AdHocProvider
(channels=[], worker_init='', cmd_timeout=30, parallelism=1, move_files=None)[source]¶ Ad-hoc execution provider
This provider is used to provision execution resources over one or more ad hoc nodes that are each accessible over a Channel (say, ssh) but otherwise lack a cluster scheduler.
Parameters: - channels (list of Channel ojects) – Each channel represents a connection to a remote node
- worker_init (str) – Command to be run before starting a worker, such as ‘module load Anaconda; source activate env’. Since this provider calls the same worker_init across all nodes in the ad-hoc cluster, it is recommended that a single script is made available across nodes such as ~/setup.sh that can be invoked.
- cmd_timeout (int) – Duration for which the provider will wait for a command to be invoked on a remote system. Defaults to 30s
- parallelism (float) – Determines the ratio of workers to tasks as managed by the strategy component
