Code Compilation

MPI parallel code

module load intel
module load impi
mpiicc -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.c
mpiifort -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.f90
mpiicpc -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.cpp

MPI, OpenMP parallel code

module load intel
module load impi
mpiicc -qopenmp  -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.c
mpiifort -qopenmp -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.f90 
mpiicpc -qopenmp -Wl,-rpath,$LD_RUN_PATH -o hello.bin hello.cpp

Code execution

You need to start the MPI parallelized code on the system. You can choose between two approaches, namely using mpirun or srun.

Using mpirun

Using mpirun the pinning is controled by the MPI library. Pinning by slurm you need to switch off by adding export SLURM_CPU_BIND=none.
