Patent number: 7996585Abstract: Disclosed are a method and system of tracking real time use of I/O control blocks on a processing unit basis, in a multiprocessing system, such that in the case of a processing unit failure, a list accurately and concisely identifies the control blocks that need to be recovered. This eliminates the need to scan all the I/O control blocks, greatly reducing the overall system recovery time and minimizing impact to the rest of the running system. The preferred embodiment of the invention uses a task control block structure to record which I/O control blocks are in use by each Processing Unit. Also, the lock word structure defined in the I/O control blocks is provided with an index back into the task control block to facilitate managing the task control block entries.Type: GrantFiled: September 9, 2005Date of Patent: August 9, 2011Assignee: International Business Machines CorporationInventors: Janet R. Easton, Elke Nass, Kenneth J. Oakes, Andrew W. Piechowski, Martin Taubert, John S. Trotter, Ambrose Verdibello, Joachim von Buttlar, Robert Whalen, Jr.

Patent number: 7774519Abstract: A bi-directional and full duplex facility for permitting both the IO processor and the Channel to write CCA messages on their respective queues at the same time. IOP messages to the channel are stored on the TO_CHN queue and Channel messages to the IOP on the TO_IOP queue. CCA Queues replace hardware CCAs due to increasing transmission capabilities of current IO processors and Channel processors. Even though the mechanism is similar, the present invention provides some benefits in the use of signaling. The IOP does not have to signal the Channel each time it puts something on its outbound queue. Each queue contains multiple slots. This allows the IOP and Channel to write multiple messages on the targeted queue without encountering a CCA busy signal. The actual queues are now structured in hardware system memory.Type: GrantFiled: July 3, 2008Date of Patent: August 10, 2010Assignee: International Business Machines CorporationInventors: Daniel F. Casper, John R. Flanagan, Paul S. Frazer, Kenneth J. Oakes, John S. Trotter

Patent number: 7765429Abstract: Disclosed are a method and system for parallel execution of recovery in a non-homogeneous multi-processor environment. The method defines criteria how to decide which recovery actions are to be performed, and on which processor. If multiple recovery actions are pending, the goal is to execute them in parallel on multiple processors. This is much more efficient than the traditional approach of one processor doing all the required recovery. In addition, in large, non-homogeneous systems such a single processor capable of doing the complete recovery might not be existing at all due to technical limitations. The method of this invention also defines rules and mechanisms how multiple processors executing recovery in parallel can access shared resources while avoiding deadlock situations. This includes accessing resources that are currently owned by another processor.Type: GrantFiled: January 27, 2009Date of Patent: July 27, 2010Assignee: International Business Machines CorporationInventors: Ulrich Helmich, Andreas Kohler, Kenneth J. Oakes, Martin Taubert, John S. Trotter

Patent number: 7752497Abstract: Disclosed are a method and system for detecting errors in a computer system including a processing unit to perform tasks to change items. The method comprises the steps of assigning a task control block to the processing unit, and using the task control block to keep track of items being changed by the processing unit. The method comprises the further steps of at defined times, checking the task control block to identify items being changed by the processing unit, and checking the states of said identified items to determine if those states are correct. The preferred embodiment of the invention detects an error when it arises (where possible), and utilizes an infrastructure that allows simple and periodic consistency checks (for example, at designated code points) that detect the error before it causes follow-on problems.Type: GrantFiled: September 9, 2008Date of Patent: July 6, 2010Assignee: International Business Machines CorporationInventors: Joachim von Buttlar, Janet R. Easton, Kenneth J. Oakes, Andrew W. Piechowski, Martin Taubert, John S. Trotter

Patent number: 7600049Abstract: Operations in a multi-processor, multi-control block environment are timed using timing queues and instruction queues. Upon receipt of a request for a subchannel control block (SCB) to perform an operation that needs to be timed, the SCB is queued on one of multiple timing queues based on an elapsed timeout limit (ETL) of the operation. There is an ETL for each operation, and each one the multiple timing queues is associated with an ETL for completing an operation. The SCB may be placed at the bottom of the timing queue, the timing queue ordered from oldest to youngest which allows for quickly checking large numbers of SCBs without having to check every element queue and without having to dequeuing the elements from this queue. Upon receipt of a request to perform a high-priority operation, the SCB may be queued in a high priority instruction queue. The SCB may remain the timing queue to retain its order and be placed on a high priority instruction queue for retrying an operation.Type: GrantFiled: September 14, 2006Date of Patent: October 6, 2009Assignee: International Business Machines CorporationInventors: Kenneth J. Oakes, John S. Trotter

Patent number: 7600053Abstract: An Extended Input/output (I/O) measurement block facility is emulated. The facility provides for the collection of relevant I/O measurement data, and the storing for later efficient retrieval of that data in an extended measurement block. The stored data relates to the performance of an I/O subchannel.Type: GrantFiled: December 28, 2007Date of Patent: October 6, 2009Assignee: International Business Machines CorporationInventors: Scott M.

Patent number: 7587531Abstract: 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 input/output subsystem image includes, for instance, one or more input/output paths. An input/output path of an input/output subsystem image is identified by an input/output path identifier, as well as a physical input/output path identifier.Type: GrantFiled: October 29, 2007Date of Patent: September 8, 2009Assignee: International Business Machines CorporationInventors: Frank W.
