Azure Batch libraries for python

Overview

Run large-scale parallel and high-performance computing applications efficiently in the cloud with Azure Batch.

To get started with Azure Batch, see Create a Batch account with the Azure portal.

Install the libraries

Client library

The Azure Batch client libraries let you configure compute nodes and pools, define tasks and configure them to run in jobs, and set up a job manager to control and monitor job execution. Learn more about using these objects to run large-scale parallel compute solutions.

pip install azure-batch

Example

Set up a pool of Linux compute nodes in a batch account:

# create the batch client for an account using its URI and keys
creds = batchauth.SharedKeyCredentials(account, key)
config = batch.BatchServiceClientConfiguration(creds, base_url = batch_url)
client = batch.BatchServiceClient(config)

# Create the VirtualMachineConfiguration, specifying
# the VM image reference and the Batch node agent to
# be installed on the node.
vmc = batchmodels.VirtualMachineConfiguration(
    image_reference = ir,
    node_agent_sku_id = "batch.node.ubuntu 14.04")

# Assign the virtual machine configuration to the pool
new_pool.virtual_machine_configuration = vmc

# Create pool in the Batch service
client.pool.add(new_pool)

Management API

Use the Azure Batch management libraries to create and delete batch accounts, read and regenerate batch account keys, and manage batch account storage.

pip install azure-mgmt-batch

Example

Create an Azure Batch account and configure a new application and Azure storage account for it.

from azure.mgmt.batch import BatchManagementClient
from azure.mgmt.resource import ResourceManagementClient
from azure.mgmt.storage import StorageManagementClient

LOCATION ='eastus'
GROUP_NAME ='batchresourcegroup'
STORAGE_ACCOUNT_NAME ='batchstorageaccount'

# Create Resource group
print('Create Resource Group')
resource_client.resource_groups.create_or_update(GROUP_NAME, {'location': LOCATION})

# Create a storage account
storage_async_operation = storage_client.storage_accounts.create(
    GROUP_NAME,
    STORAGE_ACCOUNT_NAME,
    StorageAccountCreateParameters(
        sku=Sku(SkuName.standard_ragrs),
        kind=Kind.storage,
        location=LOCATION
    )
)
storage_account = storage_async_operation.result()

# Create a Batch Account, specifying the storage account we want to link
storage_resource = storage_account.id
batch_account = azure.mgmt.batch.models.BatchAccountCreateParameters(
    location=LOCATION,
    auto_storage=azure.mgmt.batch.models.AutoStorageBaseProperties(storage_resource)
)
creating = batch_client.account.create('MyBatchAccount', LOCATION, batch_account)
creating.wait()
