An editing mode is provided to associate the audio file with a media segment according to a timeline. The clip-beat aligner aligns a boundary of the media segment with a musical beat on the timeline. Upon performing an editing operation, the clip-beat aligner maintains that the boundary of the media segment is aligned with any one of the musical beats. To align a boundary of each media segment with a musical beat, the clip-beat aligner identifies a musical beat that is proximate to the position of the media segment's boundary. The clip-beat aligner then aligns the media segment's boundary with the proximate musical beat by, if necessary, automatically trimming the media segment's duration such that the media segment's boundary occurs at the same moment in time as the proximate musical beat. |

Bit error detector for iterative ECC decoder
An iterative decoder includes at respective variable nodes, that is, at nodes that correspond to the bits of the code word, bit error detectors that after convergence determine if the respective hard decision bit values have changed from the bit values provided by the channel. The change in value for a given bit indicates that a bit error has been corrected. The bit error detector, for message-passing decoders that perform calculations by addition rather than multiplication, can be readily implemented as an XOR gate. Thus, a bit error is detected at the variable node by XOR'ing the sign bits of the input symbol and the variable node sum. After convergence, the output values produced by the bit error detectors at the respective variable nodes are added together using an adder tree that accumulates the detected bit errors for an entire date block, or ECC code word. Alternatively, the system may group the bits into respective code word symbols and combine the bit error values into symbols-with-errors values using, for example, XOR sub-trees that produce, for each symbol, a single error value. The error value for a given symbol indicates that the symbol is either error-free or includes one or more bit errors, and a total count of the symbols with errors is produced by adding the error values together. |

Method and apparatus for testing request-response service using live connection traffic
The subject matter herein provides for a method and apparatus for comparison of network systems using live traffic in real-time. The inventive technique presents real-world workload in real-time with no external impact (i.e. no impact on the system under test), and it enables comparison against a production system for correctness verification. A preferred embodiment of the invention is a testing tool for the pseudo-live testing of CDN content staging servers, According to the invention, traffic between clients and the live production CDN servers is monitored by a simulator device, which then replicates this workload onto a system under test (SUT). The simulator detects divergences between the outputs from the SUT and live production servers, allowing detection of erroneous behavior. To the extent possible, the SUT is completely isolated from the outside world so that errors or crashes by this system do not affect either the CDN customers or the end users. Thus, the SUT does not interact with end users (i.e., their web browsers). Consequently, the simulator serves as a proxy for the clients. By basing its behavior off the packet stream sent between client and the live production system, the simulator can simulate most of the oddities of real-world client behavior, including malformed packets, timeouts, dropped traffic and reset connections, among others. |

Alignment and ordering of vector elements for single instruction multiple data processing
The present invention provides alignment and ordering of vector elements for SIMD processing. In the alignment of vector elements for SIMD processing, one vector is loaded from a memory unit into a first register and another vector is loaded from the memory unit into a second register. The first vector contains a first byte of an aligned vector to be generated. Then, a starting byte specifying the first byte of an aligned vector is determined. Next, a vector is extracted from the first register and the second register beginning from the first bit in the first byte of the first register continuing through the bits in the second register. Finally, the extracted vector is replicated into a third register such that the third register contains a plurality of elements aligned for SIMD processing. In the ordering of vector elements for SIMD processing, a first vector is loaded from a memory unit into a first register and a second vector is loaded from the memory unit into a second register. Then, a subset of elements are selected from the first register and the second register. The elements from the subset are then replicated into the elements in the third register in a particular order suitable for subsequent SIMD vector processing. |

Method and apparatus for indirectly addressed vector load-add-store across multi-processors
A method and apparatus to correctly compute a vector-gather, vector-operate (e.g., vector add), and vector-scatter sequence, particularly when elements of the vector may be redundantly presented, as with indirectly addressed vector operations. For an add operation, one vector register is loaded with the “add-in” values, and another vector register is loaded with address values of “add to” elements to be gathered from memory into a third vector register. If the vector of address values has a plurality of elements that point to the same memory address, the algorithm should add all the “add in” values from elements corresponding to the elements having the duplicated addresses. An indirectly addressed load performs the “gather” operation to load the “add to” values. A vector add operation then adds corresponding elements from the “add in” vector to the “add to” vector. An indirectly addressed store then performs the “scatter” operation to store the results. |

Efficient non-blocking k-compare-single-swap operation
The design of nonblocking linked data structures using single-location synchronization primitives such as compare-and-swap (CAS) is a complex affair that often requires severe restrictions on the way pointers are used. One way to address this problem is to provide stronger synchronization operations, for example, ones that atomically modify one memory location while simultaneously verifying the contents of others. We provide a simple and highly efficient nonblocking implementation of such an operation: an atomic k-word-compare single-swap operation (KCSS). Our implementation is obstruction-free. As a result, it is highly efficient in the uncontended case and relies on contention management mechanisms in the contended cases. It allows linked data structure manipulation without the complexity and restrictions of other solutions. Additionally, as a building block of some implementations of our techniques, we have developed the first nonblocking software implementation of load-linked/store-conditional that does not severely restrict word size. |

Apparatus and method for enabling parallel processing of a computer program using existing database parallelism
An apparatus and method enable parallelism in a computer program using parallelism that is built-in to many modem database managers. The parallelism provided by a database manager in executing user-defined functions provides an easy way to implement parallelism for database and non-database functions in a computer program without the need of hard-coding all the parallelism support in the computer program itself. A database table is defined with instructions the user wants to execute in parallel. A user-defined function is then defined that executes the instructions in the table. A database operation is then defined for the table that invokes the user-defined function. When the database operation is executed, the database manager provides parallelism by executing multiple tasks in parallel in the user-defined function. The built-in parallelism in many modem database managers thus may be used to enable parallelism in a computer program by using user-defined functions in a manner not previously thought of before. |

A computer network packet classification method and system based on a nonoverlapping rule group encoding scheme is proposed, which is designed for integration to a network system for classification of packets within the network system. The proposed method and system is characterized by the use of a nonoverlapping rule group encoding scheme which organizes a database of rules into nonoverlapping rule groups and creates a number of consecutive projected intervals over the dimension of each classification-related field of the packet header, whereby a projected-interval to encoded-bit-vector lookup table and an encoded-bit-vector to rule-group lookup table can be established. During the operation of packet classification, these two lookup tables are used to find the corresponding rule for each incoming packet. This scheme allows the encoded bit vectors to have a reduced bit length, and therefore allows the packet classification to be implemented with low memory requirement and enhanced performance. |

Method and system for full-duplex mesochronous communications and corresponding computer program product
Data transport is provided in a communication network such as a Network-on-Chip arrangement via full-duplex mesochronous links between routers. Request signals and response signals are exchanged between these routers acting alternatively as an initiator and a target operating in respective clock domains at opposite ends of respective full-duplex mesochronous links. The request initiator flow control signals are monitored at the target end of the link while the response target flow control signals are monitored at the initiator end of the link. The monitoring action involves ascertaining if a request has been granted at the initiator end of the link and if a response has been granted at the target end of said link thus correspondingly managing the data flow over the link. |

Pipelined packet switching and queuing architecture
An architecture for a line card in a network routing device is provided. The line card architecture provides a bi-directional interface between the routing device and a network, both receiving packets from the network and transmitting the packets to the network through one or more connecting ports. In both the receive and transmit path, packets processing and routing in a multi-stage, parallel pipeline that can operate on several packets at the same time to determine each packet's routing destination is provided. Once a routing destination determination is made, the line card architecture provides for each received packet to be modified to contain new routing information and additional header data to facilitate packet transmission through the switching fabric. The line card architecture further provides for the use of bandwidth management techniques in order to buffer and enqueue each packet for transmission through the switching fabric to a corresponding destination port. The transmit path of the line card architecture further incorporates additional features for treatment and replication of multicast packets. |

IO latency reduction
An application and audio driver communicate audio data via a ring buffer using a system interface. An application reads or writes data from the buffer in a unit of data. Positions within the buffer correspond to a particular time. To write data to the buffer at a particular position in the buffer that corresponds to a particular time, an application is awaken a period of time (“client-side offset”) before the driver reaches the position. The period of time is computed based on a variety factors. One factor is the amount of time the system interface assumes an application uses to write the unit of data to the buffer. For operations that entail the application inserting data into the buffer, the application may specify a weight value to apply to the factor to reduce it and the latency period. |

Byzantine-fault tolerant self-stabilizing protocol for distributed clock synchronization systems
A rapid Byzantine self-stabilizing clock synchronization protocol that self-stabilizes from any state, tolerates bursts of transient failures, and deterministically converges within a linear convergence time with respect to the self-stabilization period. Upon self-stabilization, all good clocks proceed synchronously. The Byzantine self-stabilizing clock synchronization protocol does not rely on any assumptions about the initial state of the clocks. Furthermore, there is neither a central clock nor an externally generated pulse system. The protocol converges deterministically, is scalable, and self-stabilizes in a short amount of time. The convergence time is linear with respect to the self-stabilization period. |

Optical head capable of providing a subwavelength beams
The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit. |
