Yes. I use:

# Compile once with -fprofile-generate
for I in `head -n 1 quick.par`; do
  echo "Compiling (-fprofile-generate): $I"
  time gfortran -fprofile-generate -march=opteron -ffast-math
-funroll-loops -ftree-vectorize -msse3 -O3 -o $I $I.f90
  echo "Running once (-fprofile-generate): $I"
  time ./$I
done

# Run with profile-based optimization
../pbharness gfortranProf.par  quick.par

with gfortranProf.par:
gfortran -fprofile-use -march=opteron -ffast-math -funroll-loops
-ftree-vectorize -msse3 -O3 %n.f90 -o %n
