prebuilt binaries with intel fortran compiler #27

Closed zimmermm closed 5 years ago

d-vanzo commented 5 years ago

why would you need this? (i.e. why the gfortran version is not enough?)

zimmermm commented 5 years ago

because the code runs significantly faster when compiled with the intel compiler

d-vanzo commented 5 years ago

Yeah, in general Intel one produces slightly/moderately faster exec, I agree. But if the difference is considerable maybe it is because of the optimization flag (in the fobos file Gnu is set to -O2, while Intel to -O3)... Have you tested gnu compiler with -O3 (or -Ofast even)?

zimmermm commented 5 years ago

yeah, intel is still faster

zimmermm commented 5 years ago

hmm.. but maybe this will be a licence issue then?

Good point. I guess yes, it might be not legal to do it.
