valgrind: Use the Cachegrind tool to profile and log CPU cache operations of `program`.

valgrind

$ valgrind --tool=cachegrind ${program}

try on your machine

The command "valgrind --tool=cachegrind ${program}" is used to run a program through the Valgrind tool with the Cachegrind tool enabled.

Valgrind is a programming tool used for debugging and profiling. It helps in detecting memory leaks, buffer overflows, and other memory-related errors in C, C++, and other languages.

Cachegrind, one of the tools bundled with Valgrind, is a cache and branch-prediction profiler. It simulates the behavior of the system's cache hierarchy to provide insights into cache performance and potential bottlenecks in a program.

By running a program with this command, Valgrind will analyze the program's memory usage and cache behavior, providing detailed information on cache misses, cache hits, and other cache-related performance metrics. This information helps in identifying inefficiencies in the program's memory usage and optimizing cache utilization for improved performance.
