Installing Torch locally

Load necessary modules (probably just add these lines to your ~/.bashrc):

module load gcc-4.9
module load OpenBLAS
module load fbcunn
module load cuda-7.0

export CC=gcc
export CXX=g++

SSH into a GPU machine, then clone torch and install it:

ssh rose2 # for example
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch && ./install.sh

Troubleshooting

Important: If you have already run ./install.sh, you need to run ./clean.sh before you try installing again. Otherwise the install script will still be using whichever compilers and stuff were in your path the first time you tried to install.

Use the right machines

Make sure you're in a machine that supports CUDA before you try to load cunn or cutorch! When you run nvidia-smi, you should see something like this:

If instead you see something like this, use a different machine:
