20120144039 | COMPUTING SCHEDULING USING RESOURCE LEND AND BORROW - 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. | 06-07-2012 |
20130125129 | GROWING HIGH PERFORMANCE COMPUTING JOBS - 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. | 05-16-2013 |

20100116239 | Sliding valve assembly - A sliding valve assembly includes a valve body having a fluid conducting port adjacent to a fluid impervious surface. The actuator allows fluid to travel through the valve assembly and into a fluid blocking position where the fluid impervious surface obstructs the fluid from traveling through the valve assembly. First and second sealing assemblies include a primary seal ring, a secondary seal ring around the primary seal ring, and a spring forcing the primary seal ring against a sealing surface. As pressure in the system increases, this pressure is delivered to the sealing assemblies to force them against the sealing surfaces to enhance the sealing relationship. Cams and cam followers affixed to the valve body overcome the frictional forces of the sealing system and the valve body and valve housing to increase the efficiency of the valve assembly and the system in which the valve assembly is used. | 05-13-2010 |
