parsl.providers.cluster_provider.ClusterProvider

class parsl.providers.cluster_provider.ClusterProvider(label, channel, 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.

• channel (Channel) – Channel for accessing this provider. Possible channels include LocalChannel (the default), SSHChannel, or SSHInteractiveLoginChannel.

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

• launcher (str) – FIXME

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

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

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(label, channel, nodes_per_block, …)	Initialize self.
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 IPP engine or even Swift-T engines).

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.
