The GNU Compilers are available as module and as part of the operating system. The compiler of the operating system is GNU 4.8.5. 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
