Abstract

The invention provides a hybrid parallel computing method and a device for CPUs / GPUs. The method comprises following steps of utilizing more than one computing nodes to establish a computing cluster and determining a scheduling policy based on the fact that each computing node comprises a CPU and a GPU; acquiring more than one waiting task; caching more than one acquired waiting task to a task queue; scheduling more than one waiting task to more than one computing node in the task queue; pre-processing scheduled waiting tasks one by one by the CPUs in computing nodes scheduled with waiting tasks and mapping pre-processed tasks to video memory of the GPUs every time when one task is pre-processed; computing tasks mapped to video memory by the GPUs and returning computed results. According to the scheme, computing efficiency of the computing nodes is increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a CPU / GPU hybrid parallel computing method and device. Background technique [0002] With the rapid development of computer technology, the level of data processing is also increasing. In order to solve the increasingly urgent problem of big data processing, the MapReduce programming model has been proposed. MapReduce is a distributed programming model, which can conveniently distribute massive data sets to each node of the computing cluster, so that multiple nodes can jointly process , so as to realize the rapid processing of big data. [0003] In order to further improve the computing performance of MapReduce, academia and industry have made many related researches. The emergence of a single-core GPU (Graphics Processing Unit, graphics processing unit) has brought a huge effect to the performance improvement of the system. Among them, the GPU contains hundreds of stream pro...
