parsl.providers.GridEngineProvider

class parsl.providers.GridEngineProvider(nodes_per_block=1, init_blocks=1, min_blocks=0, max_blocks=1, parallelism=1, walltime='00:10:00', scheduler_options='', worker_init='', launcher=SingleNodeLauncher(debug=True, fail_on_any=False), cmd_timeout: int = 60, queue=None)

A provider for the Grid Engine scheduler.

Parameters:

• nodes_per_block (int) – Nodes to provision per block.

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

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

• 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.

• walltime (str) – Walltime requested per block in HH:MM:SS.

• scheduler_options (str) – String to prepend to the #$$ blocks in the submit script to the scheduler.

• worker_init (str) – Command to be run before starting a worker, such as ‘module load Anaconda; source activate env’.

• launcher (Launcher) – Launcher for this provider. Possible launchers include SingleNodeLauncher (the default),

• cmd_timeout (int) – Timeout for commands made to the scheduler in seconds

__init__(nodes_per_block=1, init_blocks=1, min_blocks=0, max_blocks=1, parallelism=1, walltime='00:10:00', scheduler_options='', worker_init='', launcher=SingleNodeLauncher(debug=True, fail_on_any=False), cmd_timeout: int = 60, queue=None)

Methods

__init__([nodes_per_block, init_blocks, ...])
cancel(job_ids)	Cancels the resources identified by the job_ids provided by the user.
execute_wait(cmd[, timeout])
get_configs(command, tasks_per_node)	Compose a dictionary with information for writing the submit script.
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

cores_per_node	Number of cores to provision per node.
label	Provides the label for this provider
mem_per_node	Real memory to provision per node in GB.
status_polling_interval	Returns the interval, in seconds, at which the status method should be called.

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 –

get_configs(command, tasks_per_node)

Compose a dictionary with information for writing the submit script.

property status_polling_interval

Returns the interval, in seconds, at which the status method should be called.

Returns:

the number of seconds to wait between calls to status()

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

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 –
