Overview
A TaskGroup contains one or multiple Tasks that share the same Runnable but with different runtime parameters.
Instance Attribute Summary collapse
-
#name ⇒ ::String
readonly
Output only.
-
#parallelism ⇒ ::Integer
Max number of tasks that can run in parallel.
-
#permissive_ssh ⇒ ::Boolean
When true, Batch will configure SSH to allow passwordless login between VMs running the Batch tasks in the same TaskGroup.
-
#require_hosts_file ⇒ ::Boolean
When true, Batch will populate a file with a list of all VMs assigned to the TaskGroup and set the BATCH_HOSTS_FILE environment variable to the path of that file.
-
#task_count ⇒ ::Integer
Number of Tasks in the TaskGroup.
-
#task_count_per_node ⇒ ::Integer
Max number of tasks that can be run on a VM at the same time.
-
#task_environments ⇒ ::Array<::Google::Cloud::Batch::V1::Environment>
An array of environment variable mappings, which are passed to Tasks with matching indices.
-
#task_spec ⇒ ::Google::Cloud::Batch::V1::TaskSpec
Required.
Instance Attribute Details
#name ⇒ ::String (readonly)
Returns Output only. TaskGroup name. The system generates this field based on parent Job name. For example: "projects/123456/locations/us-west1/jobs/job01/taskGroups/group01".

#parallelism ⇒ ::Integer
Returns Max number of tasks that can run in parallel. Default to min(task_count, 1000).

#task_count ⇒ ::Integer
Returns Number of Tasks in the TaskGroup. default is 1.

#task_count_per_node ⇒ ::Integer
Returns Max number of tasks that can be run on a VM at the same time. If not specified, the system will decide a value based on available compute resources on a VM and task requirements.

#task_environments ⇒ ::Array<::Google::Cloud::Batch::V1::Environment>
Returns An array of environment variable mappings, which are passed to Tasks with matching indices. If task_environments is used then task_count should not be specified in the request (and will be ignored). Task count will be the length of task_environments.
Tasks get a BATCH_TASK_INDEX and BATCH_TASK_COUNT environment variable, in addition to any environment variables set in task_environments, specifying the number of Tasks in the Task's parent TaskGroup, and the specific Task's index in the TaskGroup (0 through BATCH_TASK_COUNT - 1).
task_environments supports up to 200 entries.

#task_spec ⇒ ::Google::Cloud::Batch::V1::TaskSpec
