摘要： An optical signal receiver tracks local oscillator frequency offset (LOFO) and compensates for the phase distortion introduced in the received signals as a result of utilizing the local oscillator within a coherent detection scheme. This phase distortion is basically a constant phase rotation caused by the LOFO and implementation of the receiver using coherent detection and a digital interferometer instead of a conventional (yet complex) carrier phase estimation or recovery scheme. With an optical receiver implemented in this manner, the requirement of using a precise local oscillator laser with low frequency offset is less important.
摘要翻译：光信号接收器跟踪本地振荡器频率偏移（LOFO），并且通过在相干检测方案中利用本地振荡器来补偿在接收信号中引入的相位失真。该相位失真基本上是由LOFO引起的恒定相位旋转和使用相干检测的接收机的实现以及数字干涉仪而不是常规（但复杂的）载波相位估计或恢复方案。通过以这种方式实现的光接收机，使用具有低频偏移的精确本地振荡器激光器的要求不那么重要。

摘要： A data processing method and apparatus, and a system are provided. The system to which the method is applicable includes a central processing unit (Central Processing Unit, CPU for short) pool and a storage pool, a mapper node and a reducer node respectively run on different CPUs in the CPU pool, and a remote shared partition shared by the mapper node and the reducer node is delimited in the storage pool. In this method, the mapper node executes a map task, and stores a data segment obtained by executing the map task, into the remote shared partition; and the reducer node directly obtains a data segment to be processed by the reducer node from the remote shared partition, and executes a reduce task on the data segment. The method omits some actions in the prior art, and shortens a time for executing the Map/Reduce task. The omitted actions include: writing, by the mapper node, the data segment into a local disk by using a disk input/output (Input/Output, I/O for short), and when the reducer node requests the data segment, reading the data segment from the local disk by using the disk I/O.

摘要： Embodiments of the present invention provide a method and apparatus for system call command batch processing and relate to the computer field. The method and apparatus for system call command batch processing enable system call commands of a same type to be processed in a same CPU core according to a sequence of entering a kernel, thereby ensuring that returned results of the system call commands are sequential. The method for system call command batch processing includes: obtaining multiple system call commands, where the multiple system call commands are commands that need to call a kernel function; classifying the multiple system call commands according to task identifiers of the multiple system call commands, where system call commands of a same type have a same task identifier; and sending, according to a sequence of obtaining the multiple system call commands, system call commands of a same type to a same CPU core for processing.
