General RTENOTITLE Tips

GNU and intel compilers are both available on our servers. We have a very limited number of licenses for intel compilers so we suggest you to use GNU compilers for all your development.

There is a default GNU compiler but it may be a quite old version. If you wish to use a newer version:

module avail gcc

it returns the list of available versions.

module load gcc/4.9.0

It loads GNU compilers 4.9.0 (both Fortran, C and C++ compilers).

Intel compilers are available by default on our UIO servers but on abel, you would need to load it:

module load intel

• Gunnar Wollan has compiled a set of documents at http://folk.uio.no/gunnarw/GEO4060/ and you can also find some of his documents at http://www.uio.no/studier/emner/matnat/geofag/GEF4510/h12/index.html

• An interesting free tutorial at http://www.fortrantutorial.com/ You can skip the installation of silverfrost compilers if you already have a Fortran compiler installed on your machine or if you are using sverdrup.uio.no

• The National Computational Infrastructure in Australia has class notes online for a Basic Fortran course (http://nf.nci.org.au/training/FortranBasic/) and an Advanced Fortran course (http://nf.nci.org.au/training/FortranAdvanced/).
