12</font></h2>
13<font color="#000000">This chapter
14describes the installation of PALM on a Linux workstation (local host). There are two methods to install and run PALM. With the <span style="font-style: italic;">simple method</span>, you can run PALM interactively on the local computer. This method is using the scripts <span style="font-weight: bold;">palm_simple_install</span> and <span style="font-weight: bold;">palm_simple_run</span>.&nbsp;
15The simple method cannot create batch jobs itself, and cannot be used
16to create restart runs. Also file handling and most other features of
17the <span style="font-style: italic;">advanced method</span> are not available. This method is only recommended for those who like to test PALM quickly.<br>
18<br>
19The <span style="font-style: italic;">advanced method</span> is for running PALM in batch mode on a suitable remote computer. The installation procedure is using the script <span style="font-weight: bold;">mbuild</span>. All jobs are started on the local host using the script <b>mrun</b>. The PALM output is automatically sent back from the remote host to the
20local host. Alternatively, <span style="font-weight: bold;">mrun</span>
21can also be used to start PALM in interactive mode on the local host, or
22as a batch job on the local host (if a queueing system like NQS, PBS, or LoadLeveler is
23available).<br>
24<br>
25Only the <span style="font-style: italic;">advanced method</span> gives full access to all PALM features.<br>

36This is already included in many Linux distributions (e.g. SuSe). <span style="font-weight: bold;">subversion requires port 3690 to
37be open for tcp/udp.</span> <span style="font-weight: bold;">If
38there are firewall restrictions concerning this port, the PALM code
39cannot be accessed.</span> The
40user needs a permit to access the PALM repository. For getting a permit
41please contact the PALM group (<a href="mailto:raasch@muk.uni-hannover.de">raasch@muk.uni-hannover.de</a>)
42and define a username under which you like to access the repository.
43You will then receive a password which allows access under this

52systems at computing center HLRN in Hannover (<span style="font-style: italic;">lcsgih</span>), Berlin (<span style="font-style: italic;">lcsgib</span>),
53IBM-Regatta systems<span style="font-style: italic;"></span>

55Kyushu University, Fukuoka (<span style="font-style: italic;">necriam</span>),
56as well as on the Linux cluster of IMUK (<span style="font-style: italic;">lcmuk</span>), Tokyo

59The strings given in brackets are the systems names (host identifiers)

64how to configure <span style="font-weight: bold;">mrun</span>for
65other machines. However, these configurations currently (version
663.7a) allow to run PALM in interactive mode only. Batch mode requires
67manual adjustments for the respective queing system and MPI
68installation in scripts <span style="font-weight: bold;">mrun</span>, <span style="font-weight: bold;">mbuild</span>, and <span style="font-weight: bold;">subjob</span>.<br><span style="font-weight: bold;"></span><span style="font-weight: bold;"></span><span style="font-weight: bold;"></span><span style="font-weight: bold;"></span></font><p style="line-height: 100%;"><font color="#000000">The
69examples given in this chapter refer to an
70installation of PALM on an IMUK Linux workstation and (for the <span style="font-style: italic;">advanced method</span>) the SGI-ICE
71system of HLRN, used as&nbsp;remote host. They are just referred to as local and

73</p><p style="line-height: 100%;">The installation
74process for the <span style="font-style: italic;">advanced method</span> requires a valid

76<p style="line-height: 100%;">The <span style="font-style: italic;">advanced installation method</span> is described below. For the <span style="font-style: italic;">simple  method</span> see the <a href="#simple_installation_method">end of this chapter</a>.<br>

80 All hosts (local as well as remote) are
81accessed via the secure shell (ssh). The user must establish
82passwordless login using the private/public-key mechanism (see e.g. the
83<a href="http://www2.hlrn.de/doc/ssh/index.html">HLRN
84documentation</a>). <b>To ensure proper function of mrun,
85passwordless login must be
86established in both directions, from the local to the remote host as
87well as from the remote to the local host!</b> Test this by
88carrying
89out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">&nbsp;&nbsp;&nbsp;
90</span><span style="font-family: Courier New,Courier,monospace;">ssh&nbsp;
91&lt;username on remote host&gt;@&lt;remote
92IP-address&gt;</span><br> </p> <p style="line-height: 100%;">and on the remote host:<br>
93</p> <p style="line-height: 100%;"><span style="font-family: monospace;">&nbsp;&nbsp;&nbsp;
94</span><span style="font-family: Courier New,Courier,monospace;">ssh&nbsp;
95&lt;username on local host&gt;@&lt;local IP-adddress&gt;</span><br>
96</p> In both cases you should&nbsp;not be
97prompted for a password. <b>Before continuing the further
98installation
99process, this must be absolutely guaranteed!</b> It must also
100be
101guaranteed for <b>all</b> other remote hosts, on which
102PALM shall run.<br><br>Please
103note that on many remote hosts, passwordless login must also work <b>within the remote host</b>, i.e. for ssh connections from the
104remote host to itself. Test this by executing on the remote host:<br>
105  <br>
106  <span style="font-family: Courier New,Courier,monospace;">&nbsp;&nbsp; ssh
107&lt;username on remote host&gt;@&lt;remote IP-address&gt;</span>&nbsp;&nbsp;&nbsp;&nbsp; .<br>
108  <br>
109You should not be prompted
110for a password.<br><br>

113Installation</span></p><p style="line-height: 100%;">The <b>first installation step</b> requires creating a
114set of directories on the local and, for the <span style="font-style: italic;">advanced method</span>, on the
115remote host<span style="font-style: italic;"></span>. These are:</p><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/job_queue<br></div><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/palm<br></div><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">~/palm/current_version<br></div><div style="margin-left: 40px;"><span style="font-family: Courier New,Courier,monospace;">~/palm/current_version/JOBS</span><br></div><p style="line-height: 100%;">The names of these directories can be
116freely selected (except <big><tt><font size="2"><big>~/job_queue</big></font></tt></big>),
117however new users should choose them as suggested, since many
118examples in this documentation as well as all example files are based on these settings. The directory <big><span style="font-family: monospace;">~/palm/current_version</span></big>
119on the local host will be called the working directory from now on. </p>

294be installed and run on other Linux-Cluster-, IBM-AIX, or

296to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;">
297.mrun.config</span>.<br><br>First,
298you have to define the host identifier (a string of arbitrary length)
