Google HPC-Toolkit

Description

HPC Toolkit is an open-source software offered by Google Cloud which makes it easy for customers to deploy HPC environments on Google Cloud.

HPC Toolkit allows customers to deploy turnkey HPC environments (compute, networking, storage, etc.) following Google Cloud best-practices, in a repeatable manner. The HPC Toolkit is designed to be highly customizable and extensible, and intends to address the HPC deployment needs of a broad range of customers.

Detailed documentation and examples

The Toolkit comes with a suite of tutorials, examples, and full documentation for a suite of modules that have been designed for HPC use cases. More information can be found on the Google Cloud Docs.

Quickstart

Running through the quickstart tutorial is the recommended path to get started with the HPC Toolkit.

If a self directed path is preferred, you can use the following commands to build the ghpc binary:

git clone https://github.com/GoogleCloudPlatform/hpc-toolkit
cd hpc-toolkit
make
./ghpc --version
./ghpc --help

NOTE: You may need to install dependencies first.

HPC Toolkit Components

Learn about the components that make up the HPC Toolkit and more on how it works on the Google Cloud Docs Product Overview.

GCP Credentials

Supplying cloud credentials to Terraform

Terraform can discover credentials for authenticating to Google Cloud Platform in several ways. We will summarize Terraform's documentation for using gcloud from your workstation and for automatically finding credentials in cloud environments. We do not recommend following Hashicorp's instructions for downloading service account keys.

Cloud credentials on your workstation

You can generate cloud credentials associated with your Google Cloud account using the following command:

gcloud auth application-default login

You will be prompted to open your web browser and authenticate to Google Cloud and make your account accessible from the command-line. Once this command completes, Terraform will automatically use your "Application Default Credentials."

If you receive failure messages containing "quota project" you should change the quota project associated with your Application Default Credentials with the following command and provide your current project ID as the argument:

gcloud auth application-default set-quota-project ${PROJECT-ID}

Cloud credentials in virtualized cloud environments

In virtualized settings, the cloud credentials of accounts can be attached directly to the execution environment. For example: a VM or a container can have service accounts attached to them. The Google Cloud Shell is an interactive command line environment which inherits the credentials of the user logged in to the Google Cloud Console.

Many of the above examples are easily executed within a Cloud Shell environment. Be aware that Cloud Shell has several limitations, in particular an inactivity timeout that will close running shells after 20 minutes. Please consider it only for blueprints that are quickly deployed.

VM Image Support

Standard Images

The HPC Toolkit officially supports the following VM images:

HPC CentOS 7
HPC Rocky Linux 8
Debian 11
Ubuntu 20.04 LTS

For more information on these and other images, see docs/vm-images.md.

Slurm Images

Warning: Slurm Terraform modules cannot be directly used on the standard OS images. They must be used in combination with images built for the versioned release of the Terraform module.

The HPC Toolkit provides modules and examples for implementing pre-built and custom Slurm VM images, see Slurm on GCP

Blueprint Validation

The Toolkit contains "validator" functions that perform basic tests of the blueprint to ensure that deployment variables are valid and that the HPC environment can be provisioned in your Google Cloud project. Further information can be found in dedicated documentation.

Enable GCP APIs

In a new GCP project there are several APIs that must be enabled to deploy your HPC cluster. These will be caught when you perform terraform apply but you can save time by enabling them upfront.

See Google Cloud Docs for instructions.

GCP Quotas

You may need to request additional quota to be able to deploy and use your HPC cluster.

See Google Cloud Docs for more information.

Billing Reports

You can view your billing reports for your HPC cluster on the Cloud Billing Reports page. To view the Cloud Billing reports for your Cloud Billing account, including viewing the cost information for all of the Cloud projects that are linked to the account, you need a role that includes the billing.accounts.getSpendingInformation permission on your Cloud Billing account.

To view the Cloud Billing reports for your Cloud Billing account:

In the Google Cloud Console, go to Navigation Menu > Billing.
At the prompt, choose the Cloud Billing account for which you'd like to view reports. The Billing Overview page opens for the selected billing account.
In the Billing navigation menu, select Reports.

In the right side, expand the Filters view and then filter by label, specifying the key ghpc_deployment (or ghpc_blueprint) and the desired value.

Troubleshooting

Authentication

Confirm that you have properly setup Google Cloud credentials

Slurm Clusters

Please see the dedicated troubleshooting guide for Slurm.

Terraform Deployment

When terraform apply fails, Terraform generally provides a useful error message. Here are some common reasons for the deployment to fail:

GCP Access: The credentials being used to call terraform apply do not have access to the GCP project. This can be fixed by granting access in IAM & Admin.
Disabled APIs: The GCP project must have the proper APIs enabled. See Enable GCP APIs.
Insufficient Quota: The GCP project does not have enough quota to provision the requested resources. See GCP Quotas.
Filestore resource limit: When regularly deploying Filestore instances with a new VPC you may see an error during deployment such as: System limit for internal resources has been reached. See this doc for the solution.
Required permission not found:
- Example: Required 'compute.projects.get' permission for 'projects/... forbidden
- Credentials may not be set, or are not set correctly. Please follow instructions at Cloud credentials on your workstation.
- Ensure proper permissions are set in the cloud console IAM section.

Failure to Destroy VPC Network

If terraform destroy fails with an error such as the following:

│ Error: Error when reading or editing Subnetwork: googleapi: Error 400: The subnetwork resource 'projects/<project_name>/regions/<region>/subnetworks/<subnetwork_name>' is already being used by 'projects/<project_name>/zones/<zone>/instances/<instance_name>', resourceInUseByAnotherResource

or

│ Error: Error waiting for Deleting Network: The network resource 'projects/<project_name>/global/networks/<vpc_network_name>' is already being used by 'projects/<project_name>/global/firewalls/<firewall_rule_name>'

These errors indicate that the VPC network cannot be destroyed because resources were added outside of Terraform and that those resources depend upon the network. These resources should be deleted manually. The first message indicates that a new VM has been added to a subnetwork within the VPC network. The second message indicates that a new firewall rule has been added to the VPC network. If your error message does not look like these, examine it carefully to identify the type of resource to delete and its unique name. In the two messages above, the resource names appear toward the end of the error message. The following links will take you directly to the areas within the Cloud Console for managing VMs and Firewall rules. Make certain that your project ID is selected in the drop-down menu at the top-left.

Inspecting the Deployment

The deployment will be created with the following directory structure:

<<OUTPUT_PATH>>/<<DEPLOYMENT_NAME>>/{<<DEPLOYMENT_GROUPS>>}/

If an output directory is provided with the --output/-o flag, the deployment directory will be created in the output directory, represented as <<OUTPUT_PATH>> here. If not provided, <<OUTPUT_PATH>> will default to the current working directory.

The deployment directory is created in <<OUTPUT_PATH>> as a directory matching the provided deployment_name deployment variable (vars) in the blueprint.

Within the deployment directory are directories representing each deployment group in the blueprint named the same as the group field for each element in deployment_groups.

In each deployment group directory, are all of the configuration scripts and modules needed to deploy. The modules are in a directory named modules named the same as the source module, for example the vpc module is in a directory named vpc.

A hidden directory containing meta information and backups is also created and named .ghpc.

From the hpc-slurm.yaml example, we get the following deployment directory:

hpc-slurm/
  primary/
    main.tf
    modules/
    providers.tf
    terraform.tfvars
    variables.tf
    versions.tf
  .ghpc/

Dependencies

See Cloud Docs on Installing Dependencies.

Notes on Packer

The Toolkit supports Packer templates in the contemporary HCL2 file format and not in the legacy JSON file format. We require the use of Packer 1.7.9 or above, and recommend using the latest release.

The Toolkit's Packer template module documentation describes input variables and their behavior. An image-building example and usage instructions are provided. The example integrates Packer, Terraform and startup-script runners to demonstrate the power of customizing images using the same scripts that can be applied at boot-time.

Development

The following setup is in addition to the dependencies needed to build and run HPC-Toolkit.

Please use the pre-commit hooks configured in this repository to ensure that all changes are validated, tested and properly documented before pushing code changes. The pre-commits configured in the HPC Toolkit have a set of dependencies that need to be installed before successfully passing.

Follow these steps to install and setup pre-commit in your cloned repository:

Install pre-commit using the instructions from the pre-commit website.
Install TFLint using the instructions from the TFLint documentation.

NOTE: The version of TFLint must be compatible with the Google plugin version identified in tflint.hcl. Versions of the plugin >=0.20.0 should use tflint>=0.40.0. These versions are readily available via GitHub or package managers. Please review the TFLint Ruleset for Google Release Notes for up-to-date requirements.

Install ShellCheck using the instructions from the ShellCheck documentation
The other dev dependencies can be installed by running the following command in the project root directory:
```
make install-dev-deps
```
Pre-commit is enabled on a repo-by-repo basis by running the following command in the project root directory:
```
pre-commit install
```

Now pre-commit is configured to automatically run before you commit.

Development on macOS

While macOS is a supported environment for building and executing the Toolkit, it is not supported for Toolkit development due to GNU specific shell scripts.

If developing on a mac, a workaround is to install GNU tooling by installing coreutils and findutils from a package manager such as homebrew or conda.
