摘要： A system, method and computer-readable medium for balancing access among multiple logical partitions to the physical system resources of a computer system employing system virtualization. Each of the logical partitions is classified, initially during a startup period, in accordance with a level of allocated dispatch window utilization. Performance metrics of one or more of the physical system resources are determined in association with one or more of the logical partitions. The performance metrics determination is performed at a hardware level independent of programming interrupts. During a dispatch window in which a given set of the physical system resources are configured for allocation to one of the logical partitions, the given set of physical system resources are re-allocated to a replacement logical partition in accordance with the determined performance metrics associated with the replacement logical partition and the dispatch window utilization classification of the replacement logical partition.

摘要： A system and technique for managing rollback in a transactional memory environment is disclosed. The system includes a processor, a transactional memory, and a transactional memory manager (TMM) configured to perform a rollback on the transactional memory. The TMM is configured to, responsive to detecting a begin transaction directive by the processor, detect an access of a first memory location of the transactional memory not needing rollback and indicate that the first memory location does not need to be rolled back while detecting an access to a second memory location of the transactional memory and indicating that a rollback will be required. The TMM is also configured to, responsive to detecting an end transaction directive after the begin transaction directive and a conflict requiring a rollback, omit a rollback of the first memory location while performing rollback on the second memory location.

摘要： A method, apparatus, and computer program product for running software on an adapter. In response to a connection of a hardware interface for the adapter with a current host computer, a processor unit in the adapter determines whether a set of protocols for communicating with the current host computer to access resources is present on the adapter. In response to the set of protocols being absent on the adapter, the processor unit obtains the set of protocols from the current host computer. The processor unit identifies a set of available resources in the current host computer for use by the adapter using the set of protocols. The processor unit runs software stored on a set of storage devices in the adapter using the set of available resources identified for use by the adapter.
