Abstract: The invention relates to a pulling machine for unloading and laying railway tracks, which moves by means of caterpillar tracks running next to the sleepers arranged on the setting bed, with the rail on the provisional supports arranged on the sleepers. The machine comprises a cabin and two caterpillar tracks and includes, in its rear tractor part, a pulling slide that comprises a tube with fastening elements, said tube sliding horizontally, actuated by a hydraulic cylinder comprising a piston connected to the tube, via three dismountable metal supports provided with teflon elements for facilitating the sliding, said metal supports being connected to steel elements acted upon by articulated arms generating the vertical movement by means of the action of another hydraulic cylinder, always maintaining the pulling direction. The machine pulls the rails without needing an auxillary track, maintaining the position of the track-laying train.

Abstract: Exemplary embodiments include a method, system, and storage medium for managing computer processing functions in a multi-processor computer environment that includes a standard logical processor and an assist logical processor, each of which share the same operating system instance within a logical partition. The method includes invoking a switch-to service by standard code. The standard code is running on a standard logical processor and is executing a task. The switch-to service checks to see if an assist logical processor is online, and it if finds one, the switch-to service updates an integrated assist field of a work element block associated with the task and assigns a queue to the work element block. The task is dispatched, in accordance with business rules identified in a system control block, on either of said assist logical processor or said standard logical processor.
