Chunel focused on improving the stability and reliability of the core execution engine in the nndeploy/nndeploy repository, addressing a concurrency issue in the thread pool’s task stealing mechanism. By implementing a safety check to ensure the target pool exists and is non-empty before stealing tasks, Chunel eliminated the risk of null pointer dereferences and improved task distribution under concurrent load. The solution, developed in C++ with an emphasis on multithreading and bug fixing, was validated through targeted tests and code safeguards. This work enhanced runtime throughput consistency and reduced scheduling risk, contributing to more predictable deployment pipelines for users and teams.
