Usage
Intel compilers (icc, icpc, ifort) are available through modules
module load intel
Warning: Do not use the -xHost option as the frontend nodes are a different architecture than the compute nodes and you will lose performance!
Note: Since 2021 Intel provide newer LLVM-based Intel oneAPI compilers (icx, icpx, ifx) that are supposed to replace his classic compilers (icc, icpc, ifort). These are included in our Intel modules starting from version 2021.5/2022.0. But be aware that the performance of your applications may be better when compiled with the older classic compilers - especially with ifort. Please check the porting guides from Intel for C/C++ or Fortran to adapt your applications.
