CNNG is a progression of neural systems that work cooperatively to deal with various errands independently in a similar learning framework.

Bandwidth Reduction using Importance Weighted Pruning on Ring AllReduce

no code implementations6 Jan 2019 Zehua Cheng, Zhenghua Xu

In order to save more communication bandwidth and preserve the accuracy on ring structure, which break the restrict as the node increase, we propose a new algorithm to measure the importance of gradients on large-scale cluster implementing ring all-reduce based on the size of the ratio of parameter calculation gradient to parameter value.
