The recommended way to install ParaStation MPI is the installation of packages using the rpm command. This is the preferred method on all SuSE or Red Hat based systems.
Packages containing the different parts of the ParaStation MPI system can be obtained from the download section of the ParaStation MPI homepage.
At least two packages are needed, one containing the management part, the other one providing the communication part of the ParaStation MPI system. Beside this core system, packages supplying MPIch for GNU, Intel and Portland Group are available. A documentation package is also obtainable.
The full names of the RPM files follow a simple structure:
name-x.y.z-n.arch.rpm
	where name denotes the name and thus the content of
	the packet, x.y.z describes the version
	number, n the build number and
	arch is the architecture, i.e. one of
	i586, ia64,
	x86_64, ppc or
	noarch. The latter is used e.g. for the
	documentation packet.
      
        The package called psmgmt holds the
        management part of ParaStation MPI. This package is required for any
	installation of the ParaStation MPI system, independent of the underlying
	communication platform.
      
	The communication libraries and modules for ParaStation MPI come with the
	pscom package. As explained, all filenames are
	followed by an individual version number, the build date and the
	architecture.
      
        The MPI libraries and tools are included in the package
        psmpi2, 
        psmpi2-intel or
        psmpi2-pgi
        for the respective
        compilers.
      
The versions available on the ParaStation MPI homepage at a time are tested to work properly together. It's recommended to install always the corresponding package versions. If only a part of the installation should be updated (i.e. only the management part while keeping the communication part untouched) the corresponding release notes should be consulted in order to verify that the intended combination is supported.
	The release notes of the different packages will either be found within
	the installation directory
        /opt/parastation or on the download
        section of the ParaStation MPI homepage.
      
Please note that the individual version numbers of the distinct packages building the ParaStation MPI system do not necessarily have to match.
To build proper RPM packages suitable for a particular setup, the source code for the ParaStation MPI packages can be downloaded from www.parastation.com/downloads [2] .
Typically, it is not necessary to recompile the ParaStation MPI packages, as the provided precompiled packages will install on all major distributions.
Only the kernel modules (if required) should be compiled to provide modules suitable for the current Linux kernel, see below.
        To build the psmgmt package, use
      
# rpmbuild --rebuild psmgmt.5.0.0-0.src.rpm
        After installing the psmgmt package, the
        pscom package can be built using
      
# rpm -Uv psmgmt.5.0.0-0.i586.rpm # rpmbuild --rebuild pscom.5.0.0-0.src.rpm
        This will build the packages
        pscom-5.0.0-0.i586.rpm and 
        pscom-modules-5.0.0-0.i586.rpm.
        The architecture will of course vary depending on the system
        the packages are built on.
      
While compiling the package, support for InfiniBand will be included, if one of the following files where found:
Table 3.1. Supported InfiniBand implementations
| File | Version | 
|---|---|
/usr/include/infiniband/verbs.h | OpenFabrics | 
/usr/mellanox/include/vapi/evapi.h | Mellanox | 
/usr/local/ofed/include/verbs.h | OpenFabrics (Voltaire) | 
        To enable Myrinet GM, the environment variable
        GM_HOME must be set.
      
        To generate the 
        pscom-modules package, holding
        the ParaStation protocol-specific kernel modules and patched device
        drivers 
        only, use the command
      
# rpmbuild --rebuild --with modules pscom.5.0.0-0.src.rpm
        After installing the pscom package, the
        MPIch2 package can be built using
      
# rpm -Uv pscom.5.0.0-0.i586.rpm # rpmbuild --rebuild psmpi2-5.0.0.src.rpm
        This will create an installable MPIch RPM package, based on
        gcc. Support for other compilers can be enabled using the
        --with  options.
        compilerCompiler could be
        intel for Intel icc or
        pgi for Portland Group pgi.
        The option
        g77_ will use gcc, rendering symbol
        names with a single underscore prefixed.
      
The installation on the cluster nodes has to be performed with administrator privileges. The packages are installed using the rpm -U command:
# rpm -Uv psmgmt.5.0.0-0.i586.rpm pscom.5.0.0-0.i586.rpm \ pscom-modules.5.0.0-0.i586.rpm
        This will copy all
	the necessary files to /opt/parastation
        and the kernel modules to
        /lib/modules/.
      kernelversion/kernel/drivers/net/ps4
        On a frontend node or file server, the
        pscom-modules package is only required,
        if this node should run processes of a parallel task.
        If the frontend or fileserver node is not configured to run
        compute processes of parallel tasks, the installation of
        the pscom-modules package may be skipped.
        For details how to configure frontend nodes, refer to the section called “Configuration of the ParaStation MPI system”.
      
        To enable the ParaStation MPI version of the e1000 or bcm5700 network
        drivers, rename (or delete) the original version of this
        driver in use which is typically located in the system directory
        /lib/modules/
        or
        kernelversion/kernel/kernel/drivers/net/e1000bcm,
        respectively.
        See modinfo
        e1000 for details.
        The module dependency database must be rebuild using the command
        depmod.
        See the section called “Enable optimized network drivers” for
        details.
        
It is not required to use the ParaStation MPI version of the e1000 or bcm5700 driver, as the p4sock protocol of ParaStation MPI is able to use every network driver within the Linux kernel. However, to increase performance and to minimize latency, it's highly recommended.
Using the provided drivers does not influence other network communication.
        While installing the ParaStation MPI management RPM, the file
        /etc/xinetd/psidstarter is installed.
        This enables remote startup of ParaStation MPI daemons using the
        xinetd(8).
      
The xinetd daemon will be triggered to read this file by executing:
/etc/init.d/xinetd reload
Refer to the section called “Changing the default ports for psid(8)” on how to change the default network port used by the psid(8).
        In case the system still uses the older
        xinet(8) server to startup
        network services, please add the following lines to
        /etc/services:
      
# # ParaStation daemon # psid stream tcp nowait root /opt/parastation/bin/psid psid
        Add the next lines to /etc/inetd.conf:
      
# ParaStation entries psid 888/tcp # ParaStation Daemon Start Port # end of ParaStation entries
