Azure HPC Cloud Deployment and Management

Azure HPC Cloud Deployment and Management is a game-changer for businesses and organizations that need to process large amounts of data.

With Azure HPC, you can deploy and manage high-performance computing (HPC) clusters in the cloud, which can significantly reduce costs and increase scalability.

Azure HPC provides a range of tools and services to manage your HPC workloads, including Azure Batch, Azure Databricks, and Azure Machine Learning.

These tools enable you to automate and orchestrate your HPC workloads, making it easier to manage complex computing tasks and improve productivity.

To set up an Azure HPC cluster, you'll need to configure several key settings. The azhpc-build command requires specific information, which can be found in the setup information table.

Here are the required settings:

You can also configure additional settings, such as the SSH port and proximity placement group name, but they are not required.

To set up your environment, you'll need to specify some key information. The location of the resources is a required field, so make sure you have that ready.

The resource group to put the resources is also a required field, so don't forget to include that. You can leave the install_from field blank if you don't need it.

The admin_user is a required field, and you'll need to specify the admin user for all resources. The ssh_port is optional, but if you want to use a different port for SSH, you can specify it.

Here's a table summarizing the required fields:

The install array process is a crucial step in setting up your system. It's where you create an install script from a list of steps that will be run on the install_from VM.

Each step in the install array is a dictionary containing several key pieces of information. The script to run is required and should be the name of the script to execute, with the path relative to either $azhpc_dir/scripts or a local scripts directory for the project.

The tag is also required and is used to select which resources will run this step. This is a critical piece of information, as it determines which resources will be affected by the install array.

The sudo flag is optional and defaults to False. This means that the script will not be run with superuser privileges by default. However, if you need to run the script with sudo, you can set this flag to True.

The deps, args, and copy keys are optional and allow you to specify dependent files, arguments for the script, and files to copy to each resource, respectively. These can be useful for more complex installations, but are not required for a basic install array.

Here is a summary of the required keys for each step in the install array:

Init is a crucial step in setting up a project, and azhpc-init is the utility that makes it happen. It initialises a new project and can set variables in the config file.

You can use azhpc-init to copy contents from a directory to the new project directory, and it will replace variables in JSON files. This is a great way to get started with a new project.

The -s option is also available, which can be used to search for variables that are not set in a config file. The output will include all the variables to set, which can be helpful in getting your project up and running.

Cloud Deployment is a critical aspect of Azure HPC. Azure offers several tools to help you manage and deploy your HPC workloads, including Microsoft HPC Pack, Azure CycleCloud, and Azure Batch.

Azure HPC Pack is a set of utilities that enables you to configure and manage VM clusters, monitor operations, and schedule workloads. It's a powerful tool for managing your HPC deployments.

To distribute large deployments across cloud services, you can split your deployment into smaller segments. This helps avoid limitations created by overloading or relying on a single service. By splitting your deployment, you can stop idle instances after job completion without interrupting other processes.

You can split deployments across up to 32 services, with a maximum of 500 VMs or 1000 cores per service. This approach also enables you to flexibly start and stop node clusters, making it easier to find available nodes in your clusters.

Proxy nodes are essential for communication between head nodes and Azure worker nodes. Increasing proxy node instances can help match deployment size, especially for large jobs that meet or exceed the resources provided by the proxy nodes.

Here are some key considerations for cloud deployment:

Azure HPC Solution Components are designed to support a variety of high-performance computing (HPC) scenarios, including 3D video rendering, computer-aided engineering, and digital image-based modeling on Azure.

Azure HPC Compute components include High Performance VMs, GPU Accelerated VMs, and Memory Optimized VMs, which provide the necessary processing power and memory for demanding HPC workloads.

Azure HPC Storage components include Azure NetApp Files and Azure Blob Storage, which provide scalable and high-performance storage solutions for HPC clusters.

HPC applications can scale to thousands of compute cores, extend on-premises clusters, or run as a 100% cloud-native solution. There are many different ways to design and implement your HPC architecture on Azure.

A software-as-a-service (SaaS) platform for computer-aided engineering (CAE) on Azure is a common architecture scenario. This allows users to access CAE tools and applications from anywhere, on any device, and on any platform.

To create a pure cloud HPC deployment or a hybrid deployment supplemented by cloud resources, you can use Azure resources. This results in shorter processing times and an ability to perform significantly more complex operations with compute-optimized virtual machines (VMs) or GPU-enabled instances.

Here are some common HPC architecture scenarios:

These scenarios can be used as a starting point for designing and implementing your own HPC architecture on Azure. By choosing the right architecture, you can ensure that your HPC cluster is optimized for performance, scalability, and cost-effectiveness.

Containers are a great way to manage some HPC workloads, and Azure makes it easy to get started.

Azure Kubernetes Service (AKS) is a managed service that lets you deploy a Kubernetes cluster in Azure with just a few clicks. This means you can focus on your application code without worrying about the underlying infrastructure.

AKS integrates well with other Azure services, making it a great choice for HPC workloads.

Azure Container Registry is another important tool for managing containers in Azure. It allows you to store and manage your container images in a central location.

Here are some of the key services you'll need to manage containers in Azure:

Managing deployments in Azure HPC involves using native services to configure and manage VM clusters, monitor operations, and schedule workloads. You can use Microsoft HPC Pack to do this.

Azure provides a few native services to help you manage your HPC deployments, including Azure CycleCloud, Azure Batch, and Microsoft HPC Pack. These tools provide flexibility for management and can help you schedule workloads in Azure as well as in hybrid resources.
