the controller further comprises a server for storing and retrieving files.

6. The apparatus of claim 5 wherein the files comprise datafiles selected from applications for running on the first processor, control applications containing executables for controlling loading and running of the applications, application datafiles containing data corresponding to parameters used by the first processor in running the applications, and result datafiles containing data corresponding to results output by the first processor while running the applications.

7. The apparatus of claim 1 wherein the controller is further provided with a database manager for storing and retrieving application datafiles and result datafiles communicated between the first processor and the storage device.

8. The apparatus of claim 1 wherein the controller is further provided with a scheduler for acquiring data corresponding to a queue of applications to be run, scheduling to run an application associated with the queue, confirming that all data needed to run the application has been assembled, and monitoring the target to determine completion of running of the application.

9. The apparatus of claim 8 further comprising a database manager for storing, and for retrieving over the network, application datafiles and result datafiles.

10. The apparatus of claim 9 further comprising a resource manager for acquiring and storing data corresponding to identification and characteristics of the target, and to availability of the target to run applications.

11. The apparatus of claim 10 further comprising a launcher for communicating commands to the operating system of the target for configuring the target prior to emancipation of the target to operate independently.

12. The apparatus of claim 11 further comprising a server for transferring files communicated over the network to and from the storage device.

13. The apparatus of claim 1 further comprising a plurality of targets, the target being a first target of the plurality of targets.

14. The apparatus of claim 13 wherein a second target of the plurality of targets is provided with a second operating system different from the first operating system.

15. The apparatus of claim 1 wherein the target further comprises a storage device operably connected to the first processor for storing application datafiles, result datafiles, and applications.

16. The apparatus of claim 1 wherein the target is provided with an operating system for downloading an executable to be run on the first processor.

17. The apparatus of claim 16 wherein the executable is selected from a command file, an interpretable language file, a batch file, and an instruction file written in machine code.

18. The apparatus of claim 1 wherein the target is provided with an operating system for receiving executables downloaded by the controller to be run on the first processor.

19. The apparatus of claim 1 further comprising a second target operably connected to the network and having a second operating system different from the first operating system.

20. The apparatus of claim 1 wherein the second memory device is provided with a plurality of queues for receiving operational codes communicated by a plurality of processes running on the second processor, each operational code being readable by a process of the plurality of processes for controlling an operation of the process.

21. The apparatus of claim 1 wherein the second processor is programmed to run simultaneously a plurality of software modules, the plurality of software modules comprising:

a database manager for storing and retrieving application datafiles to be used as inputs for applications executable by the second processor, and result datafiles containing outputs of the applications;

a resource manager for storing data corresponding to identification, characteristics, and availability of the target to run the applications;

a launcher for communicating with the operating system of the target and for configuring the target to operate independently of the controller in running applications and uploading result files to the server, and for selectively downloading applications to the target and instructing the target to download applications to the target result datafiles to the server; and

a scheduler for acquiring data corresponding to applications to be run, selecting applications to be identified to the target for downloading to the target, and for spawning instantiations of the launcher.

22. A method of running software on a plurality of computers, the method comprising:

connecting a target to a network, the target comprising;
