Abstract: A computer implemented method provides shuffle optimization in map-reduce processing. The computer implemented method obtains intermediate results from a plurality of mappers for an application on a computing device. The intermediate results are combined from the plurality of mappers and are then partitioned into intermediate results for respective reducers for the application. The intermediate results for the respective reducers are stored into a buffer storage, which is partitioned into buffer sections for the respective reducers. Based on a rate of increase in the intermediate results, the method predicts a time at which a data capture notification shall be sent. The method sends the data capture notification based on a predicted time being reached, to indicate that the intermediate results for respective reducers stored in the buffer storage can be transmitted to the respective reducers, and transmits the intermediate results for the respective reducers to the respective reducers.

Abstract: Disclosed is a novel system, computer program product, and method to compute an air quality forecast. An air quality forecast model, air quality real-time monitoring data, and air quality forecast data is accessed. A deviation in air pollution emission is monitored by classifying a difference between the air quality monitoring data and the air quality forecast data. This monitoring includes classifying any weather differences which are caused by weather, classifying any terrain differences which are caused by a geographic terrain; and, filtering the difference caused by inaccurate pollution emission inventory. The monitoring may repeat in response to a given time period elapsing or a chance in air quality forecast data received.

Abstract: A mechanism is provided for detecting air-pollution anomalies. A historical air-pollution pattern is identified for each of a plurality of air-pollution monitoring stations. For each of the plurality of air-pollution monitoring stations, responsive to receiving real-time data from a particular air-pollution monitoring station, the real-time data is compared to the historical air-pollution pattern associated with the particular air-pollution monitoring station. A density difference value is generated based on the comparison of the real-time data to the historical air-pollution pattern associated with the particular air-pollution monitoring station and a determination is made as to whether the density difference value is greater than a predetermined confidence threshold.

Abstract: An HGA loader provides HGAs, in succession, to a multiple workstation head tester. An HGAs carrier station receives HGAs to be tested. An alignment station on the base includes an alignment surface which selectively rotates about an alignment axis. A camera generates images of an HGA on the alignment surface, which is rotated so that the HGA has a desired spatial orientation which is maintained as the HGA is transferred to an HGA testing workstation. A received, oriented HGA is positioned to enable read/write test operations on a disk rotating on an adjacent spinstand. To effect the successive position operations, a transporter includes a track overlying the workstations, and a carriage movable along the track, to pass from workstation to workstations. The loader is automatically operative under the control of a controller.

Abstract: A unitary cartridge, or module, provides a self-contained, high accuracy, ready-to-use assembly for controlling fine positioning of a head gimbal assembly (HGA) disposed on a head mounting unit mounted on the cartridge, with respect to a spinstand or other device associated with a head tester. In a form, the head-mounting unit and a counterweight element are configured to be moveable relative to the base in opposite directions along a displacement axis in response to actuators in the cartridge, and are operative in concert with a damping assembly configured to interact with the counterweight element and the heads mounting unit to mitigate vibrational movement of the cartridge.

Abstract: An apparatus for securing an HGA to a tester includes a housing with a cylindrical cavity disposed about an axis, and having, at its top end, a mounting surface with a central aperture, for receiving an HGA base plate with a boss hole of the HGA overlying the central aperture. Axially elongated clamp fingers, radially dispersed about a spreader pin, move along the axis between (i) a loading position with upper ends extending through and relatively far beyond the central aperture, and (ii) a clamping position with the upper ends disposed at or near the mounting surface. With an HGA on the mounting surface, and the clamp fingers at their loading position, the clamp fingers are driven downward, while simultaneously, the clamp fingers are driven outward by the spreader pin, and the clamp fingers engage boss hole edges, securing the HGA to the tester.
