whick is the best fortran95 compiler in linux, i want a x window version. not a command line version. thank you very much

April 13, 2005, 10:12

intel ifc, but if there's a x window version, it's paid.

i really appreciate your answer,but where can i downlaod the intel ifc. thank you again.

at http://www.intel.com/software/products/noncom/ you will find the fortran and C++ compilers, and also other free softwares for noncomercial purposes. But as far as I know, there's no graphic interface for the free versions.

Tell me more. What is it that makes Intel's compiler better than the Absoft or Portland Group (or other) compilers, besides offering a free academic version?

April 13, 2005, 14:48

I don't know, and I didn't mean to do any advertising. I just mentioned ifc because, since it's free, you may try it before deciding if you're gonna buy it or not.

Intel's fortran compiler produces really fast code. We have been using Absoft for a long time but are considering switching to Intel now.

April 13, 2005, 20:20

You mean fast compilation or generation of fast executables?

April 13, 2005, 20:27

Nevermind the previous post, I got it. Just tell me which versions (absoft,intel) you mean. I am using absoft v8.0 and am quite satisfied with it. Also tried the ifc at one point, but was completely turned off by the long compilation times, without seeing much faster executables. Maybe the newer version is better.

<www.g95.org> Works well for me...

Surely compilation times for CFD are irrelevant if you are doing anything other than 1D test cases?

April 15, 2005, 03:35

Hi,

pathscale fortran looks pretty fast.

It depends. If you are mostly working on CFD applications compilation time is irrelevant. If you are developing the code it's a different story.

April 18, 2005, 04:37

In that case, develop your code using no optimisation. All compilers are quick if you give them an easier problem to solve. Then when you want to solve something real, recompile optimised.

Alternatively, develop using a toy compiler and then use an industrial strength one for release versions.
