12<font color="#000000">This chapter
13describes the installation of PALM on a Linux workstation (local host)
14and a suitable remote computer, on which the
15model runs are to be carried out. The local host is used to
16start batch jobs with <b>mrun</b> and to analyze the
17results
18which are produced by the model on the remote host and send back to the
19local host. Alternatively, <span style="font-weight: bold;">mrun</span>
20can also be used to start PALM on the local host in interactive mode or
21as a batch job (if a queueing system like NQS, PBS, or LoadLeveler is

61examples given in this chapter refer to an
62installation of PALM on an IMUK Linux workstation and the SGI-ICE
63system of
64the HLRN used as&nbsp;remote host. They are just called local and

66</p><p style="line-height: 100%;">The installation
67process requires a valid
68account on the local and on the remote host as well.<br>
69&nbsp; </p>
70<ul> All hosts (local as well as remote) are
71accessed via the secure shell (ssh). The user must establish
72passwordless login using the private/public-key mechanism (see e.g. the
73<a href="http://www2.hlrn.de/doc/ssh/index.html">HLRN
74documentation</a>). <b>To ensure proper function of mrun,
75passwordless login must be
76established in both directions, from the local to the remote host as
77well as from the remote to the local host!</b> Test this by
78carrying
79out e.g. on the local host: <p style="line-height: 100%;"><span style="font-family: monospace;">&nbsp;&nbsp;&nbsp;
80</span><span style="font-family: Courier New,Courier,monospace;">ssh&nbsp;

88installation
89process, this must be absolutely guaranteed!</b> This must also
90be
91guaranteed for <b>all</b> other remote hosts, on which
92PALM shall run.<br><br>Please
93note that on many remote hosts, passwordless login must also be
94established <b>within the remote host</b>, i.e. from the
95remote host to itself. Test this by executing on the remote host: <span style="font-family: Courier New,Courier,monospace;">ssh
96&lt;remote IP-address&gt;</span>. You should not be prompted

99the <b>first installation step</b> a

102are
103freely selectable (except <big><tt><font size="2"><big>~/job_queue</big></font></tt></big>),
104however new users should use them as suggested, since many
105examples in this documentation as well as all example files are
106assuming these settings. The directory <big><span style="font-family: monospace;">~/palm/current_version</span></big>
107on the local host will be called the working directory from now on. </p>

284from version 3.2a, beside the default hosts (HLRN, etc.), PALM can also
285be installed and run on other Linux-Cluster-, IBM-AIX, or
286NEC-SX-systems. To configure PALM for a non-default host only requires
287to add some lines to the configuration file<span style="font-family: Courier New,Courier,monospace;">
288.mrun.config</span>.<br><br>First,
289you have to define the host identifier (a string of arbitrary length)
290under which your local host shall be identified by adding a line<br><br></font><div style="margin-left: 40px;"><span style="font-family: Courier New,Courier,monospace;">%host_identifier
291&nbsp;&lt;hostname&gt; &nbsp;&lt;host
292identifier&gt;</span><br></div><br>to the
293configuration file (best to do this in the section where the other
294default host identifiers are defined). Here<span style="font-family: Courier New,Courier,monospace;">
295&lt;hostname&gt; </span>must be the name of your local
296host as provided by the unix-command "<span style="font-family: Courier New,Courier,monospace;">hostname</span>".
297The first characters of<span style="font-family: Courier New,Courier,monospace;">
298&lt;host identifier&gt; </span>have to be "<span style="font-family: Courier New,Courier,monospace;">lc</span>",
299if your system is (part of) a linux-cluster, "<span style="font-family: Courier New,Courier,monospace;">ibm</span>",
300or "<span style="font-family: Courier New,Courier,monospace;">nec</span>"
301in case of an IBM-AIX- or NEC-SX-system, respectively. For example, if
302you want to install on a linux-cluster, the line may read as<br><br><div style="margin-left: 40px;">%host_identifier &nbsp;foo
303&nbsp;lc_bar<br></div><br>In
304the second step, you have to give all informations neccessary to
305compile and run PALM on your local host by adding an additional section
306to the configuration file:<br><br><div style="margin-left: 40px; font-family: Courier New,Courier,monospace;">%remote_username&nbsp;&nbsp;

328and <span style="font-weight: bold;">mbuild</span>,
329while the second column defines its value. The third column has to be
330the host identifier as defined above, and the last column in each line
331must contain the string "<span style="font-family: Courier New,Courier,monospace;">parallel</span>".
332Otherwise, the respective line(s) will be interpreted as belonging to

335appropriate settings for your local host:<br><ul><li><span style="font-family: Courier New,Courier,monospace;">&lt;1&gt;

344giving <span style="font-family: Courier New,Courier,monospace;">-DMPI_REAL=MPI_DOUBLE_PRECISION
345-DMPI_2REAL=MPI_2DOUBLE_PRECISION</span>. To switch on the NetCDF
346support, you also have to give <span style="font-family: Courier New,Courier,monospace;">-D__netcdf</span>
347and <span style="font-family: Courier New,Courier,monospace;">-D__netcdf_64bit</span>
348(if you like to have 64bit NetCDF output).</li><li><span style="font-family: Courier New,Courier,monospace;">&lt;6&gt;

353allways switch on double precision (e.g. <span style="font-family: Courier New,Courier,monospace;">-r8</span>)
