Install MAGMA¶

Why MAGMA ?¶

The MAGMA project aims to develop a dense linear algebra library similar to LAPACK but for heterogeneous/hybrid architectures, starting with current "Multicore+GPU" systems.

Unlike CULA, MAGMA propose a dense linear algebra library handling double for free.

But MAGMA needs a LAPACK and a BLAS implementation. Actually, we try two options : openBLAS (free, easy to install) and MKL (free, need a registration but better optimized on Intel processors)

Dependencies : gfortran¶

Use your package manager to install dependencies:

• on scientific linux : yum install gcc-gfortran libgfortran
• on debian : apt-get install gfortran gfortran-multilib

Configure MAGMA with openBLAS¶

Dependencies : openblas (http://www.openblas.net)¶

First, clone the GIT repository:

git clone https://github.com/xianyi/OpenBLAS.git

compile it:

cd OpenBLAS/
make

install it:

sudo make install PREFIX=/usr/local/openblas-haswellp-r0.2.14.a

add to you .bashrc:

export OPENBLAS_ROOT=/usr/local/openblas-haswellp-r0.2.14.a

extraction¶

MAGMA is available here : http://icl.cs.utk.edu/magma/software/index.html

extract the tgz file and go into the new directory

_{$ tar xf magma-1.7.0-b.tar.gz}
$ cd magma-1.7.0

configuration¶

You have to create your own make.inc based on make.inc.openblas:

example : please verify GPU_TARGET, OPENBLASDIR, CUDADIR

Configure MAGMA with MKL¶

extraction¶

To download MKL, you have to create a account here : https://registrationcenter.intel.com/RegCenter/NComForm.aspx?ProductID=1517

extract l_ccompxe_2013_sp1.1.106.tgz and go into l_ccompxe_2013_sp1.1.106

install it with ./install_GUI.sh and add IPP stuff to default choices

INC       = -I$(CUDADIR)/include \
            -I$(MKLROOT)/include

In this example, I use gcc but with MKL, you can use icc instead of gcc. In this case, you have to compile yorick with icc. For this, you have to change the CC flag in Make.cfg

compilation and installation¶

compilation¶

just compile the shared target (and test if you want)

~$ make -j 8 shared sparse

installation¶

To install libraries and include files in a given prefix, run:

~$ make install prefix=/usr/local/magma

The default prefix is /usr/local/magma. You can also set prefix in make.inc.

tuning (not tested)¶

For multi-GPU functions, set $MAGMA_NUM_GPUS to set the number of GPUs to use.
For multi-core BLAS libraries, set $OMP_NUM_THREADS or $MKL_NUM_THREADS or $VECLIB_MAXIMUM_THREADS to set the number of CPU threads, depending on your BLAS library.

Install the platform¶

The COMPASS platform is distributed as a single bundle of CArMA and SuTrA C++ / Cuda libraries and their Python extensions NAGA & SHESHA.

Hardware requirements¶

The system must contain at least an x86 CPU and a CUDA capable GPU. list of compatible GPUs can be found here http://www.nvidia.com/object/cuda_gpus.html. Specific requirements apply to clusters (to be updated).

Environment requirements¶

The system must be running a 64 bit distribution of Linux with the latest NVIDIA drivers and CUDA toolkit. The following installation instructions are valid if the default installation paths have been selected for these components.

Additionally, to benefit from the user-oriented features of the platform, Anaconda should be installed.
In the last versions of compass (r608+), Yorick is no more supported.

For the widget, you also need pyQTgraph. You can install it like this :

pip install pyqtgraph 

Installation process¶

First check out the latest version from the svn repository :

svn co https://version-lesia.obspm.fr/repos/compass/trunk compass

then go in the newly created directory and then trunk:

cd compass

once there, you need to modify system variables in our .bashrc :

# CUDA default definitions
export CUDA_ROOT=$CUDA_ROOT #/usr/local/cuda
export CUDA_INC_PATH=$CUDA_ROOT/include
export CUDA_LIB_PATH=$CUDA_ROOT/lib
export CUDA_LIB_PATH_64=$CUDA_ROOT/lib64
export PATH=$CUDA_ROOT/bin:$PATH

in this file, you also have to indicate the proper architecture of your GPU so as the compiler will generate the appropriate code.

export GENCODE="arch=compute_52,code=sm_52" 

and change both 52 to your architecture : for instance a Tesla Fermi will have 2.0 computing capabilities so change 52 to 20, a Kepler GPU will have 3.0 or 3.5 (K20) computing capabilities, change 52 to 30 (or 35), a Maxwell GPU have 5.2 (M6000).

If you are using CULA, you have to specify it:

# CULA default definitions
export CULA_ROOT= /usr/local/cula
export CULA_INC_PATH= $CULA_ROOT/include
export CULA_LIB_PATH= $CULA_ROOT/lib
export CULA_LIB_PATH_64= $CULA_ROOT/lib64

If you are using MAGMA, you have to specify it:

# MAGMA definitions (uncomment this line if MAGMA is installed)
export MAGMA_ROOT=/usr/local/magma
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$MAGMA_ROOT/lib
export PKG_CONFIG_PATH=$MAGMA_ROOT/lib/pkgconfig

Last variables to define:

export COMPASS_ROOT=/path/to/compass/trunk
export NAGA_ROOT=$COMPASS_ROOT/naga
export SHESHA_ROOT=$COMPASS_ROOT/shesha
export LD_LIBRARY_PATH=$COMPASS_ROOT/libcarma:$COMPASS_ROOT/libsutra:$CUDA_LIB_PATH_64:$CUDA_LIB_PATH:$CULA_LIB_PATH_64:$CULA_LIB_PATH:$LD_LIBRARY_PATH

Once this is done, you're ready to compile the whole library:

make clean install

If you did not get any error, CArMA, SuTrA, NAGA and SHESHA are now installed on your machine. You can check that everything is working by launching a GUI to test a simulation:

cd $SHESHA_ROOT/widgets && ipython -i widget_ao.py
