Gfortran -- compiler optimization
In all our examples we use the compiler option -O2. A few simple tests have shown that the option -O3 is significantly better in some cases. I have not tested this extensively, but maybe someone could confirm this.
Great, thanks Charlotte! I'm not currently doing much large-scale calculations with GRASP so someone with a more up to date runtime experience should give their opinion on this! I guess you're referring to gfortran-9 or 10, or what compiler do you use?
I may have been using version 6. I now have 7.5 .

Just one related factoid: I believe the CMake build defaults to -O3 anyway.
