Compilers¶
You can check all the available compilers by following command:
module load keyword compiler
Available compilers
There are several compilers for different programming languages available on the cluster:
* C/C++
* Fortran 77/90/95/
* Java
* NVIDIA CUDA
The C/C++ and Fortran compilers are provided by:
Open source:
* GNU GCC
* Clang/LLVM
Commercial licenses:
* Intel
Common toolchains¶
You can set up your environment with desired toolchain (e.g. intel toolchain version 2022a) as:
module load intel/2022a
Compiler toolchains
Currently, two different common (compiler) toolchains are being maintained: intel and foss.
The foss common compiler toolchain consists entirely of open source software, i.e.:
* binutils
* the GNU compiler collection (gcc,g++,gfortran)
* the Open MPI library
* the FlexiBLAS library (OpenBLAS + LAPACK)
* the ScaLAPACK library
* the FFTW library
The intel compiler toolchain consists of the Intel compilers and libraries, i.e.:
* the Intel C/C++/Fortran compilers (icc, icpc ifort)
* the Intel MPI library
* the Intel Math Kernel library (MKL) for BLAS, LAPACK and FFT functionalities.
