Thanks to modern deep learning frameworks that exploit GPUs, convolutional neural networks (CNNs) have been greatly successful in visual recognition tasks. In this paper, we analyze the GPU performance characteristics of five popular deep learning frameworks: Caffe, CNTK, TensorFlow, Theano, and Torch in the perspective of a representative CNN model, AlexNet. Based on the characteristics obtained,...
Histograms are used in various fields to quickly profile the distribution of a large amount of data. However, it is challenging to efficiently utilize abundant parallel resources in modern processors for histogram construction. To make matters worse, the most efficient implementation varies depending on input parameters (e.g., input distribution, number of bins, and data type) or architecture parameters...
