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`` |mdash| perhaps even in their shell startup files |mdash|
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.
