How can we measure the performance (run-time, memory usage etc) of our C++ code? And what does performance mean, anyway. These and other questions are the topic of this episode - with my guest Klaus Iglberger, C++ engineer, tutor and mentor.
Memory
- https://en.wikipedia.org/wiki/Non-uniform_memory_access something about memory access
- https://dl.acm.org/doi/10.1145/216585.216588 Ań article on 'Hitting the memory wall' how fast can memory access be?
- https://www.ibm.com/docs/en/xl-c-and-cpp-aix/13.1.3?topic=performance-managing-memory-efficiently-c-only what can we do to make memory usage more efficient
