Problems solved by technology

[0006] When the one-dimensional chip chain includes a large number of chips, the Broadcast and Gather messages need to be transmitted from one end of the one-dimensional chip chain to the other in turn, and need to be forwarded by more chips, requiring a longer message transmission time, thereby improving Reduce the data processing delay of DNN and reduce the data processing efficiency of DNN

Abstract

An embodiment of the invention provides a data processing device and a server. The data processing device comprises M rows of node chips, each row of node chips include N node chips, first node chips in the M rows of node chips are sequentially connected to form begin column node chips, wherein M and N are integers larger than 1, each first node chip in the begin column node chips is used for sequentially transmitting and processing first communication data according to the sequence from a first row to an M row, each node chip in each row of node chips is used for sequentially transmitting and processing the first communication data according to the sequence from a first node chip to a last node chip. According to the data processing device, transmission time of the communication data can be shortened, and processing efficiency of data is improved.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data processing device and server. Background technique [0002] At present, deep learning is a new field in machine learning research, and it is one of the hottest fields in all high-tech research and development. Its motivation is to establish and simulate the neural network of human brain for analysis and learning. Mechanisms to interpret data such as images, sounds, and text. [0003] The key to deep learning is DNN (Deep Neural Network, deep neural network). Since DNN has a deep structure and tens of millions of parameters need to be learned, the prediction and training process of DNN requires huge computing power. Usually, DNN is formed by computing nodes deployed on multiple chips to improve the computing power of DNN. [0004] During the DNN training process, it is often necessary to transmit Broadcast (broadcast) messages and Gather (collection) messages between the CPU ...
