PBSProProvider
(channel=LocalChannel( envs={}, script_dir=None, userhome='/home/docs/checkouts/readthedocs.org/user_builds/parsl/checkouts/0.9.0/docs' ), account=None, queue=None, scheduler_options='', worker_init='', nodes_per_block=1, cpus_per_node=1, init_blocks=1, min_blocks=0, max_blocks=100, parallelism=1, launcher=SingleNodeLauncher(), walltime='00:20:00', cmd_timeout=120)[source]¶ PBS Pro 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
, orSSHInteractiveLoginChannel
. - account (str) – Account the job will be charged against.
- queue (str) – Queue to request blocks from.
- nodes_per_block (int) – Nodes to provision per block.
- cpus_per_node (int) – CPUs to provision per node.
- init_blocks (int) – Number of blocks to provision at the start of the run. Default is 1.
- min_blocks (int) – Minimum number of blocks to maintain. Default is 0.
- 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 #PBS 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. The default is
SingleNodeLauncher
.
