Abstract: In a computer system, a method for determining an optimal loop interchange, set of register tiling amount, and cache tiling size for compiling source code into object code. The method first constructs a model of the specific computer system upon which the object code is to be run. Next, the search space comprising all of the different possibilities of the loop interchanges, register tiling amounts, and cache tiling sizes is run through the model to determine estimated times of execution. The particular loop interchange, set of register tiling amounts, and cache tiling sizes corresponding to the best estimated time of execution is then selected as being the most optimal. The source code is then compiled according to this optimal loop interchange, register tiling amount, and cache tiling size.

Abstract: A transmission system is indicated for digital signals combined into a multiplex signal, and a network element for such a transmission system. Each network element contains an adapter circuit to balance phase variations in an incoming multiplex signal. The adapter circuit has a buffer memory (1) for payload data bytes, a write address generator (2) which controls the buffer memory (1) in a way so that a number of payload data bytes is stored within one write cycle, and has a read address generator (3) which controls the buffer memory (1) in a way so that the number of payload data bytes stored within the write cycle is greater than the number of payload data bytes read during the read cycle. Each network element has a sort facility (5) which sorts the read payload data bytes, so that a multiplex signal that is transmitted by a network element has the established frame format.

Abstract: Network elements of a synchronous digital communications system have a clock generator for generating a clock signal locked to an input signal. Such a clock generator comprises a tunable oscillator (OSC) and a phase comparator (PK) for comparing the phase of the input signal (IN) with the phase of the clock signal (CLK) and for generating a correction signal which serves to tune the oscillator (OSC). To avoid phase transients due to interruptions and disturbances in the input signal (IN), means (WD) are provided for determining an expectancy window, for deciding whether the correction signal lies within the expectancy window, and for tuning the oscillator with the correction signal if the correction signal lies within the expectancy window.

Abstract: A device for automatically closing a closure installation (such as a window or a door) includes a drive device, a traction mechanism, a spring, an actuating device and a locking device. The closure installation is mounted in a frame supported by a building. The traction mechanism is located between the closure installation and the frame, and is driven by the drive device to close the closure installation. The spring is tensioned when the closure installation is placed in the open position, and supplies the energy to the drive device which is required to close the closure installation. The actuating device is used to initially place the closure installation in the open position. The actuating device tensions the spring when the closure installation is placed in the open position. The locking device is initially released to permit the closure installation to be placed in the open position.

Abstract: The network elements NE1, . . . , NE6 of a synchronous digital communications system must be synchronized with each other without the possibility of clock loops occurring. A network node NODE contains network elements NE1, . . . , NE6 and a central clock generator SASE. The network elements transmit clock signals 2M to the clock generator, which contain a clock of a message signal STM-N and a quality indicator (SSM) contained in the message signal which reflects the accuracy of the clock. The clock generator selects one of the clock signals 2M as the reference clock REF and informs the control installation STE which of the clock signals it has selected and the degree of accuracy of this clock signal. On the basis of this message STAT the control installation gives instructions ANW to the network elements with respect to the quality indicator which the network elements are to transmit to their outputs.

Abstract: An apparatus, to be used in a desynchronizer, for minimizing the output jitter of the desynchronizer. The desynchronizer is assumed to include a bit buffer for staging data that is to be output. The desynchronizer is also assumed to include a means for decoding the input signal to determine how justification opportunities in the input signal are used and therefore what justification bits must be leaked by the desynchronizer. The apparatus and method of the present invention uses the information about the incoming justification bits or incoming justification bytes and the state of the buffer to determine the longest possible time to wait before issuing a command to momentarily speed up or delay outputting the next data unit from the bit buffer.

Abstract: The indicated test method makes it possible to test clock paths via which a reference clock is transmitted to synchronize network elements in a synchronous digital telecommunications system. To that end the reference clock is marked at the start of the clock path being tested by modulating information thereon. It is observed at the end of the clock path being tested whether the reference clock contains the information modulated thereon at the start. This information is configured so that it does not impair the operation of the synchronous digital telecommunications system. A network element is furthermore indicated, which is in a position to produce by itself the phase modulation required for a test, through its clock generator.

Abstract: In digital transmission systems, such as synchronous transmission systems according to the SDH/SONET standard, there is a need to have information on the synchronization status of the system. A known approach is to monitor the pointer activity. This is disadvantageous in that because of a hysteresis in the pointer processor, information derived from the pointer activity only conditionally reflects the synchronization status. In a network element (1) according to the invention which forms part of a transmission system of the above type, at least one interface unit (2, 3, 4) contains, besides an optical-to-electrical transducer (5), a synchronization-monitoring device (6) which derives a synchronization status parameter, e.g., TIE, RMSTIE, by comparing an external clock frequency (T.sub.e) with an internal clock frequency (T.sub.i). For this, the synchronization-monitoring device (6) comprises a phase-comparing device (37), a memory device (25), and an evaluating device (26).

Abstract: A network match making method and system matches an additional computer executing an instance of a client computer program with one or more other computers executing instances of client computer programs. The computers are linked by one or more communication links. A match maker computer program receives a request from the instance executing on the additional computer to match with an instance executing on another computer. A measurement request is sent to the instance executing on the additional computer. Communication attributes between the additional computer and each existing computer are measured and an existing computer is selected as a match for the additional computer if one of the communication attributes exceeds a minimum performance requirement. Existing computers can be further selected based on further attributes. If none of the communication attributes meets the minimum performance requirement, a match maker program waits for a further request.

Abstract: In synchronous digital communication systems using a synchronization quality marker (SSM), timing loops can be created. To avoid such timing loops, a synchronous digital communication system is provided having network elements (NE11, . . . , NE33) in which two classes (top, bottom) are defined for interface units (S.sub.1, . . . , S.sub.x, . . . , S.sub.X+i).

Abstract: A device for printing stock standing on one edge, in particular a piece of mail in a postage meter and/or addressing machine, includes a guide plate for the stock which is inclined relative to the vertical and has a recessed region for a printing device. A rotating conveyor has a conveying plane which extends orthogonal to the guide plate and on which the stock stands on one edge and is transported in one direction while resting against the guide plate. The recessed region includes at least one cutout and a region of the guide plate downstream of the cutout is so far recessed from a bearing surface for the stock that there is no contact with the latter in this location. This ensures sufficient penetration time for the ink and prevents smearing of the printed image. The printing device is an ink jet printing device which is stationary during printing and which has a nozzle plane that extends parallel to the guide plate. The guide plate is inclined a maximum of 45.degree. from vertical.
