Hello,

Are there any gfortran compile-time flags that could improve runtime timings upon the default '-O2 -ftree-vectorize -funroll-lopps', in a significant manner (i.e., more than say a few % improvement) ?

Thanks!
Richard H.
 
Hi Richard,
I'm not aware of anything that will make it run faster. Perhaps someone else in the community has some ideas.
