parsl.providers.LSFProvider

class parsl.providers.LSFProvider(channel=LocalChannel( envs={}, script_dir=None, userhome='/home/docs/checkouts/readthedocs.org/user_builds/parsl/checkouts/0.9.0/docs' ), nodes_per_block=1, init_blocks=1, min_blocks=0, max_blocks=10, parallelism=1, walltime='00:10:00', scheduler_options='', worker_init='', project=None, cmd_timeout=120, move_files=True, launcher=SingleNodeLauncher())[source]

LSF Execution Provider

This provider uses sbatch to submit, squeue for status and scancel to cancel jobs. The sbatch script to be used is created from a template file in this same module.

Parameters:
  • channel (Channel) – Channel for accessing this provider. Possible channels include LocalChannel (the default), SSHChannel, or SSHInteractiveLoginChannel.
  • nodes_per_block (int) – Nodes to provision per block.
  • init_blocks (int) – Number of blocks to request at the start of the run.
  • 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.
  • project (str) – Project to which the resources must be charged
  • scheduler_options (str) – String to prepend to the #SBATCH 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’.
  • cmd_timeout (int) – Seconds after which requests to the scheduler will timeout. Default: 120s
  • launcher (Launcher) –
    Launcher for this provider. Possible launchers include
    SingleNodeLauncher (the default), SrunLauncher, or AprunLauncher

    move_files : Optional[Bool]: should files be moved? by default, Parsl will try to move files.
__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, init_blocks=1, min_blocks=0, max_blocks=10, parallelism=1, walltime='00:10:00', scheduler_options='', worker_init='', project=None, cmd_timeout=120, move_files=True, launcher=SingleNodeLauncher())[source]
