Bug Gfortran compiler options.

I am a INTEL fortran user recently migrated to linux and installed gfortran on my system.

I run numerical models as part of my research.

my question is on optimization of the fortran code.

I used the - vectorize option to compile for reducing the run time considerably and was happy. But in gfortran i am not finding the same.

also how gfortran & f95 are different from each other? which one is better?!

help from anybody is welcome, love 2 hear any suggestion.

thanks in advance
