A mechanism is provided for handling interrupt actions for inter-thread communication. In association with a first processor thread, a thread action data structure is provided that comprises a non-blocking synchronization data structure and an internal list data structure of pending interrupts having no form of synchronization. A post of an interrupt action is received from a second processor thread to the thread action data structure associated with the first processor thread, where the interrupt action is added to the non-blocking synchronization data structure of the thread action data structure. The interrupt action is moved from the non-blocking synchronization data structure to the internal list data structure of pending interrupts for handling by the first processor thread. The internal list data structure of pending interrupts is processed to thereby handle interrupt actions moved to the internal list data structure.

Handling interrupt actions for inter-thread communication

A memory buffer with a set of one or more structures is created by a process of a first software program. The first memory buffer comprises a predetermined amount of memory. It is determined that a structure of the set of one or more structures has been or will be consumed by a second software program that supports the first software program. The consumption of the structure of the set of one or more structures indicates that memory associated with the structure of the set of one or more structures is being reclaimed. In response to the determination that the structure of the set of one or more structures has been or will be consumed, data is written from a first location to a second location. The first location is in memory allocated to the first software program and the second location is indicated for data storage.

Memory management with priority-based memory reclamation

A method of organizing interim software fixes is disclosed. The method includes communicating with a user to understand a first software operation problem and determining if a first interim software fix to remedy the first software operation problem exists within an archive comprising a plurality of interim software fixes. In response to determining the first interim software fix exists, making available to the user an electronic package for installing the first interim software fix to remedy the first software operation problem. In response to determining the first interim software fix does not exist, causing to be developed the first interim software fix to remedy the first software operation problem. The method further includes creating an electronic package for the first interim software fix, making available to the user the electronic package for the first interim software fix and storing information associated with the first software operating problem in the archive.

Method and system for management of interim software fixes

A method, system, device, and article of manufacture for use in a computer memory system utilizing multiple page types, for handling a memory resource request. In a accordance with the method of the invention, a request is received for allocation of pages having a first page type. The first page type has a specified allocation limit. A determination is made in response to the page allocation request of whether the number of allocated pages of the first page type exceeds or is below the allocation limit. In response to determining that the number of allocated pages of said first page type is below the allocation limit, the virtual memory manager enables allocation of pages for the request to exceed the allocation limit.
