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.f90then I run the program
and then compile it again:
ifort -prof-use hello.f90but 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.
