Реферат: One embodiment of the present invention provides a system that supports space and time dimensional program execution by facilitating accesses to different versions of a memory element. The system supports a head thread that executes program instructions and a speculative thread that executes program instructions in advance of the head thread. The head thread accesses a primary version of the memory element, and the speculative thread accesses a space-time dimensioned version of the memory element. During a reference to the memory element by the head thread, the system accesses the primary version of the memory element. During a reference to the memory element by the speculative thread, the speculative thread accesses a pointer associated with the primary version of the memory element, and accesses a version of the memory element through the pointer. Note that the pointer points to the space-time dimensioned version of the memory element if the space-time dimensioned version of the memory element exists. In one embodiment of the present invention, the pointer points to the primary version of the memory element if the space-time dimensioned version of the memory element does not exist.
