Title: Managing speculative assist threads
Inventor: ARCHAMBAULT ROCH G
IPC: G06F9/44
Filed: 2009-10-16
Granted: 2011-06-07
Abstract: An illustrative embodiment provides a computer-implemented process for managing speculative assist threads for data pre-fetching that analyzes collected source code and cache profiling information to identify a code region containing a delinquent load instruction and generates an assist thread, including a value for a local version number, at a program entry point within the identified code region. Upon activation of the assist thread the local version number of the assist thread is compared to the global unique version number of the main thread for the identified code region and an iteration distance between the assist thread relative to the main thread is compared to a predefined value. The assist thread is executed when the local version number of the assist thread matches the global unique version number of the main thread, and the iteration distance between the assist thread relative to the main thread is within a predefined range of values.

Abstract: A seed depositing device designed to facilitate the uniform distribution of seeds during planting applications. The device includes a tubular outer shell having an open end and at least one opening along its length. An inner core is concentrically located in the outer shell and has at least one row of dimples along the length of an outer surface of the inner core for holding seeds. The inner core fits tightly enough in the outer shell to disallow free movement of the inner core within the outer shell. Rotation means is provided for manually rotating the inner core relative to the outer shell. The inner core is rotatable by the rotation means to align the at least one row of dimples with the at least one opening and expose the at least one row of dimples through the at least one opening. When the inner core is rotated so the openings of the outer shell are aligned with a row of dimples of the inner core, seeds are manually loaded into the exposed row of dimples through the openings of the outer shell. Each row of dimples is successively loaded in like manner until all dimples are loaded with seeds. A reversal of these steps is used to deposit the seeds onto a predetermined area.

Abstract: The number of sub-parts of a closed structure part and the number of steps for manufacturing the closed structure part can be reduced and, therefore, the closed structure part can be efficiently manufactured. In a hemming press step, a punch 84 is further lowered, and a pair of flange portions 20 and 22 is inserted into a slit clearance 102.  At that time, hemming prongs 28 are bent and, each of the hemming prongs 28 sandwiches the flange portion 22. Thus, the flange portion 20, which is one of the two flange portions, is joined to the other flange portion 22. At the same time, a pair of press forming surfaces 96 of the punch 84 presses a metal plate and performs press-forming on a pair of shoulder portions 26 of a blank 24 into a predetermined shape. In this way, the flange portion 20, which is one of the two flange portions, can be fixed to the other flange portion 22 using the hemming prongs 28 (hemming joint). In addition, the pair of shoulder portions 26 of the blank 24 can be press-formed into the predetermined shape.
