IVF 10.0 Win/VS 2005 Profiling

How does one get a profile usage report by line or routine number for IVF
10.0, Win XP, VS-2005 ?

I can find all sorts of information on using Profile Guided Optimization
using /Qprof-gen and then /Qprof-use. But this is for optimizing during
compile. What I need is to see line times for an older version of a project
versus a newer version.

Intel's documentation does not seem to be very lucid on this.

Thanks.

Some progress: Need to use /Qprof-genx; compile with this flag; Run code;
Use profmerge.exe to turn *.dyn into *.dpi file; Use the codecov.exe to
create coverage information in html format.

But would like to get actual time spent by line or subroutine call. All I
can find in the codecov.exe options are a -counts option which report counts
by line. Need something like this, but with actual time.

Anyone know how?

Thanks.

The Intel Visual Fortran product does not include a profiler. There
is the Intel VTune Performance Analyzer, a separate product, for which
you can get a 30-day free trial. See
http://www.intel.com/cd/software/pr.../vpa/219898.htm
for more information.

As you've seen, the purpose of these profiling options is to get data on
relative frequency of branches etc. Running in an un-optimized mode, it
is not useful for actual timings.
As Steve already mentioned, Intel's primary offering for time and event
profiling is VTune; secondary offering is PTU (see
softwarecommunity.intel.com/forums). Other possibilities would be
oprofile based profilers, or a compiler which supports gprof (as Intel
linux compilers do),...

I would have mentioned PTU (http://whatif.intel.com/) but it requires
a VTune license (can be evaluation).
