Ubuntu HPC Install and Configure Modules

Home > Ubuntu > HPC setup with openpbs and openmpi > Install and Configure Modules

1. Create directory for modules path in master node share path

   mkdir -p /export/modules/

2. Configure mpi module file in master node
   1. Create directory for mpi

      mkdir -p /export/modules/mpi

   2. Create '/export/modules/mpi/mpi-4.1.1' module file with:

      #%Module 1.0
      conflict                mpi
      prepend-path PATH {/export/apps/mpi/openmpi-4.1.1/bin};
      prepend-path LD_LIBRARY_PATH {/export/apps/mpi/openmpi-4.1.1/lib};
      prepend-path MANPATH {/export/apps/mpi/openmpi-4.1.1/share/man};
      prepend-path LD_RUN_PATH {/export/apps/mpi/openmpi-4.1.1/lib};
      prepend-path C_INCLUDE_PATH {/export/apps/mpi/openmpi-4.1.1/include};
      prepend-path CXX_INCLUDE_PATH {/export/apps/mpi/openmpi-4.1.1/include};
      prepend-path CPP_INCLUDE_PATH {/export/apps/mpi/openmpi-4.1.1/include};
      prepend-path CPLUS_INCLUDE_PATH {/export/apps/mpi/openmpi-4.1.1/include};

   3. For new module path to work, Logout and login back from all nodes
   4. Check the available modules in all nodes

      module avail

3. As a HPC user load mpi module and try to run stress job again:

   module load mpi/mpi-4.1.1
   mpirun -host master,<node-1>,<node-2> -n 3 /usr/bin/stress --cpu 4 --vm 2 --vm-bytes 300M --timeout 60s
