LAMMPS

Building LAMMPS with Arm Compiler


Overview Before you begin Procedure Related information

Procedure

  1. Download the LAMMPS source from the LAMMPS repository, unpack the tarball, and change into the unpacked lammps-11Aug17 directory:

    wget http://lammps.sandia.gov/tars/lammps-11Aug17.tar.gz
    tar zxf lammps-11Aug17.tar.gz
    cd lammps-11Aug17/
  2. Download the Makefile.arm_openmpi and Makefile.arm_serial Makefiles from the LAMMPS Gitlab page.

  3. Copy the downloaded Makefile.arm_openmpi and Makefile.arm_serial Makefiles to the src/MAKE/OPTIONS directory of the unpacked LAMMPS package.

    cp </path/to/>Makefile.arm_openmpi src/MAKE/OPTIONS
    cp </path/to/>Makefile.arm_serial src/MAKE/OPTIONS

    replacing </path/to/> with the path to your downloaded Makefiles.

  4. Configure your environment for Arm Compiler and Arm Performance Libraries:

    module load Generic-AArch64/<Linux_dist>/<dist_version>/arm-hpc-compiler-18.0/armpl/18.0.0

    replacing <Linux_dist> and <dist_version> with your respective Linux distribution and version, respectively. For example, for RHEL v7.3:

    module load Generic-AArch64/RHEL/7.3/arm-hpc-compiler-18.0/armpl/18.0.0
  5. Change to the src directory:

    cd src
  6. Build Open MPI and serial versions of LAMMPS using the lmp_arm_openmpi and lmp_arm_serial Makefiles, respectively:

    • For a basic build, use:
      make -j 64 arm_openmpi
      make clean-all
      cd STUBS
      make
      cd ../
      make arm_serial
    • To build a more complete set of packages, use:
      make yes-std
      make no-lib make -j 64 arm_openmpi make clean-all cd STUBS make cd ../ make -j 64 arm_serial

      Note: These instructions do not build packages requiring external libraries. The executables lmp_arm_openmpi and lmp_arm_serial are produced.
