MPI Alternatives
|
||
|
|
----------------
|
||
|
|
|
||
|
|
The current Open MPI version of Debian uses the Debian Alternatives system.
|
||
|
|
Although Open MPI might replace most of the existing MPI implementations in the
|
||
|
|
future (see http://www.open-mpi.org/faq/?category=general#why), we decided to
|
||
|
|
not affect any other MPI implementation already installed on your system.
|
||
|
|
|
||
|
|
You can setup Open MPI as default MPI implementation by selecting openmpi as
|
||
|
|
the "mpi" alternative:
|
||
|
|
|
||
|
|
update-alternatives --config mpi
|
||
|
|
|
||
|
|
Please note that there is a bug in update-alternatives (namely #388313) that
|
||
|
|
may cause trouble when you install several development packages of other
|
||
|
|
MPI implementations, i.e. LAM or MPICH.
|
||
|
|
|
||
|
|
If you would like to build Debian packages that link against multiple MPI
|
||
|
|
implementations, we recommend to point your build system to the locations
|
||
|
|
under /usr/lib instead of relying on update-alternatives. This may also allow
|
||
|
|
parallel builds.
