Description

💡 What: Replaced list comprehensions [...] inside standard aggregate functions like sum(), any(), and all() with generator expressions (...) (or plain tuples for static items). Added comments explaining the changes.
🎯 Why: Python list comprehensions force the entire list to be allocated in memory before being passed to functions like sum(), any(), or all(). Generator expressions iterate lazily. For all() and any(), this also enables true short-circuit evaluation—stopping iteration immediately when False or True is hit respectively, saving CPU cycles and memory.
📊 Impact: Reduced memory overhead during the request scheduling/benchmarking/model execution phases. Faster failure conditions in metrics parsing.
🔬 Measurement: Verify that server latency doesn't spike during high waiting request lists (since resource_manager_v1.py iteration is more efficient), and overall node memory stays lower. Code passes pytest locally (if environment allows) and functions remain logically identical.
