Abstract: Systems, apparatuses, and methods for implementing a message passing system to schedule work in a computing system. In various implementations, a processor includes a global scheduler, and a plurality of local schedulers with each of the local schedulers coupled to a plurality of processors. The processor further includes a shared cache that is shared by the plurality of local schedulers. Also, a plurality of mailboxes are implemented to enable communication between the local schedulers and the global scheduler. To schedule work items for execution, the global scheduler is configured to store one or more work items in the shared cache and store an indication in a mailbox for a first local scheduler of the plurality of local schedulers. Responsive to detecting the message in the mailbox, the first local scheduler identifies a location of the one or more work items in the shared cache and retrieves them for scheduling locally.

Abstract: Systems, apparatuses, and methods for implementing a hierarchical scheduler. In various implementations, a processor includes a global scheduler, and a plurality of independent local schedulers with each of the local schedulers coupled to a plurality of processors. In one implementation, the processor is a graphics processing unit and the processors are computation units. The processor further includes a shared cache that is shared by the plurality of local schedulers. Each of the local schedulers also includes a local cache used by the local scheduler and processors coupled to the local scheduler. To schedule work items for execution, the global scheduler is configured to store one or more work items in the shared cache and convey an indication to a first local scheduler of the plurality of local schedulers which causes the first local scheduler to retrieve the one or more work items from the shared cache.

Abstract: A method for hierarchical work scheduling includes consuming a work item at a first scheduling domain having a local scheduler circuit and one or more workgroup processing elements. Consuming the work item produces a set of new work items. Subsequently, the local scheduler circuit distributes at least one new work item of the set of new work items to be executed locally at the first scheduling domain. If the local scheduler circuit of the first scheduling domain determines that the set of new work items includes one or more work items that would overload the first scheduling domain with work if scheduled for local execution, those work items are distributed to the next higher-level scheduler circuit in a scheduling domain hierarchy for redistribution to one or more other scheduling domains.

Abstract: Wafer sort data can be converted to binary data, whereby each integrated circuit of the wafer is assigned a value of one or zero, depending on whether test data indicates the integrated circuit complies with a specification. In addition, each integrated circuit is assigned position data to indicate its position on the wafer. A frequency transform, such as a multidimensional discrete Fourier transform (DFT), is applied to the binary wafer sort data and position data to determine a spatial frequency spectrum that indicates error patterns for the wafer. The spatial frequency spectrum can be analyzed to determine the characteristics of the wafer formation process that resulted in the errors, and the wafer formation process can be modified to reduce or eliminate the errors.

Abstract: A field assembled gas riser includes an adapter having plural inner grooves that receive the outer surface of a plastic gas line as it is plastically deformed by axial insertion of a stiffener into the gas line. The gas line is terminated at a desired location, the adapter slid over the terminated end, and a stiffener manually inserted into the gas line. Continued axial advancement of the stiffener acts as a mandrel to plastically deform the gas line into the grooves and provide a secure, sealed arrangement.

Abstract: A system for automatically tracking a surface for performing a welding operation comprises a frame and pair of ring gears movably mounted to the frame. The ring gears are spaced apart from each other. Three weld heads are movably mounted to each ring gear. Each weld head has a welding torch for providing a weld and a laser scanning device for scanning a surface and for measuring distances over the surface. A control system communicates with the laser scanner for receiving the measured distances and for controlling the movement of the ring gears and the weld heads.

Abstract: A panel of monoclonal antibody (Mab) producing hybridomas directed against various antigens of Bordetella pertussis are disclosed herein. The hybridomas and the antigens that the resulting monoclonals are directed against include: (1) BPG10F8C3 and BPE8D8B1--lipooligosaccharide A (LOS A), serotype 1; (2) BPD5, BPE6, and BPF2--fimbriae, serotype 2; (3) BPE3, BPE8 and BPD8--69 kDa nonfimbrial protein, serotype 3; and (4) BPB7, BPC10, BPD4, BPD6, BPD9, and BPF5--fimbriae, serotype 6.

Abstract: The present invention comprises a method for the purification of the 69 kDa outer membrane protein of Bordetella B. pertussis and the protein purified therewith. A preferred embodiment comprises the purification of the 69 kDa protein from Bordetella B. pertussis strain Bp 353. The present process is advantageous in that it does not require or involve the use of biologics (such as monoclonal antibodies) and therefore simplifies the purification procedure and makes the resulting purified protein particularly advantageous for inclusion in acellular vaccines.

Abstract: Apparatus for automatically measuring and recording, in a seqential manner, various parameters such as capacitance, dissipation factor and insulation resistance, of each of a plurality of capacitors under substantially identical test conditions.

Abstract: Test fixtures, each being adapted to receive a capacitor, are connected through a relay network to a time variable high voltage source. Predetermined relays are energized in a predetermined sequence to connect a given capacitor to the source. A high voltage signal having a predetermined waveform is applied to the capacitor associated with an energized relay. When the current through the given capacitor exceeds a threshold, the voltage value then being applied to the capacitor determines the breakdown voltage of the capacitor.
