ParaStation5 Administrator's Guide

# rpm -Uv psdoc-5.0.0-1.noarch.rpm

All the PDF and HTML files will be installed within the directory

/opt/parastation/doc

, the manual

pages will reside in

/opt/parastation/man

.

The intended starting point to browse the HTML version of the documentation is

file:///opt/

parastation/doc/html/index.html

.

The documentation is available in two PDF files called

adminguide.pdf

for the ParaStation5

Administrator's Guide and

userguide.pdf

for the ParaStation5 User's Guide. Both can be found in the

directory

/opt/parastation/doc/pdf

.

In order to enable the manual pages to the users please consult the documentation of the man(1) command
and the remark in Section 3.2, “Directory structure”, on how to do this.

3.5. Installing MPI

The standard for the implementation of parallel applications on distributed memory machines like clusters
is MPI, the Message Passing Interface. In order to enable a ParaStation5 cluster for the development and
execution of MPI programs, the installation of an adapted version of MPIch2 is necessary. A corresponding
RPM packet can be found within the download section of the ParaStation homepage.

The corresponding package

psmpi2

follows the common naming conventions of all ParaStation5 packets.

Beside the plain MPI package (

psmpi2

), which is compiled using the GNU gcc compiler, other versions

of the MPI packet are available, which are built using different compilers like the PGI or Intel compilers on
the Intel IA32 platform, the Intel compiler on the IA64 platform and the PGI, Intel and Pathscale compiler
on X86_64 platform. These packets of course will depend on the corresponding compilers to be installed.
Keep in mind that the use of this compilers might require further licenses.

After downloading the correct MPI package make sure to be root. In order to install MPIch for ParaStation5
from the rpm file, the command

# rpm -Uv psmpi2.5.0.0-1.i586.rpm

must be executed.

The command will extract the ParaStation5 MPI package to the directory

/opt/parastation/mpi2

.

In order to enable the MPI commands to the users make sure that the directory

/opt/parastation/

mpi2/bin

is included into the system wide

PATH

environment variable. Furthermore the administrator

might want to enable the MPI manual pages for all users. These pages reside in

/opt/parastation/

mpi2/man

. Please consult the documentation of the man(1) command and the remark in Section 3.2,

“Directory structure” on how to do this.

In general, all versions of ParaStation5 MPI supporting different compilers can be installed in parallel. The
files will be copied to the directories

/opt/parastation/mpi2

(for GNU gcc),

/opt/parastation/

mpi2-intel

(for Intel compiler) or

/opt/parastation/mpi2-pgi

(for Portland Group compiler),

depending on the compiler version supported by the MPI package.
