Must do!!! Use node before running anything on NNhome

To run GUNDAM on GPU should be used:

srun --gres=gpu --mem=30GB --pty bash -i

Otherwise:

srun --nodelist=birch --pty bash -i
#Run an interactive terminal on a particular node."birch" in this example. 
#Available Nodes: "birch", "aspen", "fir", "cedar"

Environment Set Up

Set up your environment. On this cluster, you only need to source ROOT. You can either install and source your own version or use the already installed version.:

source /home/riccioc/root/6.32.02/root_install/bin/thisroot.sh

Building Gundam

As for the general guide we propose to compile the software with this tree directory:

export WORK_DIR="$HOME/Work"
export INSTALL_DIR="$WORK_DIR/Install/"
export BUILD_DIR="$WORK_DIR/Build/"
export REPO_DIR="$WORK_DIR/Repositories/"

Then create these path:

mkdir -p $INSTALL_DIR
mkdir -p $BUILD_DIR
mkdir -p $REPO_DIR

Let’s clone Gundam with git:

cd $REPO_DIR
git clone --recurse-submodules https://github.com/gundam-organization/gundam.git
cd gundam
git submodule sync
git submodule update --init

Now let’s build the thing:

mkdir -p $BUILD_DIR/gundam
mkdir -p $INSTALL_DIR/gundam

cmake \
-D CMAKE_INSTALL_PREFIX:PATH=$INSTALL_DIR/gundam \
-D CMAKE_BUILD_TYPE=Release \
$REPO_DIR/gundam/.

make install -j4

In principle in should be compiling fine… Or this guide is failing to do his job!! Please report any issue!

Once the software is installed, let’s link the bin and lib folders:

export PATH="$INSTALL_DIR/gundam/bin:$PATH"
export LD_LIBRARY_PATH="$INSTALL_DIR/gundam/lib:$LD_LIBRARY_PATH"

Now you should be able to run your first gundam command:

gundamFitter

The program should stop while complaining that you didn’t provide a config file:

Congrats! Now gundam is installed on your cluster! :-D
