Profile properties in a partition profile are user-configurable through a management entity such as a management console. A partition manager calculates a secondary processing unit entitlement for a logical partition based in part on a secondary processing unit mode property in the partition profile. The secondary processing unit entitlement may be smaller than a primary processing unit entitlement for the logical partition. The partition manager reserves processing units from a secondary shared processor pool equal to the logical partition's secondary entitlement for the logical partition. The primary and secondary processing unit entitlements may be stored in primary and secondary configuration data structures associated with the logical partition. The partition manager may relocate the logical partition to the secondary shared processor pool in response to a predetermined condition.

Managing CPU resources for high availability micro-partitions

A vendor-independent resource configuration interface automatically maps virtual functions to physical functions in a self-virtualizing IO resource using the concept of a logical port that maps to a particular physical port and protocol in the self-virtualizing IO resource. A user wishing to provide a logical partition access to a self-virtualizing IO resource typically creates or configures a logical port for the logical partition by mapping the logical port to a particular physical port and protocol defined for the self-virtualizing IO resource, and an appropriate virtual function mapped to an appropriate physical function on an appropriate self-virtualizing IO resource is automatically selected, typically without requiring the user to have a detailed understanding of the numbers of supported virtual functions, physical functions and protocols supported by specific resources.

A primary processing unit entitlement is determined for a logical partition. A smaller secondary processing unit entitlement is also determined. A partition manager allocates primary processing units to the logical partition from a primary shared processor pool, and the logical partition is activated. The secondary processing units are reserved for the logical partition from a secondary shared processor pool, and the logical partition can be relocated to the secondary shared processor pool in response to a condition such as a hardware failure. The logical partition can continue to process its workload with the fewer processor resources, and can be restored to the primary processing unit entitlement.

A partition manager relocates a logical partition from a primary shared processor pool to a secondary shared processor pool in response to a predetermined condition, such as a hardware failure. The relocated logical partition is allocated a smaller quantity of processing units from the secondary pool than it was allocated from the primary pool. A quantity of processing units reserved for a second logical partition is identified in the secondary shared processor pool, and a portion of those reserved processing units are allocated to the relocated logical partition. The reserved processing units may be redistributed among multiple relocated logical partitions.

A vendor independent interface is provided between a hypervisor and an adjunct partition associated with a self-virtualizing IO resource to effectively abstract away vendor-specific interface details for the self-virtualizing IO resource and its adjunct partition. By doing so, vendor-specific implementation details may be isolated from the configuration and management functionality in a hypervisor, thus minimizing the changes to vendor specific firmware in order to manage new or revised self-virtualizing IO resources.

Accessing vendor-specific drivers for configuring and accessing a self-virtualizing input/output device

Migrating a logical partition (LPAR) from a first physical port to a first target physical port, includes determining a configuration of an LPAR having allocated resources residing on a computer and assigned to the first physical port of the computer. The configuration includes a label that specifies a network topology that is provided by the first physical port and the first target physical port has a port label that matches the label included in the configuration of the LPAR. The first target physical port with available capacity to service the LPAR is identified and the LPAR is migrated from the first physical port to the target physical port by reassigning the LPAR to the first target physical port.

Determining suitable network interface for partition deployment/re-deployment in a cloud environment

Automated management of partition service assignment to a virtual input/output (VIO) adapter is provided. Responsive to creation of a new partition service in a data processing system, a partition priority number is determined for the new partition service, and, for each VIO adapter, the partition priority numbers of the partition services currently assigned to that VIO adapter are summed. For a VIO adapter with a lowest sum of partition priority numbers, logic determines whether assigning the new partition service to that VIO adapter results in its summed partition priority number being above a predefined threshold, and the new partition service is assigned to a VIO adapter based, at least in part, on whether assigning the new partition service to the VIO adapter with the lowest sum of partition priority numbers results in that VIO adapter's summed partition priority number exceeding the predefined threshold.

A method, apparatus, and program product for managing partitionable resources in a logically partitioned computing system is disclosed. The method includes associating each of a plurality of partitionable resources in the logically partitioned computing system with a respective file entry in a virtual file system, associating each of a plurality of partitionable resources in the logically partitioned computing system with a respective file entry in a virtual file system, and allocating a first partitionable resource among the plurality of partitionable resources to a first logical partition among the plurality of logical partitions in response to a file system operation directed to the virtual file system to organize a respective file entry for the first partitionable resource within the respective directory for the first logical partition.

Methods and apparatus associate a computed difference factor to avatars that are to interact with one another in a simulated environment. Applying a difference factor to the avatars enables identification of similar avatars in order to avoid mistaken identities among the avatars. The difference factor predicts probability that one avatar is mimicking another avatar. An attribute uniqueness algorithm may assign the difference factor based on name, appearance, and/or accessory similarity between two avatars. A user index may be used to store data describing attributes of each avatar for analysis using programs that are stored in memory and that execute the attribute uniqueness algorithm. Further, system validation of each avatar provides ability to protect and control likeness of the avatars in the virtual world.

Prevention of a user mimicking another user in a virtual world

Embodiments of the invention generally provide a method, system, and program product for sharing electronic transactions among multiple sharing participants. Embodiments of the invention provide techniques for splitting individual lots into multiple 'shares,' where multiple individuals have an incentive to promote and drive up the price of the lot. Provided the bids reach an acceptable amount, the final selling price is split among each individual in proportion to the number of shares held by each individual.
