A job submission technique includes a set of algorithms that provide automated workload selection to a batch processing system that has the ability to receive and run jobs on various computing resources simultaneously. The job submission technique provides for organizing workloads, assigning relative ratios between workloads, associating arbitrary workload validation algorithms with a workload or parent workload, associating arbitrary selection algorithms with a workload or workload group, defining high priority workloads that preserve fairness, and balancing the workload selection based on a current status of the batch system, validation status, and the workload ratios.

The apparatus includes a funnel member, a coupling member and retractors. The funnel member is flexible and is frusto-conical in shape. The funnel member proximal end opening is larger than the distal end opening. The funnel member couples to a distal or coupling member that is located at the funnel member distal end portion. The distal or coupling member is rigid and has catches for removably coupling to the retractors. In use, the retractors anchor the apparatus to the patient while allowing the funnel member to be manipulated to force the prosthesis into a surgical cavity of a patient.

In a method of data processing, a database defines a Dial entity and at least one instance of the Dial entity. Each instance of the Dial entity has an input having a plurality of different possible input values and one or more outputs, and each of the plurality of different possible input values has a different associated output value set for the one or more outputs. Each instance of the Dial entity determines a value of at least one of a plurality of configuration latches in a digital system separate from the database. The database also associates with the Dial entity at least one set of biasing weights that, when applied, determines a probability of each instance of the Dial entity having particular ones of the plurality of different possible input values. In response to a call to set the plurality of configuration latches, the database is accessed to apply the at least one set of biasing weights to select one of the plurality of different possible input values for the at least one instance of the Dial entity. The plurality of configuration latches in the digital system are set based upon the output value set for the one or more outputs of the at least one instance of the Dial entity.

A cache memory provides a mechanism for storing and retrieving values wherein a hardware mechanism such as a partial address field selector is combined with an software generated selector in order to access specific congruence classes within a cache. Assignment of software generated selectors to specific types of data can be made in order to allow an operating system or application to efficiently manage cache usage.

Cache and management method using combined software and hardware congruence class selectors

A partitioned cache and management method for selectively caching data by type improves the efficiency of a cache memory by partitioning congruence class sets for storage of particular data types such as operating system routines and data used by those routines. By placing values for associated applications into different partitions in the cache, values can be kept simultaneously available in cache with no interference that would cause deallocation of some values in favor of newly loaded values. Additionally, placing data from unrelated applications in the same partition can be performed to allow the cache to rollover values that are not needed simultaneously.
