parsl.providers.LocalProvider

class parsl.providers.LocalProvider(channel=LocalChannel( envs={}, script_dir=None, userhome='/home/docs/checkouts/readthedocs.org/user_builds/parsl/checkouts/0.9.0/docs' ), nodes_per_block=1, launcher=SingleNodeLauncher(), init_blocks=4, min_blocks=0, max_blocks=10, walltime='00:15:00', worker_init='', cmd_timeout=30, parallelism=1, move_files=None)

Local Execution Provider

This provider is used to provide execution resources from the localhost.

Parameters:

• 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.
• move_files (Optional[Bool]: should files be moved? by default, Parsl will try to figure) – this out itself (= None). If True, then will always move. If False, will never move.
• worker_init (str) – Command to be run before starting a worker, such as ‘module load Anaconda; source activate env’.

__init__(channel=LocalChannel( envs={}, script_dir=None, userhome='/home/docs/checkouts/readthedocs.org/user_builds/parsl/checkouts/0.9.0/docs' ), nodes_per_block=1, launcher=SingleNodeLauncher(), init_blocks=4, min_blocks=0, max_blocks=10, walltime='00:15:00', worker_init='', cmd_timeout=30, parallelism=1, move_files=None)

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