Install the platform¶

The COMPASS platform is distributed as a single bundle of CArMA and SuTrA libraries and YoGA and its AO extension for Yorick.

Hardware requirements¶

The system must contain at least an x86 CPU and a CUDA capable GPU. list of compatible GPUs can be found here (). Specific requirements apply to clusters (to be updated).

Environment requirements¶

The system must be running a 64 bit distribution of Linux or Mac OS with the latest NVIDIA drivers and CUDA toolkit.

Additionally, to benefit from the user-oriented features of the platform, Yorick should be installed as well as the latest version of Python and the associated pygtk module.

To install Yorick, download the latest version from the github repository:

git clone https://github.com/dhmunro/yorick.git yorick.git

then cd onto the created directory and install:

./configure && make && make install

once Yorick is locally installed, you will have to add this directory : yorick.git/relocate/bin to your PATH to have an easy access to the yorick executable. You may want to add support for command history by using rlwrap and alias the yorick executable as :

alias yorick='rlwrap path_to_yorick_executable/yorick'

Installation process¶

First check out the latest version from the svn repository :

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

then go in the newly created directory and then trunk:

cd compass/trunk

once there, you need to modify system variables in the define_var.sh executable :

emacs define_var.sh

in this file define properly CUDA_ROOT, CULA_ROOT and YoGA path. Note that for the latter, as YoGA is distributed with SUTrA you should just point to the newly created trunk directory. On a Linux system you should normally have:

export CUDA_ROOT=/usr/local/cuda
export CULA_ROOT=/usr/local/cula
export YOGA_DIR=/home/MyUserName/path2compass/trunk

Once this is done, you're ready to compile the whole library. First run define_var.sh to define the system variables that will be used during the compilation process:

./define_var.sh

then identify the absolute path to your Yorick executable using:

which yorick

and run the compilation script:

./reinstall absolute_path_to_yorick

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

yorick -i yoga_ao/ywidgets/widget_ao.i
