PerfScope

Harness the power of performance counters, akin to tools like perf, but scoped within your C++ applications. This project provides a seamless way to measure and analyze performance metrics within defined scopes.

• Only limited to the perf_hw_id Generalized performance event (More coming soon).

Example

#include "PerfScope.h"

int main() {
  volatile uint64_t x = 0;
  {
    auto tmp = PerfScope<
      PERF_COUNT_HW_CACHE_REFERENCES,
      PERF_COUNT_HW_CACHE_MISSES,
      PERF_COUNT_HW_BRANCH_INSTRUCTIONS,
      PERF_COUNT_HW_BRANCH_MISSES>();

    for(int i = 0; i < 100000; i++){
      x+=i;
    }
  }
  
  return 0;
}
