# Is NVIDIA SLI (Scalable Link Interface) used in Deep Learning?

## post by mpb on Jul 5, 2018

No.

NVIDIA SLI is used for distributing graphics rasterization across multiple GPUs. SLI cannot be used to achieve performance gains in Machine Learning / Deep Learning applications. All machine learning libraries (e.g. TensorFlow, PyTorch, and Caffe) interface with the GPU through CUDA, which has no concept of SLI.
