The invention discloses a hash table concurrent access performance optimization method under a multi-core environment. The method comprises the steps that aiming at the concurrent connection treatment of high concurrent access of a hash table, a half-synchronous half-asynchronous network connection treatment mechanism is adopted; aiming at the concurrent data treatment of high concurrent access of the hash table, the hash table is divided into multiple independent sub hash tables according to the number of CPU cores, working threads correspond to the independent sub hash tables in a one-to-one mode, and each working thread is only in charge of the data of the corresponding sub hash table; a main thread selects the corresponding working threads to process by adopting a consistent hash strategy according to the Key of each datum; each sub hash table maintains one LRU queue, when a memory space is insufficient, cold data are deleted, and new elements are inserted. The method improves the concurrent connection treatment capacity and the concurrent access capacity of the hash table, and the synchronization overhead problem and the cache consistency overhead problem are solved when the shared hash table is visited by multiple threads.

The embodiment of the invention relates to a distributed file system access method, a metadata server and a client side. The method comprises the following steps: the metadata server is used for receiving a metadata access request transmitted by the client side; the metadata server is accessed for minimum times in a metadata server cluster; the corresponding metadata is accessed according to the metadata access request; and the accessed frequency of the metadata server in the server domain information stored in all the metadata servers in the metadata server cluster is updated. Through the embodiment of the invention, the uniform load sharing can be realized so as to avoid the situation that when any metadata server become a focus, a plurality of metadata servers are required to be cooperated to process the metadata access request to a certain degree, therefore the operating efficiency is improved, and the processing delay is reduced.

The invention discloses a hot backup method and a hot backup device for a multi-channel power amplifier with an automatic failure detection function and an automatic failure backup function. A plurality of independent channels of the power amplifier are divided into working channels and backup channels; a test signal is added to the input end of each working channel; signal detection units monitor and sample the output end of the power amplifier on each working channel in real time; if the signal detection unit on each working channel can continuously detect the test signal, the power amplifier on the working channel is proved to work normally; and if the signal detection unit on a certain working channel cannot continuously detect a sampling signal, the power amplifier on the working channel is proved not to work normally, and a signal processing and control unit and a switching management unit correspondingly replaces the power amplifier on the failing working channel by the power amplifier on the backup channel to ensure a loudspeaker on the working channel still can work normally.

The invention relates to the technical field of data processing, in particular to a factory-class-based interface message processing method and apparatus, equipment and a storage medium. The factory-class-based interface message processing method comprises the steps: receiving interface messages transmitted by different breakpoint scenes through interfaces, obtaining basic information and specificinformation in the interface messages, and obtaining scene types from the specific information; calling a preset factory class, and analyzing the basic information through a parent class in the factory class to obtain basic data; and mapping a corresponding processing class in the factory class through the scene type, and analyzing the specific information through the processing class to obtain personalized data. According to the invention, the basic information of the interface message in the breakpoint scene is used as a common part, and the specific information is processed by the processing class corresponding to each breakpoint scene, and universal and personalized codes are separated, so that modification, addition and maintenance of personalized codes are facilitated, and the codereadability is high.

The invention provides a port statistical parameter notification method and device. A switch chip on a communication device applying the method identifies a plurality of received parameter remote query messages from a server where a remote processor is located; the exchange chip reads the corresponding statistical parameters according to the register addresses carried by each parameter remote query parameter; the switching chip generates a parameter remote response message for each read statistical parameter; and the switch chip sends each generated parameter remote response message to the server, so that the processor of the server processes all the collected required statistical parameters of the controlled port into structured serialized port statistical data and sends the structured serialized port statistical data to the controller, thereby avoiding occupying a processor processing resource of the communication equipment to read a port statistical parameter register.

The invention discloses a speed analyzing precision improving method in low SNR earthquake data processing, and belongs to the fields of petroleum and natural gas exploration investigation and earthquake data processing. Primary speed analysis is carried out by taking CDP gather data with routine processing, an obtained speed model is used to normal moveout correction on a gather, F-K domain signals in the gather are enhanced after normal moveout correction, the speed model is used to carried out reverse normal moveout correction, an output CDP gather is used to make a speed spectrum and usedfor new speed analysis, and an obtained new speed model is combined with the original CDP gather data to carry out subsequent superposition. Via the method, an energy group of the speed spectrum of speed analysis can be converged relatively, a more accurate speed model is obtained, and the imaging precision of earthquake data is improved. Change of the CDP gather data for speed spectrum preparation does not influence subsequent processing.

The invention provides a service processing method and device. The service processing method comprises the steps that an interface calling instruction is received, and the interface calling instruction comprises a service identifier and an interface identifier; if it is determined that an execution result for the interface calling instruction exists in a result set based on the interface identifier and the service identifier, the execution result is obtained based on the interface identifier and the service identifier and sent to a service platform, and the result set is used for storing the execution result of the logic step of the target interface indicated by the interface identifier. According to the scheme, when the interface calling instruction is received, whether the game server executes the interface calling instruction or not can be judged firstly, if yes, it is indicated that the interface calling instruction is repeatedly sent when the service platform does not receive the execution result, and the stored execution result can be fed back to the service platform; if the service identifier is detected, the to-be-processed service indicated by the service identifier can be continuously executed, so that the processing of the service is not influenced, the influence on other services can be reduced, and the service processing efficiency is further improved.
