Abstract: An encapsulation structure of a power module is disclosed in this application, which includes a power module and a liquid cooler. The power module includes a power module body, a metal baseplate, and heat dissipation finned tubes. A front side of the metal baseplate is connected to the power module body, and a back side of the metal baseplate is connected to the heat dissipation finned tubes. The metal baseplate has a protrusion part protruding. There are a plurality of grooves on a fluid pipe of the liquid cooler, a cavity exists between two adjacent grooves of the plurality of grooves, and the cavity is configured to communicate the two adjacent grooves. The power module body is lapped on the groove, a back side of the protrusion part is in contact with an edge surface of the groove, and the heat dissipation finned tubes are placed in the groove.

Abstract: A data processing method and apparatus are provided. A system includes a 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 storage area 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 storage area; and the reducer node directly obtains a data segment to be processed by the reducer node from the remote storage area, 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.

Abstract: A method and an apparatus for detecting a transaction conflict and a computer system are provided. The method is applied to a computer system whose memory is a non-volatile memory, where the memory includes at least two memory areas. The at least two memory areas have different detection policies. According to the method, a memory controller receives addresses in at least two operation instructions of a first transaction. Then, the memory controller executes, according to a first detection policy of a first memory area, conflict detection on at least one operation instruction that is to access the first memory area, and executes, according to a second detection policy of a second memory area, conflict detection on at least one operation instruction that is to access the second memory area, so as to obtain a conflict detection result of the first transaction.
