Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for memory mapping to enhance data cube performance. In some implementations, a system accesses a data set that includes data to be processed into a data cube. The system generates a memory-mapped data cube that includes a plurality of files including different segments of the data cube. Generating the memory-mapped data cube includes allocating memory-mapped buffers in non-volatile data storage and responding to subsequent memory allocation requests with addresses for the buffers such that components of the data cube are accumulated in the buffers. The memory-mapped data cube is loaded by storing the files of the data cube in disk-based storage, mapping the stored files of the data cube to virtual memory addresses, and caching portions of the data cube in random-access memory.

Abstract: The present invention provides a method for accessing a wireless network, so as to implement acquisition of system synchronization during the process of accessing the wireless network in the situation that a physical frame structure can be configured dynamically. The method for acquiring system synchronization comprises: searching a physical frame on a current sub-channel; resolving a system information channel (SICH) and a control channel (CCH) in the found physical frame, wherein the SICH indicates a structure of the physical frame, and the CCH indicates allocation of system resources; and acquiring a system parameter from the physical frame by using the resolving result. A device for implementing the above method is further provided.

Abstract: In the present invention, before data transmission, a “connection”, between a requesting end and a destination end, identified by a traffic flow identifier (FID) is established or modified through traffic flow management. Therefore, when the requesting end and the destination end perform data transmission on the traffic flow, the FID alone can sufficiently serve as the identifier, so as to save the need of carrying the destination end identifier in each exchanged data packet, thereby simplifying the operation.
