Open MPI: Version 2.0.3 Source RPM Notes

  |   Home   |   Support   |   FAQ   |  

Because every parallel computation environment is different, Open MPI is a highly configurable piece of software. As such, a single set of build options is not sufficient to meet everyone's needs. The source RPM therefore accepts a wide variety of configuration options on the "rpmbuild --rebuild" command line. The following text describes the options that are available.

A script to build an Open MPI RPM from a source tarball is available here, and is referred to as "buildrpm.sh" in the text below. Additionally, you can build an Open MPI RPM from the SRPM (also described below).

The text below is specific to the v2.0.x series of Open MPI and is available here in a printer-friendly format.

Note that the spec file (that the text below refers to) has many more comments and explanations of rpmbuild-time configuration options, and is available here.

===========================================================================

Note that you probably want to download the latest release of the SRPM
for any given Open MPI version.  The SRPM release number is the
version after the dash in the SRPM filename.  For example,
"openmpi-1.6.3-2.src.rpm" is the 2nd release of the SRPM for Open MPI
v1.6.3.  Subsequent releases of SRPMs typically contain bug fixes for
the RPM packaging, but not Open MPI itself.

The buildrpm.sh script takes a single mandatory argument -- a filename
pointing to an Open MPI tarball (may be either .gz or .bz2).  It will
create one or more RPMs from this tarball:

1. Source RPM
2. "All in one" RPM, where all of Open MPI is put into a single RPM.
3. "Multiple" RPM, where Open MPI is split into several sub-package
   RPMs:
   - openmpi-runtime
   - openmpi-devel
   - openmpi-docs

The folowing arguments could be used to affect script behaviour.
Please, do NOT set the same settings with parameters and config vars.

-b
   If you specify this option, only the all-in-one binary RPM will
   be built. By default, only the source RPM (SRPM) is built. Other
   parameters that affect the all-in-one binary RPM will be ignored
   unless this option is specified.

-n name
   This option will change the name of the produced RPM to the "name".
   It is useful to use with "-o" and "-m" options if you want to have
   multiple Open MPI versions installed simultaneously in the same
   enviroment. Requires use of option "-b".

-o
   With this option the install path of the binary RPM will be changed
   to /opt/_NAME_/_VERSION_. Requires use of option "-b".

-m
   This option causes the RPM to also install modulefiles
   to the location specified in the specfile. Requires use of option "-b".

-i
   Also build a debuginfo RPM. By default, the debuginfo RPM is not built.
   Requires use of option "-b".

-f lf_location
   Include support for Libfabric. "lf_location" is Libfabric install
   path. Requires use of option "-b".

-t tm_location
   Include support for Torque/PBS Pro. "tm_location" is path of the
   Torque/PBS Pro header files. Requires use of option "-b".

-d
   Build with debugging support. By default,
   the RPM is built without debugging support.

-c parameter
   Add custom configure parameter.

-r parameter
   Add custom RPM build parameter.

-s
   If specified, the script will try to unpack the openmpi.spec
   file from the tarball specified on the command line. By default,
   the script will look for the specfile in the current directory.

-h
   Prints script usage information.


Target architecture is currently hard-coded in the beginning
of the buildrpm.sh script.

Alternatively, you can build directly from the openmpi.spec spec file
or SRPM directly.  Many options can be passed to the building process
via rpmbuild's --define option (there are older versions of rpmbuild
that do not seem to handle --define'd values properly in all cases,
but we generally don't care about those old versions of rpmbuild...).
The available options are described in the comments in the beginning
of the spec file in this directory.
