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.

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, data processing system, and computer program product for processing instructions. The instructions are processed by a processor unit while using a first table in a plurality of tables to predict a set of instructions needed by the processor unit after processing of a conditional instruction. An identification is formed that a rate of success in correctly predicting the set of instructions when using the first table is less than a threshold number. A sequence of the instructions being processed by the processor unit is searched for an instruction that matches a marker in a set of markers for identifying when to use the plurality of tables. An identification that the instruction that matches the marker is formed. A second table from the plurality of tables referenced by the marker is identified. The second table is used in place of the first table.

摘要： A method, system and computer program product enables the granular collection and utilization of hardware statistical samples for the efficient scheduling and allocation of data processing resources. In particular, a Partition Statistics Capture and Analysis (PSCA) utility utilizes special purpose registers to collect statistical samples, such as: (1) instructions completed; (2) Level2 (L2) cache misses; (3) cycles per instruction (CPI); and/or (4) other statistics selected based on the programming of the PSCA utility. Further, these statistical samples are utilized for the several purposes, including: (1) determining how long (time) the footprint of a partition takes to become established during the “cold start” period, i.e., during system instantiation; (2) detecting movement of the CPI curve in order to determine the (shifted) location of the onset of steady state (i.e., the knee) on the CPI curve; and (3) utilizing the statistical samples to guide dispatch decisions and make tuning recommendations.

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 method and system for replacing physical connections within a large enterprise system with wireless connections. A first wireless transceiver is associated with a node, wherein the node comprises one or more system service processors. A second wireless transceiver is associated with a main system service processor. System service processors associated with the node, referred to as node service processors, are assigned a unique identification (ID), e.g., a name and/or number, to identify the node service processors during wireless connection. An Ethernet cable is utilized to connect the node service processors to the main system service processor. The unique identification is transferred from the main system service processor to the node service processor, and then the Ethernet cable is disconnected. When the Ethernet cable is disconnected, the node service processor(s) communicate with the main system service processor via a wireless network utilizing the transceivers and unique IDs.
