<p>Please refer to the "IBM Parallel Environment for AIX and Linux Installation
Guide" for details.</p>
 
<p><b>Note:</b> You will use the pe_install.sh script's "-ip_only n" option if
      you want to use an InfiniBand adapter on IBM System p with SuSE 11.</p>
 
<ol>
 
<li>If you are installing IBM Parallel Environment for Linux for the
   first time, you can install this release directly and you will have the
   complete IBM Parallel Environment for Linux product.
<br><br>
 
   To install IBM PE License and the IBM PE product, type:<br><br>
 
        <b>pe_install.sh [-ip_only n]</b><br><br>
 
<b>Note:</b> The above instruction will automatically install and accept the
   IBM PE license.  If you wish to inspect the license agreement type
   'rpm -i IBM_pe_license*.rpm' and then follow the instruction to run
   the license acceptance script.</li>
<br/>
<li> If you have already installed a previous version of the IBM Parallel
   Environment for Linux and want to upgrade to the current release
   level type:
<br><br>
 
        <b>pe_install.sh -install_op U [-ip_only n]</b><br><br> 
</li>
 
 
<li> To install either the HPCT or PDB select the proper RPM file for the
   platform and invoke the 'rpm' command.

<div class="ibm-twisty-body">

<p>This release media contains all RPM images of the IBM Parallel Environment
for Linux V5.2.1.3 (PE5213).</p>
 
<p><b>IBM PE521 supports:</b></p>
<ul class="ibm-bullet-list ibm-no-links">
<li>IBM System p with SUSE Linux Enterprise Server 11</li>
<li>IBM X-Architecture systems with RedHat RHEL 5.4</li>

<p>InfiniBand network support is only available on System p.</p> 
 
<p>This release rolls up all fixes that has gone into previous PE releases.</p>
 
<p><b>The IBM PE5.2.1 components are:</b></p>
<ul class="ibm-bullet-list ibm-no-links">
 <li>IBM PE version: 5.2.1.3</li>
 <li>IBM LAPI version: 3.1.5.3</li>
 <li>IBM High Performance Computing (HPC) Toolkit version: 5.2.0.2</li>

<p>An install script -- pe_install.sh:<br/>
      This script checks your platform and the Linux distro and picks the
      correct set of PE and LAPI rpms for you.  The install script
      will install the PE52 license RPM but it will not install either
      the HPCT and PDB rpms (see below).<br/><br/>
      This install script is convenient to use if you are installing PE
      on a large number of nodes.
</p>
 
<p>HPCT RPMs:<br>
      The HPCT directory contains all HPCT RPMs.<br/><br/>
      The install script does not handle HPCT RPMs.
</p>
 
<p>PDB Parallel Debugger Frontend:<br/>
      The PDB directory contains all PDB RPMs.<br/><br/>
   The install script does not handle PDB RPMs.
   </p>
 
<p> LoadLeveler Resource Manager:<br/>
       The LL_RM directory contains the LoadLeveler Resource Manager.

</div>
<p><b>About IBM PE52 electronic license RPM:</b><br/>
The PE521 electronic license RPM is available from the PE5.2.1.2 CD.<br/><br/>
      PE521 also accepts the electronic license RPM for PE510.  You will not
      need the PE521 license RPM if you have already installed the PE510
      license.<br/><br/>
      You will need to install this PE521 license RPM and run the license
      acceptance script (follow on line instructions) if you are installing
      IBM PE for the first time.<br/><br/>
      If you want to migrate from PE43 you will also need to install
      and accept this new PE license.<br/><br/>
      When using the install script the PE license agreement will be
      accepted automatically.</p>

<p><b>MPI:</b></p>
<div class="ibm-indent">
<p>Fixed a MPI_Cart_sub problem so that this function will comply with the MPI standard to 
return a zero dimension Cartesian topology to all ranks during partitioning of a Cartesian 
topology into subgroups if all of the remaining dimensions are false.</p>
</div>
 
<p><b>POE:</b></p>
<div class=ibm-indent>
<p> The poe command has made improvement to guarantee when a job has requested TASK AFFINITY on a Linux 
system then each task is attached to a CPU set before execution is started.  This fix is for 
Linux only.</p>
</div>
 
<p><b>LAPI:</b></p>
<div class="ibm-indent">
<ol>
<li>Fixed an internal error so that LAPI can handle larger than 4GB messages.</li>
