You can use the following instructions to install Theano and configure the GPU (assume a freshly installed Ubuntu 14.04):
# Install Theano
sudo apt-get install python-numpy python-scipy python-dev python-pip python-nose g++ libopenblas-dev git
sudo pip install Theano
# Install Nvidia drivers, ...
You can run Theano on multiple CPU cores with the OMP_NUM_THREADS=[number_of_cpu_cores] flag.
Example:
OMP_NUM_THREADS=4 python gpu_test.py
The script theano/misc/check_blas.py outputs information regarding which BLAS is used:
cd [theano_git_directory]
OMP_NUM_THREADS=4 python theano/misc/ch...
