Question:
What is a good Fortran compiler/implementation these days?
I know they have Intel and IBM and SimplyFortran as commercial software. GFortran works via GCC. Is it as good? Has anyone on here used this LFortran.
- atemerev 7y agoEverybody I know in public science (physics) uses gfortran, works just fine.
- new4thaccount 7y agoGood to know, thanks! I've used software compiled with the Intel compiler, but have only written some toy programs in GFortran and it seems fast enough. I like the revival idea behind LFortran though. Reading scientific C++ is much more difficult than Fortran.
- septc 7y agoGfortran is very nice, but I recommend a recent version (at least ver >= 7) rather than old versions (e.g. ver 4.4, which may still be the default on CentOS 6 etc). For performance, I guess Intel fortran is probably better (but also depends on calculations).
- new4thaccount 7y agoThanks!
- certik 7y agoThe best open source implementation is GFortran. Just make sure you use a recent version, as others mentioned. Regarding commercial implementations, I only have experience with Intel and NAG, both of which are very good.
