International Classification:

G06F 1730

US Classification:

707103, 7031041, 709316

Abstract:

The present invention provides a directory service system for accessing a plurality of directory services in a uniform manner. Each directory service manages information relating to objects of that directory service. The type of information that a directory service manages for an object is defined by the object class of the object. An object class defines the properties (i. e. , information) that a directory service manages for objects of that object class. Each property has a property name and property type. A directory service has a property value for each property defined by the object class of each object. The directory service system comprises a schema browsing component, a name resolving component, a binding component, and an extending component. The schema browsing component controls the retrieving of the property name and property type of each property of each object class of each directory service. A client of the directory service system uses the schema browsing component to retrieve property names and property types of the object classes.

International Classification:

US Classification:

709226, 709228, 709229, 709232

Abstract:

The scheduling of a processing job to be performed by at least a portion of a cluster of processing resources distributed across multiple machines. The processing job is associated with a certain entity having a certain amount of guaranteed processing resources on the cluster. If there are enough processing resources to perform the job, then the job may be initiated. On the other hand, if there are not enough processing resources to perform the job, and there are yet some remaining processing resources that are guaranteed to the certain entity, then one or more other jobs that are associated with other entities are at least partially preempted until there are enough processing resources to perform the processing job.

International Classification:

G06F 9/46

US Classification:

718103, 718104

Abstract:

A scheduler for a compute cluster that allocates computing resources to jobs to achieve a balanced distribution. The balanced distribution maximizes the number of executing jobs to provide fast response times for all jobs by, to the extent possible, assigning a designated minimum for each job. If necessary to achieve this minimum distribution, resources in excess of a minimum previously allocated to a job may be de-allocated, if those resources can be used to meet the minimum requirements of other jobs. Resources above those used to meet the minimum requirements of executing jobs are allocated based on a computed desired allocation, which may be developed based on respective job priorities. To meet the desired allocation, resources may be de-allocated from jobs having more than their desired allocation and re-allocated to jobs having less than their desired allocation of resources.

International Classification:

G06F 9/46

US Classification:

718100

Abstract:

A command to perform a task can be received and the task can be started. A command to cancel the task can also be received. The task can be provided with a warning signal and a predetermined grace period of time before cancelling the task, which can allow the task to prepare for cancellation, such as by shutting down cleanly. If the task has not shut down within the grace period, then the task can be cancelled after the grace period expires.

International Classification:

G06F 9/46

US Classification:

718102

Abstract:

Embodiments are directed to managing and verifying licenses in a cluster computer system environment. In an embodiment, a license management application running on a computer system cluster manager receives a job that has multiple job tasks as well as portions of job information. The license management application determines from the job information how many licenses and computer nodes are to be assigned to the job. The license management application checks out the determined number of licenses from a license distributing application on behalf of the received job. The license management application indicates to a scheduler of the computer system cluster manager that one job task is to be run per checked out license.

International Classification:

G06F 9/46

US Classification:

718104

Abstract:

The preemption of running jobs by other running or queued jobs in a system that has processing resources. The system has running jobs, and queued jobs that are awaiting processing by the system. In a scheduling operation, preemptor jobs are identified, the preemptor jobs being jobs that are candidates for preempting one or more of the running jobs. The preemptor jobs include queued jobs, as well as running jobs that are capable of using more processing resource of the system. One of the other running jobs is preempted to free processing resources for the running job that was identified as a preemptor job. Accordingly, not only may queued jobs preempt running jobs, but currently running jobs may preempt other currently running jobs.

International Classification:

US Classification:

709217

Abstract:

Moving data to a remote system and performing computations at the remote system. A method includes receiving from one or more users a plurality jobs. The one or more jobs specify both data to be operated on and the operations to be performed on the data at the remote system. At a data service, one of the jobs to upload to the remote system in priority over other jobs in the plurality of jobs is selected. The method further includes beginning to upload the prioritized job including staging data from the job. At the remote system, once a portion of the data has been received, a service in the remote system begins to perform the specified operation on the data for the prioritized job. Beginning to perform the specified operation is performed prior to all of the data from the prioritized job being uploaded to the remote system.
