    摘要： An embodiment provides for operating an information processing system. An aspect of the invention includes allocating an execution interval to a first logical processor of a plurality of logical processors of the information processing system. The execution interval is allocated for use by the first logical processor in executing instructions on a physical processor of the information processing system. The first logical processor determines that a resource required for execution by the first logical processor is locked by another one of the other logical processors. An instruction is issued by the first logical processor to determine whether a lock-holding logical processor is currently running. The lock-holding logical processor waits to release the lock if it is currently running. A command is issued by the first logical processor to a super-privileged process for relinquishing the allocated execution interval by the first logical processor if the locking holding processor is not running.

    摘要： A method is provided for a first logical processor to determine a running status of a target logical processor of an information processing system. In such method, an instruction is issued by the first logical processor running on the information processing system for determining whether the target logical processor is running. In response to issuing the instruction, a state descriptor belonging to the target logical processor is queried to determine whether the target logical processor is currently running. A result is then returned to the first logical processor, the result indicating whether or not the target logical processor is currently running.

    摘要： In a computing system implementing a virtual memory system having real memory storage frames for storing virtual pages of data and an auxiliary storage system comprising auxiliary storage slots for storing copies of corresponding virtual pages provided in real storage frames, a system and method for freeing auxiliary storage slots to enable further copying of pages thereto. The method comprising the steps of: a) traversing a queue of page frame table entries indicating presence and location of virtual page data in the real storage system; b) determining from the real storage frame backing a page whether the page has been changed in the real storage, and in response, determining whether the page is backed in a corresponding slot in auxiliary storage; c) identifying the auxiliary slot corresponding to the changed frame; and, b) removing the virtual page in said corresponding slot in said auxiliary storage, wherein further room is made available in said auxiliary storage for accommodating storage of other virtual page entries.
