By default, a Batch task is executed on a single compute node. By enabling multi-instance tasks, the task is executed on multiple compute nodes.
These multi-instance tasks are submitted to the Batch job and then distributed over the available nodes inside the Batch pool. Azure Batch automatically creates one primary task and several subtasks based on these multi-instance settings. The tasks that run in parallel use Azure Storage to save and retrieve the data that's used by the different tasks:
