Valgrind Study Notes (2)

Cachegrind: Cachegrind collects cpu statistics when the application is running by simulating the Level 1, 3 cache of the cpu, and prints detailed data and summary information.1. The following are some abbreviations of cpu statistics:I cache reads (Ir, which equals the number of instructions executed), I1 cache read misses (I1mr) and LL cache instruction read misses (ILmr ).D cache reads (Dr, which equals the number of memory reads), D1 cache read misses (D1mr), and LL cache data read misses (DLm
