Multithreaded application instrumentation example

Edit online

When placing instrumentation inside of parallel regions, you should use a different ID for each thread.

The following is an example multithreaded application instrumentation:
!$OMP PARALLEL
!$OMP&PRIVATE (instID)
     instID = 30+omp_get_thread_num()
     call f_hpmtstart( instID, "computing meaning of life" )
!$OMP DO
      do ...
       do_work()
      end do
      call f_hpmtstop( instID )
!$OMP END PARALLEL
The library accepts the use of the same instID for different threads, but the counters are accumulated for all instances with the same instID.
