Overview

Concrete tool for shutting down background disk I/O threads provided by the FlexLLMGen library.

Description

ExecutionEnv.close_copy_threads() delegates to self.disk.close_copy_threads() which terminates the background thread pool used for async tensor copies to/from NVMe disk.

Usage

Call as the final step in any FlexLLMGen workflow after generation is complete.
