Human: This doesn’t actually guarantee that the tasks are assigned to different processes. Do you see why?
Claude: You're right, this code doesn't actually guarantee that the tasks are assigned to different processes. Here's why:
- The
ProcessPoolExecutor
creates a pool of worker processes, but it doesn't guarantee that each task will run in a separate process. It may reuse processes for multiple tasks. - The
executor.map()
function distributes tasks to the available worker processes, but it doesn't ensure a one-to-one mapping between tasks and processes. - Setting the
CUDA_VISIBLE_DEVICES
environment variable within theprocess_task
function doesn't affect the process allocation. It only limits which GPUs are visible to the current process after it has already been created.
