Program build
Once you compiled a binary file (see the Compilation Guide) you need to execute your code. Serial and OpenMP is started directely. For MPI parallelized code you choose between two approaches, namely using srun or mpirun.
Serial and OpenMP parallel code
Please read the page Workflow compiler how to execute
- serial code,
- one OpenMP parallel code, or
- several OpenMP codes simultaneously.
MPI parallel code
Please read the page Workflow Intel MPI how to execute
- MPI parallel code or
- MPI, OpenMP hybrid parallel code.
Please read the page Workflow OpenMPI for details about the MPI library OpenMPI.
