Abstract: A mapper node and a reducer node respectively run on different central processing units (CPUs) in a CPU pool, and a remote shared partition shared by the mapper node and the reducer node is delimited in the storage pool. The mapper node executes a map task to obtain a data segment, and stores the data segment into a remote shared partition. The reducer node directly obtains a to-be-processed data segment from the remote shared partition, and executes a reduce task on the to-be-processed data segment.

Abstract: A communications system and a communication method are disclosed. The communication method includes: sending, by a first computing node, a communication manner parsing request to a management node, where the communication manner parsing request includes an identifier of the first computing node and an identifier of a second computing node; determining, by the management node, information about a physical communication manner between the first computing node and the second computing node according to the communication manner parsing request and communication manner reference information, where the communication manner reference information includes system topology information and a system physical resource allocation result; sending, by the management node, the information about the physical communication manner to the first computing node; and communicating, by the first computing node, with the second computing node based on the information about the physical communication manner.

Abstract: A data processing method and apparatus, and a system, where the method applies to a system including a central processing unit (CPU) 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. Hence, the method shortens a time for executing the Map/Reduce task.

Abstract: A data distribution method and a splitter is provided. The data distribution method executed by the splitter includes: parsing a received data packet to determine a transport layer communications protocol to which the data packet belongs; acquiring from the data packet, identification information of a data stream to which the received data packet belongs; acquiring from a memory according to a correspondence between a transport layer communications protocol and an distribution table, an distribution table corresponding to the transport layer communications protocol to which the data packet belongs; determining according to a correspondence between identification information of a data stream and a thread in the acquired distribution table, a thread corresponding to the data stream to which the data packet belongs; and sending the data packet to a cache queue of the determined thread, so that the determined thread acquires the data packet from the cache queue.
