    • A parallel processing method involves the steps of determining a sequential ordering of tasks for processing, assigning priorities to available tasks on the basis of the earliest and then later in the sequential ordering, selecting a number of tasks greater than a total number of available parallel processing elements from all available tasks having the highest priorities, partitioning the selected tasks into a number of groups equal to the available number of parallel processing elements, and executing the tasks in the groups in the parallel processing elements. The determining step establishes an ordering with a specific predetermined sequential schedule that is independent of the parallel execution, and the assigning step assigns priorities for parallel execution on the basis of the sequential schedule that is independent of the parallel execution.
    • 并行处理方法包括以下步骤:确定用于处理的任务的顺序排序,基于顺序排序中的最早然后稍后的顺序为可用任务分配优先级,选择大于总数的可用并行处理 来自具有最高优先级的所有可用任务的元素,将所选择的任务划分成等于可用数量的并行处理元素的多个组,以及在并行处理元素中执行组中的任务。 确定步骤建立具有独立于并行执行的特定预定顺序调度的排序,并且分配步骤基于独立于并行执行的顺序调度分配用于并行执行的优先级。

    • A data compression technique for encoding a data stream of symbols processes a current sequence of symbols in the stream using an adaptive look-up table containing strings of different lengths by identifying whether a match of a longest string from the table or a shorter string would produce a lower compression ratio by "looking ahead" and identifying a match between a next sequence in the data stream and strings in the table. The compression technique identifies those situations where it is advantageous to use a compressed code identifier for a current sequence that is shorter than the longest matching sequence. Such situations exist when the compression ratio achieved for compressing the current sequence in combination with the next sequence in the stream is greater when other than the longest match is employed for the first sequence. A corresponding decompression technique to decode data encoded using a similar "look ahead" technique is also disclosed.
    • 用于编码符号的数据流的数据压缩技术使用包含不同长度字符串的自适应查找表来处理流中的当前符号序列,通过识别来自表或较短字符串的最长字符串的匹配是否会产生 通过“向前看”并且识别数据流中的下一个序列和表中的字符串之间的匹配来降低压缩比。 压缩技术识别那些使用比最长匹配序列短的当前序列的压缩代码标识符是有利的情况。 当对于第一序列采用除最长匹配之外的当压缩当前序列与流中的下一个序列相结合的压缩比时,存在这种情况。 还公开了对使用类似的“前瞻性”技术编码的数据进行解码的对应的解压缩技术。

    • Methods, apparatus and computer readable code for compression, encoding and decoding of units of data such as packets are disclosed. In some embodiments, methods, apparatus and computer readable code for transmitting and/or receiving the data packets (for example, transmitting from a sending location to a receiving location where packets are received) are provided. For at least some packets, a dictionary is determined from a respective group of packets, including a first set of historical packets and excluding a second set of historical packet. Each target packet is encoded and/or compressed and/or decoded using the respective dictionary. Optionally, the respective group of packet includes the actual target packet to be encoded and/or compressed and/or decoded. In some embodiments, respective group of packets from which the dictionary is determined includes packets that have not been acknowledged from the receiving location at the time of encoding, though embodiments where packets have been acknowledged are also disclosed.
