Parallelism
public long Parallelism { get; set; }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.

RequireHostsFile
public bool RequireHostsFile { get; set; }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.

long | |
TaskCountPerNode
public long TaskCountPerNode { get; set; }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.
| Property Value | |

TaskEnvironments
public RepeatedField<Environment> TaskEnvironments { get; }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.
