Abstract

The invention provides a data distributed operation method and device, a storage medium and a processor, wherein the method comprises the steps of enabling a single-machine script submitted by a userto generate a directed acyclic graph DAG, wherein the DAG comprises a plurality of operation instances OPs; splitting the OP according to the generated DAG, the GPU resource request submitted by the user and the system GPU resource to obtain a plurality of sub-OPs; placing the plurality of sub-OPs on different computing nodes according to the computing loss of each sub-OP to divide the plurality of sub-OPs into a plurality of layers, and running the sub-OPs on the computing nodes of the plurality of layers in parallel, wherein the calculation loss of the sub-OP of the current layer is smallerthan the calculation loss of other sub-OPs on the current layer. Through the present invention, the problem that the specific equipment cannot be specified in the codes due to dynamic distribution ofthe equipment when a user writes the distributed codes in a large-scale cloud environment in the prior art is solved, and the algorithm efficiency of the system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data distributed operation method and device, a storage medium and a processor. Background technique [0002] Artificial intelligence is one of the most cutting-edge technologies in the 21st century, and deep learning is the most effective and effective implementation method to realize artificial intelligence, and it is the hottest branch of machine learning at present. [0003] The model training of deep learning algorithms places extremely high demands on computing power. For example, FaceNet, a face model developed by Google, contains 140 million parameters, and one inference will cost 1.6 billion floating-point operations. In order to improve computing power, one is to increase single-point computing power, such as using hardware such as Graphic Processing Unit (GPU for short), Field Programmable Gate Array (Field Programmable Gate Array, FPGA for short) to accelerate com...
