Reference documentation and code samples for the Google Cloud Batch V1 Client class TaskGroup.
A TaskGroup contains one or multiple Tasks that share the same Runnable but with different runtime parameters.

__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ name
string
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".
↳ task_spec
↳ task_count
int|string
Number of Tasks in the TaskGroup. Default is 1.
↳ parallelism
int|string
Max number of tasks that can run in parallel. Default to min(task_count, 1000). Field parallelism must be 1 if the scheduling_policy is IN_ORDER.
↳ task_environments
array< Google\Cloud\Batch\V1\Environment
>
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_count_per_node
int|string
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.
↳ require_hosts_file
bool
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. Defaults to false.
↳ permissive_ssh
bool
When true, Batch will configure SSH to allow passwordless login between VMs running the Batch tasks in the same TaskGroup.
