-## 4. Compiling the application
-The QE-GPU gives more details but for the benchmark suite we followed
-this general procedure: 
+## 4. Compiling and installing the application
 
-1. Uncompress the main QE distribution and copy the GPU source distribution inside:
+This distribution does not have a ```configure``` command. Instead you make
+changes directly in the ```make.inc``` file.
 
-``` shell
-tar zxvf espresso-5.4.0.tar.gz
-cp 5.4.0.tar.gz espresso-5.4.0`
-```
-2. Uncompress the GPU source inside main distribution and create a symbolic link:
-
-``` shell
-cd espresso-5.4.0
-tar zxvf 5.4.0.tar.gz
-ln -s QE-GPU-5.4.0 GPU`
-```
-
-3. Run QE-GPU configure and make:
-
-``` shell
-cd  GPU
-./configure --enable-parallel --enable-openmp --with-scalapack=intel \
-  --enable-cuda --with-gpu-arch=Kepler \
-  --with-cuda-dir=/usr/local/cuda/7.0.1 \
-  --without-magma --with-phigemm
-cd ..
 make -f Makefile.gpu pw-gpu
 ```
