Uri,
I'm not sure what operating system you are using but under Linux (with gnu
make) I use the following command line switches to generate first the
profile enabled version and then the final version.
It's a three step process:
1) Create the profiled-enabled version using the command "make intel_prof".
2) Run the new version against other programs, test suites or on ICC.
The idea is to run it as it would typically be used, so that the
optimization
data is gathered for the right parts of your program.
3) Remove all the object files (*.o files under Linux) in your build directory.
Remake the program using the "make intel_use" command.
There are tons of other optimization switches that you can experiment with,
the Intel manual has an informative section worth looking over. The main
idea is that you should (mostly) keep the switches the same between the
first version and the second version. When that isn't true the compiler will
usually complain.
One quick note, you will need to create the profile directory "profile" if you
use these flags as presented.
good luck,
