Contents of Torch

This container image contains the complete source of the version of NVIDIA Torch in /opt/torch. It is pre-built and installed into the /usr/local/[bin,share,lib] directories in the container image.

The NVIDIA^® Collective Communications Library ™ (NCCL) (NCCL) library and Torch bindings for NCCL are installed in this container, and models using DataParallelTable can easily leverage this library for fast parallel training. The container also includes the following:

• Ubuntu 14.04
• NVIDIA CUDA 8.0.54
• NVIDIA CUDA^® Deep Neural Network library™ (cuDNN) 6.0.5
• NVIDIA NCCL 1.6.1 (optimized for NVLink™ )
