https://community.hpe.com/t5/operating-system-hp-ux/gprof/m-p/2789229#M720456 Hello,<BR />I'm using an f77 compiler. Is using gprof as easy as:<BR />f77 -G file.f<BR />gprof a.out<BR /><BR />Because that is what I understand from the manual. Yes, I did set GPROFDIR to my cwd.<BR />Thanks,<BR />Cody Mon, 19 Aug 2002 21:34:41 GMT Cody Godines_1 2002-08-19T21:34:41Z https://community.hpe.com/t5/operating-system-hp-ux/gprof/m-p/2789229#M720456 Hello,<BR />I'm using an f77 compiler.

The gprof command will read that gmon.out and format it using the symbol information from a.out.<BR />Depending on the HP-UX release that you are using, you may also want to try some of the other profiling tools like puma, cxperf, caliper, or prospect. Different tools work on different releases. They each have their own strengths and weaknesses. (The most troubling weakness of gprof is that it is usually blind to time spent in shared libraries.)
