Azure Batch Samples

Here are a collection of samples to demonstrate the new features in this Batch preview CLI.

Hello World Samples

These samples use the new features in very simple ways to make it easier to see how these features might fit into your workflow.

Create pool and job

Create a pool and then run a job with a single task. Both the pool and the job are defined using templates with hard coded values.

Features used:

• Pool and job templates with parameterization
• Task collection task factory

Create pool and job with templates

Create a pool and then run a job with a single task. Both the pool and the job are defined using a parameterized templates. Parameter values used to fill out the templates are stored in separate files that are easy to modify as required.

Features used:

• Pool and job templates with parameterization
• Parametric sweep task factory
• Task per file task factory

Task per file

Run a specific piece of processing independently across a set of files that are uploaded into storage. The job is specified as a template accepting parameters.

Features used:

• Input data upload to Batch linked storage accounts
• Pool and job templates with parameterization
• Task per file task factory
• Automatic persistence of task output files to Azure Storage

Task per file with application template

Run a specific piece of processing independently across a set of files that are uploaded into storage. The actual processing involved is split out into a separate application template. The job itself references the template while specifying parameters, pool information and other management details. Application templates are intended to be flexible and reusable across a number of jobs.

Features used:

• Split job configuration and management with reusable application templates
• Task per file task factory
• Automatic persistence of task output files to Azure Storage

More Complex Samples

These samples show how to use the new features with real world applications.

FFmpeg

FFmpeg is an open-source command line tool for processing multimedia files. This is a sample demonstrating audio compression with Azure Batch on a large number of numerically-named files using a parametric sweep.

Features used:

• Job template with parameterization
• Automatic persistence of task output files to Azure Storage
• Easy software installation via package managers
• Parametric sweep task factory
• Task per file task factory

OCR

OCR (Optical Character Recognition) is the process of extracting text from PDF images. This sample demonstrates the batch processing of PDF files.

Features used:

• Pool and job templates with parameterization
• Parametric sweep task factory
• Automatic persistence of task output files to Azure Storage
• Easy software installation via package managers

MPI

This sample demonstrates the batch run a MPI task with MultiInstanceSettings feature.

Blender

Blender is an open-source 3D content creation suite. This sample demonstrates distributed rendering on Azure Batch.

Features used:

• Job template with parameterization
• Parametric sweep task factory
• Automatic persistence of task output files to Azure Storage
• Easy software installation via package managers

Blender (Application Template)

A variation of the Blender sample that uses an application template to separate job definiton and management.

Features used:

• Job template with parameterization
• Parametric sweep task factory
• Automatic persistence of task output files to Azure Storage
