  • Iteratively de-allocating active objects associated with virtual functions of an adapter
    Patent number: 8832401
    Abstract: A method of managing memory may include selecting an object of a memory heap to be de-allocated and initiating a deferred lock configured to delay de-allocation of the object. The deferred lock may be acquired in response to a thread leaving a computing space, and the object may be de-allocated.
    Type: Grant
    Filed: January 26, 2011
    Date of Patent: September 9, 2014
    Assignee: International Business Machines Corporation
    Inventors: John R. Oberly, III, Timothy J. Torzewski
  • Allocating addressable memory regions to an adapter
    Patent number: 8825981
    Abstract: A method of configuring system memory may include determining a plurality of memory regions supportable on an input/output adapter. The input/output adapter may include a physical function. A memory region of the plurality of memory regions may be allocated to the physical function when an address of the physical function is unknown. The method may further include determining the address of the physical function and associating the address of the physical function with the memory region.

  • Computer system, program product and method for tracking asynchronous I/O with timeout support
    Patent number: 6353845
    Abstract: An apparatus, program product and method of handling tasks that are sleeping and waiting for the completion of I/O operations of other tasks comprises determining a second task which is to await the completion of the I/O operations of a first task, and putting the second task to sleep. A timer is created and associated with the second task. The timer expires when a predetermined wait interval is exceeded. When the timer expires, the sleeping second task is awoken so that a sleeping task is generally prevented from waiting indefinitely for the I/O operations of another task.
