Changing the used compiler and linking the library are done by loading the necessary modules.

1. Display a list of loaded modules．

% module list

2. Check available modules

% module avail

3. Load/unload modules

 % module load/unload  <module name>

4. Unload all loaded modules

 % module purge

例1. Intel Compiler(OneAPI) + Intel MPI + Intel MKL

  % module load oneapi-intel/2021.1.1

例2．Intel Compiler(OneAPI) + OpenMPI + Intel MKL

  % module load openmpi/4.1.1/intel
  % module load compiler/2021.1.1
  % module load mkl/2021.1.1

例3.  GNU Compiler + OpenMPI + FFTW3

  % module load openmpi/4.1.1/gcc
  % module load fftw/3.3.9

Ex1. Intel Compiler(OneAPI) + Intel MPI + Intel MKL

  % module load oneapi-intel/2021.1.1
  % mpiicc -O3 -o prog.exe prog.c  (# MPI only)
  % mpiicc -O3 -o prog.exe -qopenmp prog.c  ( #MPI+OpenMP Hybrid)

Ex2．Intel Compiler(OneAPI) + OpenMPI + Intel MKL

  % module load openmpi/4.1.1/intel
  % module load compiler/2021.1.1
  % module load mkl/2021.1.1
  % mpicc -O3 -o prog.exe prog.c (# MPI only)
  % mpicc -O3 -o prog.exe -qopenmp prog.c ( #MPI+OpenMP Hybrid)

Ex3.  GNU Compiler + OpenMPI + FFTW3

  % module load openmpi/4.1.1/gcc
  % module load fftw/3.3.9
  % mpicc -O3 -o prog.exe prog.c (# MPI only)
  % mpicc -O3 -o prog.exe -fopenmp prog.c ( #MPI+OpenMP Hybrid)

Ex4. Intel Compiler(OneAPI) + Intel MPI + Intel MKL

  % module load oneapi-intel/2021.1.1
  % mpiicc -O3 -o prog.exe -qopenmp prog.c -L${MKLROOT}/lib/intel64 -liomp5 -lpthread -lm -ldl -mkl=sequential　( #MPI+OpenMP Hybrid)

* For detail of MKL, please refer to Intel Link Line Advisor.
