Using compilers on compute nodes

Because the operating system on the compute nodes is "diskless", the programming environment is not complete there. Typically you have to compile and link on the login nodes. Also you have to load the following module , if you want to use limited functions of the compilers on the compute nodes

module load slurm_setup


Programming Languages
LanguageShort description
C, C++

C is a versatile language targetted at systems programming, but also used for scientific data processing. C++ defines an extension of C that is more application-centric due to availability of powerful object-oriented, generic and other programming paradigms.

Intel Compiler, GNU GCC, Portland Group Compilers
Fortran Programming language targeted at massive data processing and number crunching in the area of scientific computing. See the linked article for compiler support. All compiler suites mentioned for C/C++ also contain a Fortran compiler.
Intel Compiler, GNU GCC, Portland Group Compilers
JavaObject oriented, portable and powerful programming language for business applications, but also increasingly used in other areas.
PythonInterpreted, high-level, general-purpose programming language.
