The GNU Compilers are available as module and as part of the operating system. To see the other available versions of the GNU Compilers type
[abcd1234@hpcl001]$ module av GCC
which currently shows
---------------- /cm/local/modulefiles ---------------- gcc/6.1.0 ---------- /cm/shared/uniol/modules/compiler ---------- GCC/4.9.4-2.25 GCC/5.4.0-2.26 GCC/6.2.0-2.27 (D)
To load the module of your choice type e.g.
[abcd1234@hpcl001]$ module load GCC/4.9.4-2.25 [abcd1234@hpcl001]$ module list Currently loaded modules: ... GCC/4.9.4-2.25
The commands for the available languages are:
| Name | Description |
|---|---|
| gcc | C compiler |
| g++ | C++ compiler |
| gfortran | Fortran compiler |
Advantages
- high availability, open source (free)
- new standards implemented
- fast compilation
- performance of resulting C++ usually good
- most open source software tested with GNU
Disadvantages
- optimization of code is moderate: performance of C, Fortran code can be moderate
