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 ./bootstrap ./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.
