Knew this one but still fumbled the prevention side a bit.
Start with a clear definition of a memory leak, then explain its impact in the context of performance-critical systems like NVIDIA's. Structure your answer by covering common causes, detection tools, and prevention strategies, emphasizing trade-offs and best practices.
Pro tip: Mention that prevention is more cost-effective than debugging, and highlight how NVIDIA's focus on performance makes memory management critical. Also, discuss the role of static analysis and code reviews in catching leaks early.
Explain that a memory leak occurs when allocated memory is not released, leading to increased memory usage and potential system degradation.
Describe common causes like forgotten free/delete, circular references, and unclosed resources. Emphasize the impact on performance, especially in long-running or resource-constrained systems.
Outline proactive measures such as using smart pointers (RAII), garbage collection, and proper resource management. Mention coding standards and peer reviews.
List tools like Valgrind, AddressSanitizer, and heap profilers. Explain how to integrate them into development and testing pipelines.
Discuss trade-offs between manual and automatic memory management, and the importance of balancing performance with safety. Highlight NVIDIA-specific considerations like GPU memory management.
