To get useful information from Pgprof, you first need to compile your code with one of the PGI compilers (<code>pgcc</code> for C, <code>pgc++</code> for C++ , <code>pgfortran</code> for Fortran). A source in Fortran may need to be compiled with the <code>-g</code> flag. | To get useful information from Pgprof, you first need to compile your code with one of the PGI compilers (<code>pgcc</code> for C, <code>pgc++</code> for C++ , <code>pgfortran</code> for Fortran).
