Publication number: 20120173917Abstract: A system, method and computer program product for steering a time-of-day (TOD) clock for a computer system having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The method includes receiving, at a processing unit, a request to change a clock steering rate used to control a TOD-clock offset value for the processing unit, the TOD-clock offset defined as a function of a start time (s), a base offset (b), and a steering rate (r). The unit schedules a next episode start time with which to update the TOD-clock offset value. After updating TOD-clock offset value (d) at the scheduled time, TOD-clock offset value is added to a physical-clock value (Tr) value to obtain a logical TOD-clock value (Tb), where the logical TOD-clock value is adjustable without adjusting a stepping rate of the oscillator.Type: ApplicationFiled: February 22, 2012Publication date: July 5, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eberhard Engler, Mark S. Farrell, Klaus Meissner, Ronald M. Smith, SR., Mark A. Check, Evangelyn K. Smith

Publication number: 20110289249Abstract: Interruption facility for adjunct processor queues. In response to a queue transitioning from a no replies pending state to a reply pending state, an interruption is initiated. This interruption signals to a processor that a reply to a request is waiting on the queue. In order for the queue to take advantage of the interruption capability, it is enabled for interruptions.Type: ApplicationFiled: August 3, 2011Publication date: November 24, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Charles W.

Patent number: 6356089Abstract: The invention relates to a contact probe arrangement for electrically connecting a test system with contact pads of a device to be tested. The contact probes are located in guide grooves. The guide grooves as well as areas are provided in a plane parallel to the surface of a guide plate and are covered by a protective plate. The contact probes may bend out laterally into the respective areas. This assures a very dense contact probe array. Contact probe arrays of this type may be used, for example, for detecting opens and shorts in integrated circuits or semiconductor chips. The invention overcomes the problem of adjusting for height differences in the contact pads caused by an uneven surface of the device to be tested.Type: GrantFiled: October 8, 1997Date of Patent: March 12, 2002Assignee: International Business Machines CorporationInventors: Thomas Bayer, Johann Greschner, Klaus Meissner, Werner Steiner, Roland Stoehr
