[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0019] An AllReduce-based distributed training gradient compression acceleration method provided by an embodiment of the present invention. The following is a detailed explanation.
[0020] figure 1 It is a distributed deep gradient compression training architecture with Params Server (PS) structure, figure 2 It is an AllReduce-based distributed deep gradient compression training framework according to the embodiment of the present invention. Among them, the GPUs of each machine in the PS architecture form a closed loop to transmit the gradient after Intra-node compression; there is no communication connection between the working machines, and the gradient after inter-node compression is transmitted between the w...
