parsl.providers.GoogleCloudProvider

class parsl.providers.GoogleCloudProvider(project_id, key_file, region, os_project, os_family, google_version='v1', instance_type='n1-standard-1', init_blocks=1, min_blocks=0, max_blocks=10, launcher=SingleNodeLauncher(debug=True, fail_on_any=False), parallelism=1)

A provider for using resources from the Google Compute Engine.

Parameters:

• project_id (str) – Project ID from Google compute engine.

• key_file (str) – Path to authorization private key json file. This is required for auth. A new one can be generated here: https://console.cloud.google.com/apis/credentials

• region (str) – Region in which to start instances

• os_project (str) – OS project code for Google compute engine.

• os_family (str) – OS family to request.

• google_version (str) – Google compute engine version to use. Possibilies include ‘v1’ (default) or ‘beta’.

• instance_type (str) – ‘n1-standard-1’,

• init_blocks (int) – Number of blocks to provision immediately. Default is 1.

• min_blocks (int) – Minimum number of blocks to maintain. Default is 0.

• max_blocks (int) – Maximum number of blocks to maintain. Default is 10.

• parallelism (float) – Ratio of provisioned task slots to active tasks. A parallelism value of 1 represents aggressive scaling where as many resources as possible are used; parallelism close to 0 represents the opposite situation in which as few resources as possible (i.e., min_blocks) are used.

__init__(project_id, key_file, region, os_project, os_family, google_version='v1', instance_type='n1-standard-1', init_blocks=1, min_blocks=0, max_blocks=10, launcher=SingleNodeLauncher(debug=True, fail_on_any=False), parallelism=1)

Methods

__init__(project_id, key_file, region, ...)
bye()
cancel(job_ids)	Cancels the resources identified by the job_ids provided by the user.
create_instance([command])
delete_instance(name)
get_zone(region)
status(job_ids)	Get the status of a list of jobs identified by the job identifiers returned from the submit request.
submit(command, tasks_per_node[, job_name])	The submit method takes the command string to be executed upon instantiation of a resource most often to start a pilot.

Attributes

status_polling_interval

bye()

cancel(job_ids)

Cancels the resources identified by the job_ids provided by the user.

Parameters:

job_ids (-) – A list of job identifiers

Returns:

• A list of status from cancelling the job which can be True, False

Raises:

- ExecutionProviderException or its subclasses –

create_instance(command='')

delete_instance(name)

get_zone(region)

status(job_ids)

Get the status of a list of jobs identified by the job identifiers returned from the submit request.

Parameters:

job_ids (-) – A list of job identifiers

Returns:

• A list of JobStatus objects corresponding to each job_id in the job_ids list.

Raises:

- ExecutionProviderException or its subclasses –

property status_polling_interval

submit(command, tasks_per_node, job_name='parsl.gcs')

The submit method takes the command string to be executed upon instantiation of a resource most often to start a pilot.

Args :

• command (str) : The bash command string to be executed.

• tasks_per_node (int) : command invocations to be launched per node

KWargs:

• job_name (str) : Human friendly name to be assigned to the job request

Returns:

• A job identifier, this could be an integer, string etc

Raises:

- ExecutionProviderException or its subclasses –
