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

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.
