Abstract: Repositioning within an input/output device is accomplished without any knowledge of where the input/output device is currently positioned. The input/output device is repositioned to a predetermined position, in order for a program to be retried. The predetermined position is determined from a previously executed program. The previously executed program is scanned looking for commands. For each command found, a position identifier is adjusted based upon the type of command. When the scan and adjustments are complete, the position identifier represents the predetermined position used for repositioning the input/output device.

Abstract: A system and method for storing, saving and printing information in a computer network system, particularly the internet, where a plurality of network server devices are in communication with at least one user device. First a network session is established between a user device and one or more of the network server devices. A display device is provided to show a target page including a plurality of first level link references for selection by the user. Each first level link reference in turn includes subsequent level link references. A server search is conducted to identify all level link references pertaining to a specified server network. The results are in turn stored, printed or saved at a memory location.

Abstract: Apparatus for cooling an electronic device, and a resultant fluid-cooled electronic apparatus are provided. In one embodiment, the apparatus includes a heat sink member with a surface for making thermal contact with the electronic device. The heat sink member has a plurality of channels for carrying coolant fluid. The plurality of channels are positioned in a first group and a second group such that coolant flow alternates across the member. At least one cross-flow opening is provided between at least some adjacent channels of the plurality of channels so that coolant flow can flow within the member between the first group of channels and the second group of channels.

Abstract: The frequency at which a multisystem log stream is compressed by a system of a multisystem environment is adjusted in real-time. The rate at which the multisystem log stream is compressed by the system is ascertained. That rate is relative to how frequently the multisystem log stream is compressed by other systems of the multisystem environment. The frequency with which the system compresses the multisystem log stream is then adjusted in real-time. Thus, the frequency at which one system of the multisystem environment compresses the log stream is relative to the frequency at which other systems of the multisystem environment are compressing the log stream.

Abstract: A method and system for use in a data processing system is proposed, wherein the Input Exponent is used already in the subblocks of the mantissa addition. Early in the flow of a cycle, there are parts of the Potential exponent result generated and put together using zero detect signals and carry select signals of the Carry Select Adder of the mantissa addition. For the addition of two floating point numbers this reduces the number of required logic gates in the timing critical path. This allows a faster cycle time and/or less latency and/or more complex functions. The method and system according to the invention can be applied to adders of different mantissa widths or different exponent widths as well as power of radix 2.

Abstract: Apparatus for cooling an electronic device, and a resultant fluid-cooled electronic apparatus are provided. In one embodiment, the apparatus includes a heat sink member with a surface for making thermal contact with the electronic device. The heat sink member has a plurality of channels for carrying coolant fluid. The plurality of channels are positioned in a first group and a second group such that coolant flow alternates across the member. At least one channel of the plurality of channels has a fluid flow cross-section that varies over a length thereof to selectively enhance a heat transfer coefficient of the coolant fluid within the channel and thereby produce a more uniform temperature at the surface of the heat sink member when making thermal contact with the electronic device.

Abstract: In a network computing environment having a plurality of central processing units, a high performance locking facility coupled to said plurality of central processing units comprising: a processing means for processing multiple requests for locking operations simultaneously and a lock table for creating entries including lock names and lock states. A high-speed searching mechanism for searching any particular lock entry in the table is also provided, as well as means for altering and modifying said table accordingly depending upon any lock status that is being processed. Finally a response and status generator is provided for providing an appropriate response and status of any lock state to other requestors requesting a particular lock.

Abstract: A thermosyphon system is employed in conjunction with compact and/or dense configurations of electrical and/or electronic components to provide cooling. The thermosyphon cooling system is particularly advantageous in those systems in which the compact arrangement of circuit modules precludes the use of direct air cooling. The thermosyphon cooling system repositions the air cooling aspect of its cooling function to an exterior cabinet location distant from the circuit modules which can therefore be placed more closely together to shorten signal paths.

Abstract: A debugging apparatus for debugging a particular application, session or transaction in a computer network environment. The environment includes a plurality of clients in processing communication with one another. The apparatus comprises identifying means for identifying a debugging mechanism to the computing environment, a debug table accessible to the debugging apparatus for storing any pertinent information relating to said debugging apparatus, identifying means for identifying at least one client present in the environment. The debug table stores any and all pertinent information about any identified clients as well as whether or not a particular application, session or transaction needs to be debugged. A determining means is also provided for determining if a particular application, session or transaction needs debugging so that debugging operation can be started accordingly.
