Abstract: A method comprising flowing a liquid through supply pipe couplings to a fin tube assembly of an air-to-liquid heat exchanger and through the fin tube assembly to return pipe couplings, wherein the fin tube assembly forms a central air flow pathway. The method further comprises passing air through components within a rack secured to the rear door heat exchanger and through the fin tube assembly and detecting an operating condition within the rack. The method then automatically moves the fin tube assembly from a retracted position to an extended position in response to the operating condition, wherein the retracted position directs substantially all of the air to exit the rack through the central air flow pathway, and wherein the extended position allows the air to exit through the central air flow pathway and also through first and second side air flow pathways.

Abstract: An air-cooling apparatus is provided which includes a securing mechanism for holding two or more separate electronics racks in fixed relation adjacent to each other, and a multi-rack door sized and configured to span the air inlet or air outlet sides of the racks. The securing mechanism holds the electronics racks in fixed relation with their air inlet sides facing a first direction, and air outlet sides facing a second direction. The door includes a door frame with an airflow opening. The airflow opening facilitates the ingress or egress of airflow through the electronics racks, and the door further includes an air-to-liquid heat exchanger supported by the door frame, and disposed so that air flowing through the airflow opening passes across the heat exchanger. In operation, the heat exchanger extracts heat from the air passing through the separate electronics racks.

Abstract: An apparatus for avoiding a damaged region on a touchscreen is disclosed. A method and a computer program product also perform the functions of the apparatus. The apparatus includes a damage location module that determines a location of an area of damage on a touchscreen of a computing device. The area of damage includes damage to the touchscreen. The apparatus, in one embodiment, includes a display location module that determines a location of one or more display items commanded to be displayed on the touchscreen. Each display item includes a location to be displayed on the touchscreen. The apparatus includes, in one embodiment, a rearrangement module that alters a location of a display item to be displayed in the area of damage where the display item is moved to a location on the touchscreen outside the area of damage on the touchscreen.

Abstract: A method, system, and computer program product for processing an application in a high performance computing (HPC) data center are described. The method includes analyzing and sorting a plurality of nodes in a cluster of the HPC data center into a plurality of frequency bins, each of the plurality of nodes being sorted into more than one of the plurality of frequency bins based on performance. The method also includes analyzing and sorting the application into an application bin among a plurality of application bins based on a frequency scaling characteristic of the application. The method further includes selecting a first set of nodes among the plurality of nodes to process the application, the first set of nodes being sorted into a first frequency bin among the plurality of frequency bins corresponding with the application bin of the application.
