### What this PR does / why we need it? Fix Qwen3-30B-A3B dp parallel hung issue when running with the dp parallel example. For large-parameter models of Qwen3-30B and above, weight loading alone takes 4 to 5 minutes. Therefore, the 5-minute timeout in the current example code implementation is too short, causing some DP instances to be killed prematurely and eventually stuck in the DP synchronization all-reduce operation. ### Does this PR introduce _any_ user-facing change?
