PerfUtils is a low-overhead library for doing performance analysis of highly-performant software systems running on x86_64.

1. Clone the repository.

    git clone https://github.com/PlatformLab/PerfUtils.git
   

2. Build the library.

    pushd PerfUtils
    make
    popd
   

3. Instrument your application, including the header files for the utilities you would like to use, with a PerfUtils prefix.

    #include "PerfUtils/TimeTrace.h"
   
    using PerfUtils::TimeTrace;
   
    int main(){
       TimeTrace::record("Start of execution");
       uint64_t sum = 0;
       for (int i = 0; i < (1 << 20); i++) {
           sum += i;
       }
       TimeTrace::record("End of a counting loop");
       TimeTrace::record("Hello world");
       TimeTrace::print();
    }
   

4. Build and link against PerfUtils.

    g++ -o Main -Ipath/to/PerfUtils/include -std=c++0x Main.cc  -Lpath/to/PerfUtils/lib -lPerfUtils
