A system and method are provided for synchronizing threads in a divergent region of code within a multi-threaded parallel processing system. The method includes, prior to any thread entering a divergent region, generating a count that represents a number of threads that will enter the divergent region. The method also includes using the count within the divergent region to synchronize the threads in the divergent region.

A test stand arrangement includes at least one electric motor (4) connected to a test specimen for driving and/or loading the test specimen, and a control arrangement for the or each electric motor. In order to be able to create the connection of the drive train and vehicle simulation with the real, vehicle-specific combustion and dynamic behavior of the engine, at least one model for a multi-mass flywheel is implemented in the control arrangement, from which model at least a part of the control requirement for the or each electric motor is calculated and which model contains at least the two masses of the primary and secondary side of the multi-mass flywheel and a substitute model for the or each bow spring, and an algorithm is implemented in the control arrangement that analyzes the model for a multi-mass flywheel by means of an integrated time step method.

One embodiment of the present invention sets forth a technique for dynamically allocating memory using a nested hierarchical heap. A lock-free mechanism is used to access to a hierarchical heap data structure for allocating and deallocating memory from the heap. The heap is organized as a series of levels of fixed-size blocks, where all blocks at given level are the same size. At each lower level of the hierarchy, a collection of N blocks in the lower level equals the size of a single block at the level above. When a thread requests an allocation, one or more blocks at only one level are allocated to the thread. When threads are finished using an allocation, each thread deallocates the respective allocated blocks. When all of the blocks for a level have been deallocated, defragmentation is performed at that level.

Embodiments of the invention relate to a cover for a dryer. The dryer is adapted, when in operation, to heat a gas stream. The dryer includes a cover mounted to at least one section of an outer wall of the dryer, in particular a rear wall of the dryer. A passage through which the gas stream can flow is formed, at least sectionwise, by the cover. The cover can include a heating unit having at least one heating element such that the gas stream flows around the heating element when the dryer is in operation.

The current subject matter provides techniques in which stored value from a stored value account can be redeemed at two or more backend stored value account processors in either a single transaction or multiple transactions. Techniques are also described for redeeming stored value from stored value accounts that correspond to bundled items. Related apparatus, systems, techniques and articles are also described.

A landscape edging member for use in defining borders of walks, patios, driveways and the like, is provided with edge lips on one side of a base wall, which serve as stops when one of the landscape edging members is inverted and nested with another landscape edging member, to prevent lateral shifting of the nested landscape edging members when they are placed in a stack or bundle. The lips of the nested landscape edging members overlap portions of the vertical walls of the other one of the two nested landscape edging members, which form an inverted pair of landscape edging members. The lips are high enough from the base wall to prevent lateral shifting of the nested pair when a stack of the landscape edging members are shipped.

Single pellets of a thermoplastic resin containing long glass fibers and a conductive filler are set forth that enable molded articles made from these pellets to exhibit conductivity and, at the same time, high mechanical properties. These pellets have mechanical properties that are substantially equivalent to non-conductive pellets of a thermoplastic resin containing same loading of long glass and provide conductivity that is substantially equivalent to articles obtained by blending two kinds of pellets, one pellet having a conductive filler and the other pellet one containing long glass fibers. The pellets include a thermoplastic resin, a long fiber reinforcing filler and a conductive additive dispersed in the pellet.

A method for determining a rate of change of longitudinal direction of a subterranean borehole is provided. The method includes positioning a downhole tool in a borehole, the tool including first and second surveying devices disposed thereon. The method further includes causing the surveying devices to measure a longitudinal direction of the borehole at first and second longitudinal positions and processing the longitudinal directions of the borehole at the first and second positions to determine the rate of change of longitudinal direction of the borehole between the first and second positions. The method may further include processing the measured rate of change of longitudinal direction of the borehole and a predetermined rate of change of longitudinal direction to control the direction of drilling of the subterranean borehole. Exemplary embodiments of this invention tend to minimize the need for communication between a drilling operator and the bottom hole assembly, thereby advantageously preserving downhole communication bandwidth.
