endif identified for 100% of cpu time

pgprof identifies endif statements as taking all the time in my program, which runs for two minutes. I had hoped for detailed information. The following flags specify single threading, no optimization, no GPU? I’m not yet all that familiar with pgfortran flags and it’s possible that one of the later options increases the optimization level. I saw no message indicating this.

Please advise. I’d like to see detailed profiling information. Optimization is the only reason I can think of to cause the result, that’s why I mention it. Maybe there are other flags to enhance the profiled code? pgcollect didn’t work with this program, probably because the source is not contained in a single directory. Thank you, Dave.

Hi David,

I sent this to our Tools group but unfortunately, they aren’t sure. Is it possible to send us a reproducing example?

They would also be interested in investigating why pgcollect didn’t work with it.

Thanks,
Mat

Please don’t hold your breath awaiting a response. Could take a month. I’ll try to provide a minimal (smaller, anyway) source that reproduces the issue. I add that when I profiled only two of the source files by line,
-Mprof=lines
that of the main program and that containing the next-level interesting subroutine pgprof worked as expected.
