This project is aimed at simplifiying deployment and setup for HPC environments in Azure. The deployment scripts include setting up various building blocks available for Networking, Compute and Storage that are needed for an e2e setup. You can do this all with a few commands and fast as these are run in parallel.
They key motivation is:
- Simplified Automation
- Flexibility
- Speed of deployment
The basis for the project is a single JSON config file and some shell scripts for installing. The key point about the config file is that you can describe network, resources and installation steps. Tags are applied to resources that determines which resources run each install step.
The azhpc_*
scripts only require the azure cli and a few utilities (bash, jq and ssh).
All of this is available in the Cloud Shell. Alternatively you can run on a Linux VM on Azure or from the Windows Ubuntu Shell.
Multiple examples for building blocks commonly used, scripts for building, installing and running some applications are included here so they can be used as you build your environment and run benchmarks.
We have also made some tutorials available that you can follow to not only learn more about the framework but also to understand how you can easily set an environment up e2e for your own application.
The JSON file is composed of the following:
- Variables dictionary
- Setup information
- Network dictionary
- Storage dictionary
- Resources dictionary
- Install list
- CycleCloud dictionary
Note : for the full config structure file see config.json
This allows variables to be created and used throughout the config file (see how this works here. This can be used when creating a template for others to use or just when the same value is repeated for many resources, e.g. choosing the OS image.
When creating templates for others to use the value should be
<NOT-SET>
so theazhpc-*
commands will notify the user.
To allow a better reuse of variables across several configuration files the variable section can reference a file like this :
{
"variables": "@variables.json"
}
The referenced file should contains variables this way :
{
"image": "OpenLogic:CentOS:7.7:latest",
"hpc_image": "OpenLogic:CentOS-HPC:7.7:latest",
"location": "westeurope",
"resource_group": "my resource group",
"vm_type": "Standard_HB60rs",
"vnet_resource_group": "variables.resource_group",
}
The following properties are global :
Name | Description | Required | Default |
---|---|---|---|
location | The region where the resources are created | yes | |
resource_group | The resource group to put the resources | yes | |
install_from | The resource where the install script will be run | no | |
ssh_port | The port to use for SSH | no | 22 |
admin_user | The admin user for all resources | yes | |
proximity_placement_group_name | The proximity group name to create | no | |
global_tags | Global tags to apply to all ARM resources | no |
The azhpc-build
command will generate an install script from the configuration file. This will be run from the install_from
VM. The install_from
VM must either have a public IP address or be accessible by hostname from where azhpc-build
is run (i.e. run azhpc-build
from a VM on the same vnet). The ssh_port
refers to an additional port number where the ssh daemon will listen on VMs with a public IP address. The NSG rules will only be applied to the ssh_port
number although port 22 will be accessible from within the vnet.
The config file will create or reuse vnet and subnets from the config file.

If a value is prefixed with variables.
then it will take the value from the proceeding JSON path under the variables section. For example:
{
"location": "variables.location",
"variables": {
"location": "westus2"
}
}
In the example above, the location will be taken from variables.location
.
The scripts allow secrets to be stored in keyvault. To read from keyvault use the following format: secret.<KEY-VAULT>.<KEY-NAME>
.
Note: this assumes the key vault is set up and the key is already stored there.
The config file can create a URL with a SAS key for a file in storage. This is the format: sasurl.<STORAGE-ACCOUNT>.<STORAGE-PATH>[,<PERMISSION>[,<DURATION>]]
. PERMISSIONS
are not required and is a list of letter for access permission : r
, w
, d
, l
. DURATION
is optional and is an integer value and a unit which can be either h
, d
, or y
(for hours, days, or years). The default for PERMISSIONS
is r
and the default for DURATION
is 2h
.
Note: the
<STORAGE-PATH>
should start at the container (and do not have a preceeding/
)
The scripts allow FQDN of resources to be retrieved. This is the format: fqdn.<RESOURCE-NAME>
.
Note: this assumes the resource name to be in the same resource group than the one defined in the configuration file.
The scripts allow PRIVATE IP of resources to be retrieved. This is the format: ip.<RESOURCE-NAME>
.
Note: this assumes the resource name to be in the same resource group than the one defined in the configuration file.
The scripts allow storage account key be retrieved. This is the format: sakey.<STORAGE-ACCOUNT>
.
Note: this assumes the storage account to be in the same resource group than the one defined in the configuration file.
The config file can create a SAS key for a file in storage. This is the format: saskey.<STORAGE-ACCOUNT>.<STORAGE-PATH>[,<PERMISSION>[,<DURATION>]]
. PERMISSIONS
are not required and is a list of letter for access permission : r
, w
, d
, l
. DURATION
is optional and is an integer value and a unit which can be either h
, d
, or y
(for hours, days, or years). The default for PERMISSIONS
is r
and the default for DURATION
is 2h
.
Note: the
<STORAGE-PATH>
should start at the container (and do not have a preceeding/
)
The config file allow to retrieve a Log Analytics workspace id. This is the format : laworkspace.<RESOURCE-GROUP>.<NAME>
.
Note : The Log Analytics Workspace
<NAME>
need to exists in the resource group<RESOURCE-GROUP>
The config file allow to retrieve a Log Analytics key. This is the format : lakey.<RESOURCE-GROUP>.<NAME>
.
Note : The Log Analytics Workspace
<NAME>
need to exists in the resource group<RESOURCE-GROUP>
The config file allow to retrieve an Azure Container Registry key. This is the format : acrkey.<ACR-REPONAME>
.
Note : The Azure Container Registry repositery
<ACR-REPONAME>
need to exists
The config file allow to retrieve a custom image id. This is the format : image.<RESOURCE-GROUP>.<NAME>
.
There are some situation where you want to use variable values inside other variables like a keyvault name or a storage account name. To do this just enclose it with double curly braces {{}}
like this :
"variables": {
"storage_account": "foo",
"storage_key": "sakey.{{variables.storage_account}}",
"la_resourcegroup": "myrg",
"la_name": "myla",
"log_analytics_workspace": "laworkspace.{{variables.la_resourcegroup}}.{{variables.la_name}}",
"log_analytics_key": "lakey.{{variables.la_resourcegroup}}.{{variables.la_name}}",
}
To set up the environment you first need to source $azhpc_dir/install.sh
. This is only required once and will create a bin
directory with all the commands aliases. It will also set the PATH
for the current session (and so there is no issue in running multiple times but you may prefer to just add the bin
directory to your bashrc).
The new version is now implemneted in Python and it will by default reuse the Python version provided as part of the Azure CLI.
Aliases have been created to allow an easier usage as well as a backward compatibility with the bash only version :

This is the command to create a Key Vault:
az keyvault create --name <keyvault-name> --resource-group <my-resource-group>
This is how you can add a secret:
az keyvault secret set --vault-name <keyvault-name> --name "<secret-name>" --value "<secret-vault>"
This can be accessed in the config file using the following value:
secret.<keyvault-name>.<secret-name>
The private key needs to have access rights of 0600; when using WSL on the NTFS drive (c: drive); that is by default not allowed. To get this working: add the metadata option to the mount:
sudo umount /mnt/c
sudo mount -t drvfs C: /mnt/c -o metadata
or better, have an wsl.conf which adds the metadata when starting:
[automount]
enabled=true
options=metadata,uid=1000,gid=1000,umask=022
