parsl.providers.cluster_provider.ClusterProvider

class parsl.providers.cluster_provider.ClusterProvider(label, nodes_per_block, init_blocks, min_blocks, max_blocks, parallelism, walltime, launcher, cmd_timeout=10)

This class defines behavior common to all cluster/supercompute-style scheduler systems.

Parameters:

• label (str) – Label for this provider.

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

• launcher (Launcher) – Launcher for this provider.

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

__init__(label, nodes_per_block, init_blocks, min_blocks, max_blocks, parallelism, walltime, launcher, cmd_timeout=10)

Methods

__init__(label, nodes_per_block, ...[, ...])
cancel(job_ids)	Cancels the resources identified by the job_ids provided by the user.
execute_wait(cmd[, timeout])
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 (such as for HighThroughputExecutor or WorkQueueExecutor).

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.

execute_wait(cmd, timeout=None)

property label

Provides the label for this provider

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 –
