Run-time system support

The following are command line options for various runtime systems that can be used with configure:

  • --enable-mpirun-prefix-by-default: This option forces the mpirun command to always behave as if --prefix $prefix was present on the command line (where $prefix is the value given to the --prefix option to configure). This prevents most rsh/ssh-based users from needing to modify their shell startup files to set the PATH and/or LD_LIBRARY_PATH for Open MPI on remote nodes. Note, however, that such users may still desire to set PATH perhaps even in their shell startup files so that executables such as mpicc and mpirun can be found without needing to type long path names.
  • --with-alps: Force the building of for the Cray Alps run-time environment. If Alps support cannot be found, configure will abort.

  • --with-lsf=DIR: Specify the directory where the LSF libraries and header files are located. This option is generally only necessary if the LSF headers and libraries are not in default compiler/linker search paths.

    LSF is a resource manager system, frequently used as a batch scheduler in HPC systems.

  • --with-lsf-libdir=DIR: Look in directory for the LSF libraries. By default, Open MPI will look in DIR/lib and DIR/lib64, which covers most cases. This option is only needed for special configurations.
  • --with-slurm: Force the building of Slurm scheduler support.

  • --with-sge: Specify to build support for the Oracle Grid Engine (OGE) resource manager and/or the Open Grid Engine. OGE support is disabled by default; this option must be specified to build OMPI's OGE support.

    The Oracle Grid Engine (OGE) and open Grid Engine packages are resource manager systems, frequently used as a batch scheduler in HPC systems. It used to be called the "Sun Grid Engine", which is why the option is still named --with-sge.

  • --with-tm=DIR: Specify the directory where the TM libraries and header files are located. This option is generally only necessary if the TM headers and libraries are not in default compiler/linker search paths.

    TM is the support library for the Torque and PBS Pro resource manager systems, both of which are frequently used as a batch scheduler in HPC systems.
