Intel oneAPI compilers

Guidance last updated: 20 October 2026

The Intel oneAPI compilers provide C, C++ and Fortran compilers for use on Stanage.

Usage

After connecting to Stanage (see Establishing a SSH connection), start an interactive session:

salloc

You can load a specific version with one of the following commands:

module load intel-compilers/2025.3.3
module load intel-compilers/2025.2.0
module load intel-compilers/2024.2.0
module load intel-compilers/2023.0.0
module load intel-compilers/2022.2.1
module load intel-compilers/2022.2.0

module load intel-compilers/2025.3.3
module load intel-compilers/2025.2.0
module load intel-compilers/2023.0.0
module load intel-compilers/2022.2.1
module load intel-compilers/2022.2.0

The module loads its GCCcore and binutils dependencies automatically.

Compiler commands

The following commands invoke the oneAPI compilers:

Language	Command
C	`icx`
C++	`icpx`
Fortran	`ifx`

Some older versions also provide the classic compilers icc, icpc and ifort. Their availability depends on the module version.

Compiling a program

After loading the module, compile your source file using the appropriate compiler:

icx -O2 program.c -o program
icpx -O2 program.cpp -o program
ifx -O2 program.f90 -o program

Run compiled programs within a Slurm allocation.

Example batch submission

The following example batch submission script compiles and runs three C, C++ and Fortran source files, program.c, program.cpp and program.f90, located in the submission directory:

#!/bin/bash
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=1
#SBATCH --mem-per-cpu=2000
#SBATCH --time=00:05:00

set -e
export SLURM_EXPORT_ENV=ALL
module load intel-compilers/2025.3.3

icx -O2 program.c -o program_c
icpx -O2 program.cpp -o program_cpp
ifx -O2 program.f90 -o program_fortran

srun ./program_c
srun ./program_cpp
srun ./program_fortran

Installation notes

intel-compilers was installed using Easybuild, build details can be found in $EBROOTINTELMINCOMPILERS/easybuild with a given module loaded.
