GNU Compiler Collection (gcc)
The GNU Compiler Collection (gcc) is a widely used, free collection of compilers for C (gcc), C++ (g++) and Fortran (gfortran).
It is possible to switch versions of the gcc compiler suite using modules. After connecting to Bessemer, start an interactive sessson:
srun --pty bash -i
then choose the version of the compiler you wish to use by running one of the following lines:
module load GCC/8.3.0 # part of the foss-2019b toolchain
module load GCC/8.2.0-2.31.1 # part of the foss-2019a toolchain
module load GCC/7.3.0-2.30 # part of the foss-2018b toolchain
Confirm that you’ve loaded the version of gcc you wanted using gcc -v.
