Build a PBS compute cluster

Visualisation: config.json

This example will create an HPC cluster ready to run with PBS Pro.

Initialise the project

To start you need to copy this directory and update the config.json. Azurehpc provides the azhpc-init command that can help here by compying the directory and substituting the unset variables. First run with the -s parameter to see which variables need to be set:

azhpc-init -c $azhpc_dir/examples/simple_hpc_pbs -d simple_hpc_pbs -s

The variables can be set with the -v option where variables are comma separated. The output from the previous command as a starting point. The -d option is required and will create a new directory name for you. Please update to whatever resource_group you would like to deploy to:

azhpc-init -c $azhpc_dir/examples/simple_hpc_pbs -d simple_hpc_pbs -v resource_group=azurehpc-cluster

Note: You can still update variables even if they are already set. For example, in the command below we change the region to westus2 and the SKU to Standard_HC44rs:

azhpc-init -c $azhpc_dir/examples/simple_hpc_pbs -d simple_hpc_pbs -v location=westus2,vm_type=Standard_HC44rs,resource_group=azhpc-cluster

Create the cluster

cd simple_hpc_pbs
azhpc-build

Allow ~10 minutes for deployment. You are able to view the status VMs being deployed by running azhpc-status in another terminal.

Log in the cluster

Connect to the headnode and check PBS and NFS

$ azhpc-connect -u hpcuser headnode

To check the state of the cluster you can run the following commands

azhpc-connect -u hpcuser headnode
qstat -Q
pbsnodes -avS
df -h
