You can conduct performance tests on your Lustre partition to evaluate the throughput it provides. To do so, you must first install IOR, an IO parallel benchmark tool used to test the performance of a parallel file system.
Use the following command to get, configure, compile and install IOR. For this installation, use the 4.0 branch of the repository on the cluster head node.
# get IOR
mkdir -p /shared/ior
cd /shared/ior
git clone https://github.com/hpc/ior.git
cd ior
git checkout 4.0
# load intelmpi
module load intelmpi
# bootstrap, configure, compile and install IOR
./bootstrap
./configure --with-mpiio --prefix=/shared/ior
make -j 8
sudo make install
# set the environment
export PATH=$PATH:/shared/ior/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/shared/ior/lib
echo 'export PATH=$PATH:/shared/ior/bin' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/shared/ior/lib' >> ~/.bashrc
Now, you are ready to do some performance testing.
