Detailed Description

Use this tool to perf your thread in an easy way. Organized as Initialize and Get the perf results. The following is an example to use

ThreadPerf tp(-1, {PerfPair(COUNT_HW_CPU_CYCLES, "Cycles"), \
                   PerfPair(COUNT_HW_INSTRUCTIONS, "instructions")
               }
                   ); // creat a ThreadPerf with specific events
tp.start(); //start it
// run your program here
 tp.end();
 cout<<tp.headStringPrintf()<<endl;
 cout<<tp.resultStringPrintf()<<endl;
 //print the results
