Patent number: 8219995Abstract: 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.Type: GrantFiled: March 28, 2007Date of Patent: July 10, 2012Assignee: International Business Machins CorporationInventors: Diane G.

Patent number: 7698531Abstract: 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.Type: GrantFiled: March 28, 2007Date of Patent: April 13, 2010Assignee: International Business Machines CorporationInventors: Diane G.

Publication number: 20090252057Abstract: 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.Type: ApplicationFiled: April 2, 2008Publication date: October 8, 2009Inventors: DIANE G.
