project background
Deep learning, especially convolutional neural networks (CNN) and graph neural networks (GNN), has become basic technologies in modern computer vision, natural language processing, recommendation systems and other fields. As the scale of deep learning models continues to expand, traditional computing methods are facing computing bottlenecks. Especially when the size of the data set gradually increases, processing power often becomes a bottleneck that restricts the efficiency of the algorithm. Therefore, developing efficient parallel computing frameworks, especially frameworks that can efficiently utilize GPU acceleration, is crucial to advancing the research and application of deep learning.
As a leader in the field of artificial intelligence hardware and software, NVIDIA raised the need for efficient model training and data processing years ago, and the Sana project was designed for this. By combining deep learning architecture with GPU-accelerated hardware, Sana provides an efficient way to train and optimize large-scale machine learning models.
