Re: profile g95

I use mingw g95 on Windows XP. Is there a profiling tool to measure how
CPU time is consumed, or should I just sprinkle calls to the CPU_TIME
intrinsic in the code? If there is a tool that works only on Linux, I
could profile the code there -- I'd guess that the timings should be
similar.

There has been a rather detailed mail in the gg95 google group :
HOWTO: execution time profiling with
g95/valgrind/callgrind/kcacheg­rind

http://groups.google.com/group/gg95/browse_frm/thread/dab64d1ce9b8d80e/#

which describes a linux-only tool, which is, however very instructive
and very detailed (i.e. line by line timings). The standard tool, which
should also be available for mingw (but I can't test), is gprof. It
requires that the code is recompiled/linked with -pg. The executable
will generate a timing report (gmon.out) which can be transformed in
something more or less readable with gprof.
