FIO

Fio is a general I/O benchmark code, it has many options to configure and customize the I/O pattern being tested.

To build a cluster with PBS, see one of the examples, e.g. simple_hpc_pbs

Copy the apps directory to the cluster.

    azhpc-scp -r $azhpc_dir/apps hpcuser@headnode:.

Connect to the headnode

    azhpc-connect headnode

Build fio from the build script. This will build and install it in /apps/fio and create a modulefile.

    build_fio.sh

Now submit and run:

     qsub -l select=1:ncpus=60:mpiprocs=8 fio.pbs

Note: this will run on 1 node, 8 fio processes (fio numjobs). Fio can run on multiple nodes in a client-server mode, this example is designed to run on a single node. You can change the fio numjobs parameter (i.e number of processes) by changing the PBS mpiprocs value. A throughput and IOPS benchmark will be run.

A similar script is provided to run the same fio benchmark (throughput and IOPS) on a Windows client.

A Windows fio executable can be downloaded from

    https://bsdio.com/fio/

Run the windows_fio.ps1 powershell script from a Windows powershell prompt.

    windows_fio.ps1

Note: You may need to modify the DIRECTORY and ALLJOBS variables in the windows_fio.ps1 script to reflect the location of the drive you want to test and the number of jobs wou want to run on the windows client.
