### Compile with MASS Support on Power CPU (Optional dependency)
[IBM MASS](http://www-01.ibm.com/software/awdtools/mass/linux/mass-linux.html) library consists of a set of mathematical functions for C, C++, and
Fortran-language applications that are tuned for optimum performance on POWER architectures. OpenBLAS with MASS requires 64-bit, little-endian OS on POWER.
The library can be installed as below -
* On Ubuntu:
wget -q http://public.dhe.ibm.com/software/server/POWER/Linux/xl-compiler/eval/ppc64le/ubuntu/public.gpg -O- | sudo apt-key add -
echo "deb http://public.dhe.ibm.com/software/server/POWER/Linux/xl-compiler/eval/ppc64le/ubuntu/ trusty main" | sudo tee /etc/apt/sources.list.d/ibm-xl-compiler-eval.list
sudo apt-get update
sudo apt-get install libxlmass-devel.8.1.3
* On RHEL/CentOS:
wget http://public.dhe.ibm.com/software/server/POWER/Linux/xl-compiler/eval/ppc64le/rhel7/repodata/repomd.xml.key
sudo rpm --import repomd.xml.key
wget http://public.dhe.ibm.com/software/server/POWER/Linux/xl-compiler/eval/ppc64le/rhel7/ibm-xl-compiler-eval.repo
sudo cp ibm-xl-compiler-eval.repo /etc/yum.repos.d/
sudo yum install libxlmass-devel.8.1.3
After installing MASS library, compile openblas with USE_MASS=1.
Example:
Compiling on Power8 with MASS support -
make USE_MASS=1 TARGET=POWER8
### Install to the directory (optional)
