Abstract: A thread protection assembly protects the exposed threads on the pin end and the box end of a section of pipe attached to a coupling. The assembly contains a pin end thread protector and a box end thread protector. The pin end thread protector has a cylindrical sleeve with internal threads adapted to mate with exposed external threads on the pin end of the pipe, an open end, and a closed end having an outwardly projecting hex head. The box end thread protector has a cylinder with external threads adapted to mate with the exposed internal threads on the box end of the coupling and a closed end having an outwardly projecting hex head.

Abstract: An exemplary embodiment of the invention includes methods of configuring a memory block including: providing a memory block, the memory block having a set of addressable memory locations; configuring the memory block to include a plurality of pages corresponding to the set of addressable memory locations, the plurality of pages each having a page size; and allocating at least one of the plurality of pages for storing at least one per-page data structure, the at least one per-page data structure co-located with the memory block. In some embodiments, methods further include: defining the set of addressable memory locations; and computing a number of pages needed to store the at least one per-page data structure. Advantages of the invention include flexible memory allocation. The invention supports a dynamic update of the memory per-page data structures so that the operating system can take full advantage of the available memory.

Abstract: One embodiment disclosed relates to a method of selecting a physical memory locality in a multiprocessor system. A data structure including sets of equidistant localities is provided. A preferred locality is determined using a pointer to a locality within said data structure. Other embodiments disclosed relate to the multiprocessor computing system, the operating system for the multiprocessor computing system, and the data structure for use in selecting a physical memory locality.

Abstract: One embodiment disclosed relates to a method of selecting a default locality for a memory object requested by a process running on a CPU in a multiprocessor system. A determination is made as to whether the memory object comprises a shared-memory object. If the memory object comprises said shared-memory object, then the default locality is selected to be within interleaved memory in the system. If not, a further determination may be made as to whether the memory object comprises a stack-type object. If the memory object comprises said stack-type object, then the default locality may be selected to be within local memory at a same cell as the requesting CPU. If not, a further determination may be made as to whether the requesting process has threads running on multiple cells.
