  • Gathering I/O measurement data during an I/O operation process
    Patent number: 7174274
    Abstract: I/O measurement data associated with the performance of an I/O operation process is gathered during the I/O process. The I/O measurement data is saved in an IRB memory location specified by a test subchannel instruction. An I/O interrupt signals the completion of the I/O operation process.

  • Predictably defining input/output configurations for environments employing fabrics
    Patent number: 7149821
    Abstract: In an environment employing a fabric, such as a cascading switch network, a predictable input/output (I/O) configuration is provided. The I/O configuration explicitly specifies the one or more peripheral units accessible by a program, such as an operating system. Other peripheral units not specified in the I/O configuration are not accessible, thus, providing a secure environment.

  • Filter turning point detection
    Patent number: 7103514
    Abstract: Disclosed are a method and system for detecting point. The method of this invention comprises the steps of providing a set of points representing measured time delays between two clocks, providing a turning indicator to measure a magnitude of turns per measurement interval, and identifying a turn at a given point when the turn indicator at said given point is above a given value. With the preferred embodiment of the invention, the turn indicator is given by the equation: turn_indicator=(rtt_min?rtt_estimate)/number_of_points; where rtt_min is the minimum round trip delay in all the measurement points, and rtt_estimate is estimated round trip delay by using the symmetric convex hull algorithm.

  • Extended input/output measurement facilities
    Patent number: 7000036
    Abstract: Input/output (I/O) measurement facilities are provided. An extended I/O measurement block facility is provided that enables measurement blocks to be stored in discontiguous areas of main storage and to be accessed directly via addresses. In a further aspect, an extended I/O measurement word facility is provided that facilitates the obtaining of measurement data for single I/O operations.

  • Method, system and program products for enhancing input/output processing for operating system images of a computing environment
    Patent number: 6996638
    Abstract: An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. An input/output subsystem image is identified by an input/output subsystem image identifier, which is used by various programs to designate the particular input/output subsystem image for which an I/O operation is to be performed. An operating system is provided with access to a plurality of input/output subsystem images of the input/output subsystem. One or more controls are provided to the operating system image to enable the operating system image to access the plurality of input/output subsystem images.

  • Managing access, by operating system images of a computing environment, of input/output resources of the computing environment
    Publication number: 20040230757
    Abstract: An input/output subsystem is configured as a plurality of input/output subsystem images, each of which appears to a program as an independent input/output subsystem. In response to an operating system image submitting an input/output (I/O) request requesting access to an input/output subsystem image, a determination is made as to whether the operating system image is authorized to access the input/output subsystem image. In response to the access being authorized, the I/O request is authorized.
