  • CONSTRAINT STABILIZATION
    Publication number: 20080082309
    Abstract: An improved constraint approach reduces the energy drift rate to acceptable levels. In an embodiment of this approach, massively parallel constrained velocity Verlet NVE (constant particle number, constant volume, constant energy) MD simulations can be run using single precision arithmetic with very low energy drift (e.g., ˜1 Kelvin per microsecond simulated time) using large timesteps (e.g., 2.5 fs) for typical systems and MD force fields.

  • ITERATIVE EXCHANGE COMMUNICATION
    Publication number: 20080082988
    Abstract: An inter-processor communication approach is applicable to a message passing pattern called iterative exchange. In such patterns, two processors exchange messages, then perform a computation, and then this process is repeated. If two sets of send and receive buffers are used, then it is possible to guarantee that a receive buffer on the receiver's side is always available to receive the message. A message passing system controls which buffers are used for sending and receiving. These buffers are registered beforehand, thereby avoiding repeated registration at the time messages are sent. The sender is initially informed of all the possible receive buffers that the receiver will use, and the sender then uses these receive buffers alternately. Examples of this approach can avoid the use of multiple-step rendezvous protocols, memory copies, and memory registrations when a message needs to be sent.

  • METHOD FOR FLIPPING PAGES VIA ELECTROMECHANICAL INFORMATION BROWSING DEVICE
    Publication number: 20080079692
    Abstract: A method for flipping pages of an electronic book via an electromechanical information browsing device that controls page flipping actions of information displayed as an e-book on a display device. The browsing device includes a controller that provides tactile feedback so as to lessen the user-interface differences between conventional books and e-books. Sensors and control mechanisms in the controller generate a series of electrical signals that are interpreted by the computer that displays the e-book to control various browsing operations, such as flipping pages, controlling a rate of page flipping, jumping to pre-set locations in the e-book, etc.

  • NUMERICAL TECHNIQUES FOR DYNAMICS SIMULATION
    Publication number: 20080082303
    Abstract: A method for dynamics simulation involves maintaining quantities according to a floating point binary format quantized to a first precision lower than the precision supported by the floating point format. For example, although an IEEE floating point number can represent numbers with a precision of one part in 2ˆ24, the quantities are quantized to a lower precision, such as one part in 2ˆ22. Operations are applied to sets of the quantities by quantizing the intermediate results of the operations to the lower precision than the precision supported by the floating point format.

  • Rotationally invariant non-coherent burst coding
    Publication number: 20080075176
    Abstract: An apparatus, system and method can be arranged for coding and/or decoding with a phase invariant coding scheme that is useful for short burst signaling devices. 10-bit data is mapped into a 12-bit data with a non-coherent burst code mapper. A parity generator creates a 12-bit parity data to form a 24-bit extended binary Golay code from the 12-bit data. The values for selected bit fields in the 12-bit data and 12-bit parity data are swapped to generate I and Q data such that sensitivity to changes in rotational phase is removed. I and Q data can be used by a transmitter to transmit a rotationally-invariant signal. On receipt, I and Q signals can be recovered, reverse swapped to generate the parity and data signals, and remapped to recover the transmitted 10-bit data. The receiver can also be arranged to use a soft decoding method for improved signal integrity.
