Abstract: Embodiments of a stacked file system and method are disclosed. One system embodiment includes a memory including a stack that includes a first module and a second module, the first module including executable code that has distinct functionality from executable code of the second module; and logic configured to create a stack template comprising information about the stack.

Abstract: A system and method is provided for efficient access to a data structure by multiple tasks in a computing environment. The data structure can include an ordered arrangement of elements. One operation of the method can include associating a spinlock with the data structure. Another operation may include defining a plurality of traversal iterators, each having a read pointer pointing to an element within the data structure. The traversal iterators can each be associated with a reader task. A further operation can include traversing the data structure using a reader task. The reader task traverses the data structure by using the read pointer of its associated traversal iterator while holding the spinlock. An additional operation may include deleting a selected element from the data structure using a writer task. The writer task can adjust the read pointer of traversal iterators whose read pointers point to the selected element to be deleted while holding the spinlock.
