mpirun -machinefile './machinefile' -np $SLURM_NPROCS converge-2.4.21-intel --super

2. The meanings of the command-line parameters are as follows:​

  • mpirun: MPI program launch command.
  • -machinefile './machinefile': Specifies the machine list file for running the MPI program, where './machinefile' is the path to the machine list file.
  • -np $SLURM_NPROCS: Specifies the number of processes to use, where $SLURM_NPROCS is an environment variable indicating the number of processes.
  • converge-2.4.21-intel: The name of the MPI program to run.
  • --super: Parameters for the MPI program; refer to the program documentation for specific meanings.
