Installed Layout
This section describes the default installed layout for the InfiniPath software and
QLogic-supplied MPIs.
The shared libraries are installed in:
/usr/lib for 32-bit applications
/usr/lib64 for 64-bit applications
MPI include files are in:
/usr/include
MPI programming examples and the source for several MPI benchmarks are in:
/usr/share/mpich/examples
InfiniPath utility programs, as well as MPI utilities and benchmarks, are installed
in:
/usr/bin
Documentation is found in:
/usr/share/man
/usr/share/doc/infinipath
/usr/share/doc/mpich-infinipath
Note that license information is found only in usr/share/doc/infinipath.
InfiniPath user documentation can be found on the QLogic web site on the
software download page for your distribution.
Configuration files are found in:
/etc/sysconfig
Init scripts are found in:
/etc/init.d
NOTE:
If QLogic MPI is installed in an alternate location, the argument passed to
--prefix (/usr/mpi/qlogic) replaces the default /usr prefix. QLogic
MPI binaries, documentation, and libraries are installed under that prefix.
However, a few configuration files are installed in /etc regardless of the
desired --prefix. The remaining InfiniPath libraries and tools stay in their
default installation location.
If you have installed the software into an alternate location, the
$MPICH_ROOT environment variable needs to match --prefix.
