d. Install IOR Benchmark Tool

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.

To install IOR from source, use the following commands. For this installation, we use the io500-sc19 branch of the repository on the cluster head node.

# get IOR
mkdir -p /shared/ior
git clone https://github.com/hpc/ior.git
cd ior
git checkout io500-sc19

# load intelmpi
module load intelmpi

# install
./configure --with-mpiio --prefix=/shared/ior
make -j 10
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.
