Attention

GPU users: GPU nodes run EL9, while this documentation still reflects the EL7 software stack.

Run module avail on an EL9 login node, or within an interactive session on the relevant GPU type, to see the software available.

The documentation will be updated once all nodes have migrated to EL9.

Intel Compilers

Intel has compilers for C (icc), C++ (icpc) and Fortran (ifort).

To activate both the C/C++ and Fortran compilers use one of:

module load iccifort/2019.1.144-GCC-8.2.0-2.31.1 # subset of intel-2019a toolchain
module load iccifort/2019.5.281 # subset of intel-2019b EasyBuild toolchain
module load iccifort/2020.1.217 # subset of intel-2020a EasyBuild toolchain
module load iccifort/2020.4.304 # subset of intel-2020b EasyBuild toolchain

Which implicitly also load versions of the GCC compiler.

For older versions of the intel EasyBuild toolchain you can also load icc/icpc and ifort independently using one of:

module load icc/2019.1.144-GCC-8.2.0-2.31.1     # subset of intel-2019a toolchain
module load ifort/2019.1.144-GCC-8.2.0-2.31.1   # subset of intel-2019a toolchain

Again, versions of the GCC compiler are implicitly loaded.

Confirm that you’ve loaded the version of icc/icpc you require:

icc -v

Documentation

man pages are available on the system. Once you have loaded the required version of icc/icpc/ifort, run:

man icc
man ifort
