Hi everyone, I'm using the lastest ifort 12.1.5 and I'm tesing the pgo (profile-guided optimization) feature, but encoutered problems.
Here's my program, a quite simple hello world:
program main
print *, "hello"
end program main
then i compile it like this:
ifort -prof-gen hello.f90
then I run the program
./a.out
and then compile it again:
ifort -prof-use hello.f90
but I got the following error message:
/tmp/hello.f90(1): warning #11507: Value profiling mismatch for 'MAIN__'.
Does anyone know why? did I miss something?
Thanks.
