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. |

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. |

Since data storage, data input, and data sense are integrated into one cell, the memory combines higher densities with non-volatility. The memory can support high speed, reduced power consumption, and data masking. |
