Title:

DATA PARALLEL PROCESSING METHOD AND APPARATUS BASED ON MULTIPLE GRAPHIC PROCESING UNITS

Document Type and Number:

WIPO Patent Application WO/2015/192812

Kind Code:

A1

Abstract:

A parallel data processing method based on multiple graphic processing units (GPUs) is provided, including: creating, in a central processing unit (CPU), aplurality ofworker threads for controlling a plurality ofworker groups respectively, the worker groups including one or more GPUs; binding each worker thread to a corresponding GPU; loading a plurality ofbatches of training data from a nonvolatile memory to GPU video memories in the plurality ofworker groups; andcontrolling the plurality of GPUs to perform data processing in parallel through the worker threads. The method can enhance efficiency ofmulti-GPU parallel data processing. In addition, a parallel data processing apparatus is further provided.
